Middle Atlantic MRK-4026LRD – 40SP Multibay MRK Rack 26"D with LRD

Product Overview

The Middle Atlantic MRK-4026LRD is a 40-space multibay MRK rack with a 26-inch depth and Middle Atlantic's Lever-Release Door (LRD) system, designed for high-density AV equipment rooms that require both structural capacity and fast door access. The MRK series provides a gangable rack solution optimized for multibay AV system deployments in broadcast, corporate, and live event production environments. The LRD mechanism allows single-handed door release without tools, enabling quick access to equipment for maintenance or reconfiguration. The 26-inch depth is suited for AV processing equipment, power conditioning, and distribution gear that does not require full 30-inch depths.

Product Description

The MRK-4026LRD is a production-grade rack frame for integrators and facility managers who build and maintain large AV infrastructure systems. At 40 rack units, this frame accommodates full AV signal chains including video switchers, audio DSPs, amplifiers, network switches, and power distribution in a single multibay bay. The 26-inch depth is a deliberate specification for installations where floor space economy matters and the equipment inventory does not require deeper frames. The LRD system is one of the features that distinguishes the MRK series in operational environments: technicians can open and close the rack door with one hand and without any tools, a meaningful efficiency gain in high-access environments. The multibay gangable design allows the MRK-4026LRD to be coupled with adjacent MRK units, sharing structural support across the row and enabling consistent cable management and aesthetic uniformity across multi-bay deployments. Middle Atlantic MRK frames are built from heavy-gauge steel with a welded base, supporting the concentrated loads common in fully populated AV racks. The frame accepts standard 10-32 and 12-24 threaded accessories across Middle Atlantic's accessory catalog. Available through Creation Networks at creationnetworks.net.
