Desk Screen Clamps and Fixings: Which One Do I Need?
Posted by Panelscreens on 4th Oct 2026
Most desk screens fix to the desk with a clamp, but desks vary: some are thin, some sit on deep leg frames, some are bench desks with no back edge at all. Choosing the right fixing is the difference between a screen that fits in five minutes and one that goes back in the box. This guide explains each fixing we offer and how to pick the right one.
The short answer
- Standard office desk: 28mm desk clamp.
- Thick desk, or a leg frame at the back: 50mm or 70mm desk clamp.
- Back-to-back bench desks: bench bracket.
- Monitor arms on the back edge: floating bracket.
- Pedestal or cupboard: 30mm side fixing.
- Can't clamp at all: freestanding feet.

How to measure your desk
Measure the thickness of the desk top at the back edge, where the screen will go. If there is a metal frame or modesty panel running along the back, measure the desk and frame together, because the clamp needs to fit over both. Then pick the clamp whose range covers that number.
The fixings explained
28mm desk clamp
Our standard fixing. It fits desk tops 12 to 28mm thick, which covers most office desks, and has an adjustable 16mm bolt. Supplied as a set of two metal clamps.
50mm and 70mm desk clamps
For thicker desks, or where the clamp has to reach over a leg frame. The 50mm clamp fits 20 to 50mm and the 70mm clamp fits 40 to 70mm. Both have a fixed 30mm bolt.
Bench bracket
Bench desks put two desk tops back to back with a small gap between them. The bench bracket sits in a 30mm gap and holds the screen in line with the underside of the desk tops, so one screen divides both people. See our bench and desk divider screens.
Floating bracket
If monitor arms are clamped to the back edge of the desk, there is no room for a screen clamp. The floating bracket fixes under the desk top instead and holds the screen clear of the monitor arms.
30mm side fixing
For fixing a desk screen to the side of a pedestal, cupboard or desk end where there is only a small gap to work with.
Freestanding feet
Metal feet with a W200 x D100mm base and a 100mm spigot. The screen simply stands on the desk top, with no clamping. Useful for glass desks, hot desks, or anywhere you don't want fixings. They cost +£27.99 per screen, ex VAT.
Sit-stand and height adjustable desks
On a height adjustable desk the screen must move with the desk top, so always use a desk clamp, never freestanding feet on a separate surface. Check the clamp sits clear of the lifting columns and cables along the back edge.

FAQs
What size desk clamp do I need?
Measure the thickness of your desk top, plus any frame you need to clamp over. The 28mm clamp fits desk tops 12 to 28mm thick, the 50mm clamp fits 20 to 50mm and the 70mm clamp fits 40 to 70mm.
Can I fit a desk screen to a bench desk?
Yes. Bench brackets sit in the 30mm gap between back-to-back desk tops, so one screen divides both desks.
Will a desk screen work with monitor arms?
Yes. Choose the floating bracket, which fixes under the desk top and leaves room for monitor arm clamps.
Do I need tools to fit desk screen clamps?
No special tools. The clamps tighten by hand or with the key supplied [confirm], and freestanding feet need no fixing at all.
Are the clamps included in the price?
Desk clamps and brackets are included at no extra cost on most of our screens. Freestanding feet cost +£27.99 per screen, ex VAT.
