1U Depth Extender for Server Racks

This two-pack adds 100 millimetres of mounting depth to a standard 1U space. Each bracket is built from 1.4mm carbon steel and finished in black. The kit includes four sets of M6 screws and cage nuts for installation. The extenders mount directly to the rack rails to reposition equipment.

Suits installers needing extra depth in a 1U slot

Network engineers can recess switches or patch panels by four inches without changing the rack. The steel construction conducts heat away from mounted devices. Not suited for loads above ten pounds per pair or ninety pounds per four brackets. Buyers who need deeper extension or heavier capacity should look at other solutions.

100 millimetre depth increase per bracket

The single specification that decides fit is the 3.94 inch extension. Verify that your equipment and rack rails accept this additional depth before purchase. The brackets support 10-32 and 12-24 thread patterns. Each unit weighs 0.168 kilograms.

Questions about this item

What rack depth and thread types does the 100 mm extender fit?

The extender adds 100 mm (3.94 in) of depth and mounts in standard 1U openings using the included M6 cage nuts; the kit also supplies 10-32 and 12-24 screws for equipment rails.

Which step do installers most often miss when fitting the carbon-steel brackets?

Forgetting to cage-nut all four corners of each 1U bracket before tightening the equipment screws, which leaves the 1.4 mm steel flexing under load.

When should the M6 cage nuts and screws be checked or replaced?

Inspect the cage nuts and screw threads whenever equipment is removed or after any rack relocation; replace any that show stripped threads or corrosion to keep the 90 lb four-bracket rating intact.
