About Lowell Manufacturing LSER-4027

Take your data center or server room organization to the next level with the LSER-4027 40U Seismic Rack. This robust and reliable rack is designed with a 27" depth and adjustable rails, providing ample space and flexibility for your electronic equipment.

Constructed from fully welded, certified U.S. steel, this sturdy rack boasts a 16-gauge frame and a 14-gauge base, reinforced at all load-bearing junctions for maximum support. The strength of this rack is equivalent to 11-gauge steel, ensuring it can withstand seismic activities and protect your valuable IT equipment.

The rack is finished with a black wrinkle powder epoxy, giving it a sleek and professional appearance. The front of the rack features upper and lower vents for optimal airflow, and is equipped with nutserts ready for the addition of an optional surface-mount door, available for separate purchase.

At the rear, the rack includes two removable knockout panels above the door, with combination EKOs for conduit (1/2"-3/4" and 1"-1-1/2") and KOs for wireless antennae (1/2"). Two removable blank project panels are also included below the door.

The sides of the rack are welded and feature vents at the top and bottom for additional airflow. The bottom of the rack is open access, with a welded bracket in each corner for anchor bolt installation.

The top of the rack is configurable, with a 7U opening featuring riveted 10-32 threaded rails on 19" E.I.A. spacing. It includes two black closure panels (3U, 4U) which can be replaced with optional 19" panels.

The rack's rails are fully adjustable, made from 11-gauge steel with bi-directional numbered RU increments. The rack is EIA/TIA compliant, RoHS compliant, and UL 2416 Listed in the U.S. and Canada.
