Middle Atlantic MV-ISO-42 – Rack Isolation Kit for 42" Deep MRK/VRK

Product Overview

The Middle Atlantic MV-ISO-42 is a rack isolation kit that electrically isolates select rack models from riser base systems and the floor. It is designed for 42-inch deep MRK, VRK, and VMRK Series equipment racks, where a dedicated isolated ground scheme or telecom-grade grounding plan requires the rack frame to be decoupled from the building structure. The kit uses tough, non-conductive polycarbonate material and includes the isolation hardware needed for installation.

Product Description

In broadcast plants, data centers, and other facilities with engineered grounding systems, an equipment rack that contacts a steel riser base or conductive flooring can create unintended ground paths. Those stray paths defeat single-point grounding designs and can introduce ground loops that show up as hum, noise, or data errors in sensitive AV and IT systems. The MV-ISO-42 rack isolation kit addresses this at the mechanical interface: non-conductive polycarbonate isolation pieces install between the rack and the riser base system, breaking electrical continuity while preserving a secure mechanical attachment. The kit supplies eight pieces of 4-inch long isolation material along with the matching isolation hardware, sized to suit 42-inch deep MRK, VRK, and VMRK racks from Middle Atlantic. Polycarbonate was chosen for its dielectric properties and impact toughness, so the isolation layer holds up under fully loaded rack weights. For integrators standardizing on Middle Atlantic riser base systems, this kit is the documented method for isolating compatible rack models as part of an isolated ground installation. Confirm rack model and depth before ordering; this version is specific to the 42-inch deep frame sizes.

Key Features

• Electrical Isolation — Electrically isolates select rack models from riser base systems and the floor to support isolated ground installations.
• 42-Inch Deep Rack Compatibility — Works with 42-inch deep MRK, VRK, and VMRK Series equipment racks.
• Non-Conductive Polycarbonate — Tough polycarbonate material provides dielectric separation with the strength to support loaded racks.
• Complete 8-Piece Kit — Includes eight pieces of 4-inch long isolation material plus the required isolation hardware.
• Ground Loop Prevention — Breaks unintended ground paths between the rack frame and building structure that can cause hum and noise in AV systems.
