2U rack depth adapter

This 2U rail depth adapter kit adds or subtracts 10 cm of mounting depth in a standard server rack. It suits installers who need to fit equipment that does not align with the existing rail positions.

Adjustable mounting depth

The bracket lets you move gear 4 inches forward or backward relative to the rails, solving clearance problems without replacing the rack. Two-post installations support 9 kg while four-post setups handle 59 kg.

Black steel bracket kit

The 90 mm wide by 113 mm long bracket mounts in front of or behind the rails and ships with cage nuts and screws for both the adapter and the mounting rail. It weighs 246.8 g and stands 25 mm high.
