Middle Atlantic MRK-4442PRO – 44SP 42"D Multibay Rack PRO

Product Overview

The Middle Atlantic MRK-4442PRO is a 44-space, 42-inch-deep multibay configured rack with pre-installed cable management and power distribution, providing a deployment-ready AV equipment rack for commercial and enterprise AV system integration projects. This PRO-configured multibay rack ships with integrated cable management panels and power management accessories installed at the factory, reducing field labor and ensuring consistent rack organization across multi-unit deployments. AV integrators and system designers specifying pre-configured rack systems for large-scale commercial AV installations benefit from the MRK PRO series factory buildout.

Product Description

The MRK-4442PRO multibay rack provides 44 rack spaces at 42-inch mounting depth in a configured chassis that arrives with cable management and power distribution accessories already installed. The factory-installed cable management includes horizontal cable management panels positioned throughout the rack to maintain cable organization from initial equipment installation without requiring integrators to source and install these components separately. The integrated power distribution unit provides conditioned power delivery to installed equipment directly from the rack. The 42-inch mounting depth accommodates the full range of professional AV equipment including large AV processors, video distribution frames, multi-channel amplifiers, and AV-over-IP infrastructure. Heavy-gauge steel multibay frame construction provides structural integrity across a fully loaded 44-space rack. Standard EIA 19-inch mounting rails ensure universal equipment compatibility. The multibay chassis design supports configurations across multiple adjacent rack bays in larger system installations. The PRO designation differentiates this model from the standard MRK-4442 by including the pre-installed accessories that would otherwise need to be specified and installed separately in the field.

Technical Specifications

Frequently Asked Questions

What is included in the PRO configuration that is not in the standard MRK-4442?

The PRO model includes pre-installed horizontal cable management panels and a power distribution unit installed at the factory. The standard MRK-4442 is the base chassis without these accessories.

Does factory pre-installation of accessories affect equipment compatibility?

No. Pre-installed cable management panels and the PDU occupy specific rack spaces, but the remaining 19-inch EIA rail spaces remain available for all standard rackmount equipment.

What is a multibay rack configuration?

A multibay configuration allows multiple rack chassis to be joined side-by-side to create a larger equipment bay system. The MRK series supports these multi-unit configurations for larger AV system installations.

Is the 42-inch depth necessary for AV equipment?

The 42-inch depth accommodates deep AV infrastructure including large video processors, broadcast frames, and multi-channel amplifiers. If equipment depth is shallower, the ERK-4425-AV at 25-inch depth is an alternative to consider.

How much field labor does the PRO configuration save versus building out the base MRK-4442?

The exact labor savings depend on the installation scope, but integrators typically save 1-2 hours of rack preparation time per unit since cable management and power are already installed and positioned.

Where can I purchase the MRK-4442PRO?

The MRK-4442PRO is available from Creation Networks at creationnetworks.net.

Is the cable management configuration adjustable after delivery?

Yes. Pre-installed cable management panels are standard rackmount accessories and can be repositioned within the rack as required for the specific equipment layout.
