OUR PART #  LER-4427

The LER is an E.I.A. compliant rack (UL Listed, Standard 1678) that offers solid structural support and code compliance to mount and secure 19" wide electronic equipment. Rack is fully welded 16-ga. steel with a 14-ga. steel bottom and reinforced at all load-bearing junctures for strength equivalent to 11-ga. steel.

Rails feature a dual-hole pattern and are installed with the tapped (10-32) side in position.

Clearance from rails to flush outside of frame is 1.75" (2.5" from rail to inside of optional surface-mount front door).
