About Lowell Manufacturing LER-4022

It's the LER-4022 40U 22" Depth Enclosed Stand Alone Floor Rack, a robust and versatile solution for your electronic equipment storage needs. This floor rack, meticulously crafted from fully welded, certified U.S. steel, boasts a 16-gauge frame and a 14-gauge base, offering strength equivalent to 11-gauge steel. Reinforced at all load-bearing junctions, it provides robust support for your equipment.

The rack features a sleek black wrinkle powder epoxy finish, adding a touch of elegance to its sturdy build. It's designed with beveled edge corners on both the front and rear for a refined look. The front of the rack includes upper and lower vents, ensuring optimal airflow for your equipment.

The LER-4022 comes with frame nutserts, ready to accommodate 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, offering secure storage for your equipment. The rear door can be omitted by adding the "LRD" (less rear door) suffix in the model number.

The sides of the rack are welded, featuring vents at the top and bottom for enhanced ventilation. The bottom of the rack 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 LER-4022 also offers excellent cable management, with combination knockouts in the top and rear. The top of the rack is configurable, featuring 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.

The rack comes with a pair of 11-gauge steel 10-32 threaded rails, fully adjustable and featuring bi-directional numbered RU increments. The black finish of the rails complements the overall aesthetic of the rack.

For quick installation, the rack includes black pilot point screws with captive washers. The LER-4022 is EIA/TIA compliant, RoHS compliant, and UL 2416 Listed in the U.S.A. and Canada, ensuring it meets the highest standards of quality and safety.
