Middle Atlantic BS-MRK – Inner Platform Base for MRK Racks

Product Overview

The Middle Atlantic BS-MRK Series is an inner platform base for MRK Series equipment racks that creates a load-bearing surface flush with the bottom rackspace. It gives integrators a stable platform for supporting heavy equipment and mounting electrical boxes inside the rack footprint. Built from steel with a black finish, the series is offered in six depths — 26, 27, 31, 32, 36, and 42 inches — to match the full range of MRK rack depths.

Product Description

Heavy amplifiers, UPS units, and power equipment often exceed what standard rack shelves should carry, and the BS-MRK Series solves that problem at the bottom of the enclosure. The platform installs inside the MRK rack and sits flush with the bottom rackspace, so the heaviest components in the system rest on a supported steel surface rather than on rail-mounted hardware. The base also serves as a practical mounting point for electrical boxes, keeping power distribution and junction hardware organized within the rack during commercial AV installation. A center opening in the platform preserves cooling air flow from below and provides a pass-through for cable entry, so the base supports thermal management and cable routing rather than blocking them. Sturdy steel construction with a black finish matches the MRK enclosure for a consistent equipment room appearance. With six depth options from 26 to 42 inches, the correct model can be matched to any MRK rack depth in a deployment. Browse compatible racks, rackshelves, and power accessories in the Middle Atlantic collection at Creation Networks to complete the build.

Frequently Asked Questions

Which racks is the BS-MRK Series compatible with?
The BS-MRK inner platform base is designed for Middle Atlantic MRK Series racks. Select the model that matches your rack depth: 26, 27, 31, 32, 36, or 42 inches.

What is an inner platform base used for?
It creates a supported surface flush with the bottom rackspace, so heavy equipment such as amplifiers and UPS units can rest on the base of the rack instead of on rail-mounted shelves. It also serves as a mounting platform for electrical boxes.

Does the platform block airflow into the rack?
No. The platform includes a center opening that preserves cooling air flow from below and can also be used for bottom cable entry.

Can cables enter the rack through the base?
Yes. The center opening doubles as a cable entry point, which is useful when power and signal cabling is routed under the floor or up through the rack base.

Does the base change the rack's footprint?
No. The platform fits inside the rack, so it adds load support without increasing the floor space the enclosure requires.

Is the BS-MRK covered by a warranty?
