Middle Atlantic STL FLR BOX Less COV KIT - 800LCK

Middle Atlantic 800LCK STL Floor Box Less Cover Kit

Overview

The Middle Atlantic 800LCK is a steel floor box kit supplied without a cover, designed for in-floor cable management and equipment mounting in rack-based AV, security, and structured cabling installations. The 800LCK addresses the specific scenario where an integrator sources or specifies the cover plate separately — whether to match an existing finish, accommodate a custom cutout, or phase the installation. This kit provides the box body and associated mounting hardware so the structural portion of the floor rough-in can proceed independently of cover selection.

Compatibility

The 800LCK is part of Middle Atlantic's STL floor box family. It is intended for use with compatible Middle Atlantic cover plates and inserts sold separately within the STL series. Confirm cover model compatibility against the STL floor box product family specifications before ordering, as cover fitment is series-specific. Suitable for integration into structured AV equipment rooms, security operations centers, and commercial facilities where flush floor-mounted connectivity points are required.

Installation Notes

Because this kit ships less cover, plan cover procurement before scheduling the finish phase of the installation — floor box body rough-in can proceed first, but the open box must be protected during construction. Verify local code requirements for in-floor electrical and low-voltage separation before positioning the box relative to power infrastructure. Confirm floor depth and construction type (concrete, raised access, wood subfloor) are compatible with the STL series mounting depth prior to ordering.
