UniFi gear is built for desks and shelves. Most of it is half-width, fanless, and beautifully styled — and that means the day you decide to consolidate your homelab into a rack, you discover that almost none of it has rack ears in the box. This guide walks through how to mount the entire current UniFi lineup in a 10-inch rack, which models actually fit, where you'll trip yourself up, and where stepping up to a 19-inch rack starts to make sense.
It's written for homelabbers and small-business folks running UniFi as their full stack: gateway, switches, Cloud Key, the works. If you're an MSP putting a single Dream Machine on a customer's wall, the geometry still applies — skim past the homelab-specific build sheets at the end.
Why a 10-inch rack for UniFi at all
The 10-inch rack standard (sometimes called a "half-rack" or "mini-rack") is the smaller cousin of the 19-inch standard defined in EIA-310-D. The mounting holes are 254 mm apart center-to-center, and usable interior width sits around 200–210 mm depending on the cabinet. A 1U slot is still 44.45 mm tall (1.75 in) — that part doesn't change between 10" and 19" gear; only the width does.
For a UniFi-centric setup that's three reasons big:
- Footprint. A 12U 10-inch wall cabinet is roughly 30 cm wide. A 12U 19-inch wall cabinet is closer to 60 cm. If you're squeezing a homelab into a closet, an apartment hallway, or under a desk, that difference is the difference between "fits" and "doesn't."
- Cost. 10-inch cabinets from DeskPi, NavePoint, and the various Amazon white-label vendors run roughly half the price of equivalent 19-inch frames. The savings let you spend more on the gear that actually goes inside.
- Match. Most UniFi devices are 8–10 inches wide already. A 19-inch rack just means more empty bracket on either side. A 10-inch rack hugs them.
The catch — and there's always a catch — is that some UniFi devices simply don't fit in 254 mm of usable rack width once you account for cable bend radius and bracket flanges. Those are the ones we'll flag as you go.
The form-factor reality check
Before you order anything, check the device width against the cabinet's usable interior width (not the nominal "10 inches" — the inside, between rails). A few rules of thumb that hold for the current UniFi lineup:
- UniFi Express, Gateway Lite, and the small Flex Mini family are well under 200 mm wide. They drop into a 10-inch rack with room to spare.
- Cloud Gateway Ultra, Cloud Gateway Max, and the Express 7 are wider — closer to the limit but still 10"-compatible with the right bracket.
- Cloud Gateway Fiber is the awkward middle child; it fits a 10-inch rack but the SFP+ ports want clearance you may not have if you also have a switch on the row above. Plan vertical spacing accordingly.
- USW-Pro and most of the rack-native UniFi switches (USW-Pro-24, USW-Pro-Aggregation, USW-Enterprise, anything in the "Pro Max" line above 16 ports) are 19-inch native. Don't try to cram them into a 10-inch frame; the rack ears are not detachable in any useful way.
If your build sheet has a USW-Pro-24 on it, you're already on the path to a 19-inch rack. There's nothing wrong with running both — a 19" rack for the heavy switching, a small 10" cabinet elsewhere for the gateway and the Cloud Key — but for the rest of this guide we'll assume an all-10-inch build.
Mounting UniFi gateways in a 10-inch rack
The gateway is the natural anchor for any UniFi rack. It's the device that's running 24/7 with the least tolerance for being unplugged, and it's usually the heaviest cable load. Mount it where you can reach the WAN port without pulling the rack apart.
UniFi Express (UX) and Gateway Lite (UXG-Lite)
These two share a near-identical chassis — small, fanless, and just under 100 mm wide. They're the gateway of choice for a sub-100-Mbps homelab or a small office. We make a 10" UniFi Express & Gateway Lite mini rack mount with 2 keystones that holds either device flush in 1U, with two keystone cutouts for whatever you want to break out — typically WAN passthrough and a console port.
If you're already on a 19-inch rack and want to use the same device there instead, the same family is available as a 19" modular Express/Gateway Lite mount. Same device, different bracket; the modular design lets you fill the rest of the U with blanks or other gear.
UniFi Express 7
The Express 7 is wider and heavier than the original Express. We treat it as its own SKU: a 10" Express 7 mini rack mount for the small frame and a 19" modular Express 7 mount if you've already gone large. Both keep the unit's front panel display visible, which matters more than you'd think — the Express 7 is the rare gateway you actually want to look at.
Cloud Gateway Ultra, Cloud Gateway Max
The Cloud Gateway Ultra and Max share a chassis. They're a step up from the Express line in throughput and price, and they're wide enough that a 10-inch mount is genuinely tight. Workable, but tight. For most builds we recommend the 19" modular Cloud Gateway Ultra/Max mount over the 10-inch — by the time you're spending Cloud Gateway Ultra money, the cabinet upgrade is in budget.
Cloud Gateway Fiber (UCG-Fiber)
Two SKUs cover this one: a 10" Cloud Gateway Fiber mount and a 19" Cloud Gateway Fiber mount. Either way, plan for SFP+ patch cable bend radius. LC duplex won't take a 90° turn cleanly; you need at least 30–40 mm of clearance behind the unit before the cable can route up or down.
UniFi Security Gateway (USG) and the older USG-Pro
The original USG is end-of-life from Ubiquiti's side, but plenty of homelabs still run them. There's a 10" USG rack mount for the small chassis and a 19" USG + Cloud Key Gen2 Plus combo mount if you want both devices in a single 1U slot — a tidy combination if your gear predates the all-in-one Dream Machine line.
Mounting UniFi switches in a 10-inch rack
Most UniFi switches under 16 ports were designed to look good on a desk. They're usually 8–10 inches wide, fanless or low-noise, and have rubber feet you'll want to leave on (don't pry them off — they double as airflow standoffs).
USW-Lite-8 PoE and USW-Lite-16 PoE
The Lite-8 PoE is the standard small homelab switch. We make a 10" USW-Lite-8 PoE mini rack mount and the matching 19" modular version. Both are 1U.
The Lite-16 PoE is bigger and heavier — it gets a 10" Lite-16 PoE mini rack mount in 1U and a 19" Lite-16 PoE 1U mount. Note: there's also a 19" 2U mount for the Lite-16 PoE if you want extra clearance for cabling on top — useful if you're patching all 16 ports and want the cables to breathe.
USW Flex Mini and Flex Mini 2.5G
The Flex Mini is the smallest UniFi switch — 5 ports, palm-sized. It's almost wasteful to give it a full 1U, so our brackets pair it with keystone cutouts: a 10" Flex Mini mount with 3 keystone jacks, or a 10" Flex Mini 2.5G mount with 1 keystone jack. The 19-inch versions follow the same pattern: Flex Mini 2.5G 19" modular and Flex Mini 19" with 3 keystones.
The keystone slots earn their keep — patch a couple of pulled-through Cat6 runs into the same 1U as the switch and you've eliminated a whole patch panel from your build.
USW Flex 2.5G 8
The 8-port 2.5G version of the Flex line gets its own 1U bracket: 10" Flex 2.5G 8 mini rack mount or 19" Flex 2.5G 8 modular mount. The 2.5G models run noticeably warmer than the 1G Flex — leave the rubber feet on (or design in 5 mm of standoff) so the underside can shed heat.
USW Flex XG and Switch Pro XG 8 PoE
For 10G in a small package, you're looking at either the Flex XG (4-port 10G, no PoE) or the Switch Pro XG 8 PoE (8-port, half 10G with PoE+). Mounts: 10" Flex XG mini mount, 19" Flex XG modular mount, 10" Pro XG 8 PoE mini mount, and 19" Pro XG 8 PoE mount.
One note on the Pro XG 8 PoE: it has a small fan. It's not loud, but it's not silent either. If you're putting your rack in a bedroom, plan for that.
USW-Ultra
The Ultra is the newer fanless 8-port managed switch with two SFP+ uplinks. Excellent for a quiet homelab: 10" USW-Ultra modular mount or 19" USW-Ultra modular mount.
UniFi Switch 8 (the original)
If you're still running the original UniFi Switch 8 (non-PoE, non-Lite), there's a 10" Switch 8 rack mount for it. Worth checking your serial — the chassis was redesigned a couple of times — but the 1U bracket fits all the iterations we've tested.
Cloud Key, accessories, and the rest
The 19" Cloud Key Gen2 Plus modular mount is the answer for the Cloud Key Gen2 Plus on its own. If you're running an older USG plus a Cloud Key, the combined 19" USG + Cloud Key Gen2 Plus 1U mount puts both in a single slot.
The UniFi PowerAmp 2U rack mount covers PowerAmp power-protection units. PowerAmp is 2U for thermal headroom — don't try to squeeze it into 1U with a custom bracket; it needs the airflow.
For routing-only setups still on the Ubiquiti EdgeRouter X, there's a 10" EdgeRouter X rack mount. The ER-X isn't part of the modern UniFi line, but it's still a workhorse for "just the router" homelabs.
The 19-inch question: when to step up
Stay in 10-inch territory if your build sheet looks like:
- Express, Gateway Lite, or Cloud Gateway Fiber as the gateway
- One Lite-8 or Lite-16 PoE as the main switch
- Optional Cloud Key, optional Flex Mini for IoT
- Total under 12U with cable management
Step up to a 19-inch frame if any of these hit:
- You want a USW-Pro-24, USW-Enterprise, or anything Aggregation-class
- You're running a rackmount UPS (every rackmount UPS is 19-inch native)
- You have more than 24 ports of patching to manage
- You're adding 1U servers or NAS units that aren't 10"-compatible
The "best of both" pattern we see most often: a small 6U or 8U 10-inch cabinet for the gateway, Cloud Key, and a single switch — everything that runs 24/7 — and a separate 19-inch frame for the heavy switching and any 1U servers. The 10-inch cabinet sits with the residential gateway/ONT and the 19-inch frame lives wherever the noise is tolerable.
Cooling, power, cable management for a UniFi-only 10-inch rack
UniFi gear runs cool by hardware standards but not by enclosed-cabinet standards. A 12U 10-inch cabinet stuffed with an Express 7, a Lite-16 PoE, a USW-Ultra, and a Cloud Key will pull 30–60 W idle and spike higher under PoE load. That's not a thermal emergency, but you do need air to move.
The minimum: leave 1U of vertical gap above any device with a fan (Pro XG 8 PoE, Lite-16 PoE under heavy load), and don't blank-panel the entire front. Most 10-inch cabinets have vented top and bottom panels — keep them clear of the wall by 50–75 mm so convection works.
For power: a 6-outlet horizontal PDU in the bottom 1U is the cleanest pattern. Avoid the temptation to run a power strip up the side; the cables will fight you every time you pull a unit.
For Ethernet: keep patch cables under 1 m if you can. The single biggest source of "I can't close the rack door" frustration in a 10-inch cabinet is 3-meter patch cables that came in the box. Buy short patches, route up one side, down the other, and you'll keep the door swinging cleanly.
Common pitfalls
Mounting depth. A 10-inch cabinet's interior depth varies wildly — anywhere from 180 mm to 320 mm depending on the model. Devices like the Cloud Gateway Ultra are deep enough that they bottom out in the shallowest cabinets. Measure twice; some of our brackets ship with depth-adjustable tabs for this exact reason.
PoE budget. A Lite-8 PoE has a 52 W total PoE budget. That's two PoE+ APs and you're done. If you're powering four cameras and three APs from one switch, you need a Pro XG 8 PoE or a Lite-16 PoE — the bracket is the easy part; the budget math is what bites people.
Fan noise. Most UniFi homelab gear is fanless. The exceptions are Pro XG 8 PoE (small fan, audible in a quiet room), USW-Pro family (loud, 19" only), and any rackmount UPS. If you're putting the rack in living space, stay fanless or add 1U of acoustic foam between the noisy unit and the door.
Front-panel access. Don't mount your gateway at the bottom of the rack. The reset button is the one button you'll actually press at 11 p.m. when the WAN goes down, and you'll thank yourself for putting it at chest height.
Three sample UniFi 10-inch builds
Starter (6U, ~$300 in network gear, $80 in brackets)
- 1U — UniFi Express on a 10" Express & Gateway Lite mount with 2 keystones
- 1U — USW-Lite-8 PoE on a 10" Lite-8 PoE mini mount
- 1U — vented blank for airflow
- 1U — horizontal PDU (6-outlet)
- 2U — expansion / cable spool
Mid (8U, dual-switch setup with 10G uplink)
- 1U — UniFi Express 7 on a 10" Express 7 mount
- 1U — USW-Ultra on a 10" USW-Ultra modular mount
- 1U — USW-Lite-16 PoE on a 10" Lite-16 PoE mini mount
- 1U — Flex Mini with keystone breakouts on a 10" Flex Mini mount with 3 keystone jacks
- 1U — vented blank
- 1U — horizontal PDU
- 2U — expansion
Power-user 10-inch (12U, max-density, fanless)
- 1U — Cloud Gateway Fiber on a 10" Cloud Gateway Fiber mount (SFP+ from ISP ONT)
- 1U — Flex XG for the 10G core on a 10" Flex XG mount
- 1U — USW-Ultra (downlink)
- 1U — Lite-16 PoE (PoE distribution)
- 1U — Flex Mini 2.5G with keystone on a 10" Flex Mini 2.5G mount
- 1U — vented blank
- 1U — horizontal PDU
- 5U — expansion / future SFF host
You'll notice none of these builds include a USW-Pro-24. That's deliberate — the moment you need 24 ports of native PoE switching, you've outgrown the 10-inch envelope and a small 19-inch wall cabinet is the right answer. UniFi's homelab-friendly gear stops, roughly, at the Pro XG 8 PoE / Lite-16 PoE line. Above that, embrace the bigger frame.
Wrapping up
A 10-inch rack is not a compromise for a UniFi homelab — for most of the modern lineup, it's the better fit. The frame is cheaper, the footprint is friendlier, and the gear was designed to be the size it is. The brackets are the only piece Ubiquiti doesn't give you in the box, and that's where we come in.
If you want a starting point, the Mid build above is the one we recommend most often: an Express 7 for routing, a USW-Ultra for the fanless core, a Lite-16 PoE for ports, and a Flex Mini for stragglers. Eight U, no fans except the Pro XG (if you add one), and enough headroom to grow without ripping anything out.
If your build doesn't fit any of these patterns — or you have a UniFi device we don't have a bracket for yet — drop us a line. Half the brackets in our catalog started as a customer email that began with "I have this weird thing…"
