Desk Corner Sleeve DSKCRNRSLV

The StarTech Desk Corner Sleeve DSKCRNRSLV clamps onto a 90° L-shaped desk corner to add 25 x 13.1 in of surface area for a keyboard and mouse. It ships fully assembled for immediate use in office or home environments. The gray finish blends with typical workstation aesthetics.

Check desk thickness and corner angle

Verify your desk corner forms a 90° angle and measures between 0.5 and 1.5 in thick to accept the clamp. Ensure the corner area is clear of obstructions that would prevent the low-profile clamp from seating properly. Confirm you have a screwdriver available if you choose the wood-screw mounting option instead of the direct clamp method.

Suits users extending L-shaped desk workspace

This sleeve suits anyone needing extra keyboard and mouse space on a compatible L-shaped desk to improve wrist support and monitor distance. It is not for buyers with straight desks, corners other than 90°, or desk thicknesses outside the 0.5 to 1.5 in range. Users requiring a larger platform than 25 x 13.1 in should look at a different solution.

Questions about this item

Does the StarTech DSKCRNRSLV ship with everything needed to mount it on a 12 mm thick desk, or must I buy extra hardware?

The sleeve arrives fully assembled and includes both the clamp and wood screws for desks between 127 mm and 381 mm thick, so no extra hardware is required.

Should I choose the 635 mm × 332 mm Gray sleeve or a different size for a 90° corner desk?

Only the 635 mm × 332 mm Gray model is offered; it is designed specifically for 90° L-shaped corners and adds 25 × 13.1 in of keyboard and mouse space.

How much extra room for a keyboard and mouse does the 25 × 13.1 in surface actually give once clamped on my desk?

The extender adds a 635 mm × 332 mm platform that supports a full-size keyboard and mouse while keeping wrists level, improving comfort at the corner.
