About Lowell Manufacturing LER-3522

Experience the pinnacle of electronic equipment organization with the LER-3522 35U 22" Depth Enclosed Stand Alone Floor Rack, a paragon of sturdiness and durability. Crafted from fully welded, certified U.S. steel, this robust floor rack boasts a 16-gauge frame and a 14-gauge base, both reinforced at load-bearing junctions to ensure unparalleled support and strength equivalent to 11-gauge steel.

The sleek black wrinkle powder epoxy finish not only adds to the aesthetic appeal but also enhances the rack's durability. The design features beveled edge corners on the front and rear, contributing to a refined and professional appearance while ensuring safety in your workspace.

Ventilation is thoughtfully integrated with front upper and lower vents, coupled with welded side panels that include additional vents at the top and bottom, promoting air circulation to keep your equipment cool and functioning optimally.

The frame of the LER-3522 is equipped with nutserts, ready to accommodate an optional surface-mount door that can swing either left or right, allowing for customization based on your spatial requirements (front door sold separately). The rear of the rack includes removable knockout panels with versatile EKOs for conduit and KOs for wireless antennae, ensuring seamless cable management and connectivity.

A standard recessed door with vents and a secure key lock system provides easy access while maintaining the security of your equipment. For those who prefer an alternative setup, the rear door can be omitted by specifying "LRD" in the model number.

The open access bottom of the rack includes a 10-32 threaded grounding stud, T-nuts for optional leg levelers, and pre-drilled holes for anchor bolts, facilitating stability and grounding for safety purposes. The cable management system is comprehensive, with combination knockouts in the top and rear, and a configurable top with closure panels for additional customization.

The rack rails are a testament to the product's reliability, featuring a pair of fully adjustable 11-gauge steel, 10-32 threaded rails on EIA spacing, complete with bi-directional numbered RU increments for precise equipment installation.
