About Lowell Manufacturing LER-4422

Enhance your equipment storage with the LER-4422 44U 22" Depth Enclosed Stand Alone Floor Rack. This robust storage solution is designed with a fully welded 16-gauge steel frame and a 14-gauge base, reinforced at all load-bearing junctions for maximum support and durability. The strength of this rack is equivalent to 11-gauge steel, ensuring it can handle heavy equipment with ease.

The rack features a sleek black wrinkle powder epoxy finish, adding a professional touch to any setting. Its design includes beveled edge corners on both the front and rear for a refined look. The front of the rack boasts upper and lower vents for optimal airflow, ensuring your equipment stays cool.

The frame of the LER-4422 comes with nutserts ready for the addition of an optional surface-mount door, which can swing either left or right. The rear of the rack includes removable knockout panels above and below the door, with combination EKOs for conduit (1/2"-3/4" and 1"-1-1/2") and KOs for wireless antennae (1/2").

The rack's standard model includes a recessed door with vents and a key lock for secure storage. If a rear door is not required, it can be omitted by adding the "LRD" suffix to the model number. 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 and includes a 10-32 threaded grounding stud in the corner, 3/8"-16 threaded T-nuts for optional leg levelers, and holes for anchor bolts. The opening measures 17.88"D x 19.94"W, providing ample space for cable management.

The top of the rack is configurable and features a 7U opening with 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 for customization.

The LER-4422 44U rack comes with one pair of fully adjustable 11-gauge steel 10-32 threaded rails on E.I.A. spacing, with bi-directional numbered RU increments. The black finish of the rails matches the overall aesthetic of the rack.
