Choosing the right 19-inch network cabinet
A 19-inch cabinet accommodates standard 19-inch rack-mounted equipment, but the right choice depends on your rack height, equipment depth and installation space. Start with the equipment you need to house, and leave room to work around it.
Work out how much rack space you need
Add up the rack units required by switches, patch panels, shelves, PDUs and other mounted equipment. Allow for the height of anything sitting on a shelf, and leave spare capacity if your network is likely to grow. A rack unit (1U) is 44.45mm high.
Choose the depth that fits your equipment
The quoted cabinet depth is an external dimension, not the usable equipment depth. Measure the deepest device from its front mounting ears to the back of its chassis, then allow for plugs, connectors, cable bends and anything that projects towards the door. Use the recommended equipment depth to plan a comfortable fit.
Check the wall before fitting
Check the total installed weight, including the cabinet itself, equipment and accessories. Our P Series cabinets are rated for up to 60kg of equipment, but the wall and fixings must safely support the complete installation. Wall fixings are not supplied because the correct type depends on the wall construction.

19-inch Data Cabinets: Your Questions Answered
Practical advice on choosing a 19-inch rack, calculating rack space, checking cabinet depth and deciding between assembly options.
What does “19-inch” actually mean on a rack cabinet?
It describes the rack-mounting format, not the external width of the cabinet.
Standard 19-inch equipment has mounting ears designed for the corresponding 19-inch rack profiles. The equipment front panel is approximately 19 inches wide across the mounting ears, while the cabinet itself must be wider to accommodate its frame, door, side structure and internal clearances.
How do I work out how many U of cabinet space I need?
Add together the rack space required by everything you intend to mount: patch panels, switches, shelves, horizontal PDUs, cable managers and any other rack-mounted equipment.
Then consider equipment sitting on shelves. The shelf may occupy 1U at its mounting position, but the equipment resting on its platform may extend through that U and require additional clear space above it.
Finally, leave some room for growth if possible. A cabinet calculation that arrives at exactly 12U for a 12U cabinet is mathematically impeccable and operationally rather optimistic.
What is the difference between nominal cabinet depth and usable internal depth?
The nominal cabinet depth describes the overall depth class of the enclosure — for example 300mm, 450mm, 550mm or 600mm.
The usable internal depth is the space available inside the cabinet after allowing for the front door, rear structure and other parts of the enclosure. It is therefore smaller than the nominal depth.
Approximate usable internal depths are 250mm for a 300mm cabinet, 400mm for a 450mm cabinet, 500mm for a 550mm cabinet and 550mm for a 600mm cabinet.
Usable internal depth should not automatically be treated as suitable equipment depth because connectors, cable bends, rail position and front-door clearance also require space.
Should I leave spare U for future expansion, and how much?
Yes, where space and budget allow.
There’s no universal percentage because some installations are effectively finished on day one while others acquire new equipment regularly. Even one or two spare U can be valuable in a small installation; more is sensible if you already expect the network to grow.
Buying a cabinet in which the final available U is occupied during the initial installation is wonderfully efficient — right until somebody buys one more switch.
In extremis, you can then find yourself replacing an entire wall-mounted cabinet because a device 44.45mm high has appeared.
A little unused rack space is usually much cheaper than replacing the enclosure later.
What is the difference between a ready-assembled and flat-packed 19-inch cabinet?
Functionally, very little once both are assembled correctly.
The ready-assembled cabinet arrives built, with the door, side panels, mounting profiles, cable-entry covers, locks and bonding components already fitted. The flat-packed version arrives as the same basic cabinet construction in pieces and needs assembling before use.
One practical advantage of the flat-packed version is access. In pieces, it can pass through openings that a fully assembled cabinet may not. A loft hatch is a good example: the finished cabinet might have no realistic chance of getting through it, while the individual panels can be carried up and the cabinet assembled in position.
You’re choosing between factory assembly and doing the assembly yourself, not between two different grades of cabinet.
The flat-pack version hasn’t sacrificed structural integrity for the privilege of fitting into a flatter cardboard box. Once assembled correctly, it’s intended to perform the same job as the ready-assembled version.
Are wall fixings supplied, and what sort of fixings should I use?
Wall fixings are not supplied.
That is deliberate. A fixing suitable for solid brick may be completely wrong for blockwork, timber framing or plasterboard.
Choose fixings suitable for the actual wall construction and the complete loaded weight of the cabinet, not just the empty cabinet. If you are not sure what the wall can safely carry, get someone competent to assess it before mounting the cabinet.
How much weight must the wall and its fixings actually support?
The whole lot.
If the cabinet weighs 20kg and you put 50kg of equipment inside it, the wall is supporting approximately 70kg. Describing the equipment as being within a 60kg cabinet rating doesn’t make the cabinet's own 20kg disappear.
And the cabinet rating tells you what the cabinet can carry. It doesn’t certify the brick, block, timber, plasterboard or whatever fixing system sits between the cabinet and the building.
Wall capacity and cabinet capacity are separate questions. Both need satisfactory answers.
