Middle Atlantic AL5256-Z Mousehole Device Plate
Overview
The Middle Atlantic AL5256-Z is a mousehole device plate designed to provide a clean, managed cable pass-through point within rack enclosures and cabinets. It addresses a common integration problem: routing power, signal, or data cables between rack sections or through a panel without leaving open gaps that compromise cable management, airflow control, or enclosure aesthetics. The AL5256-Z installs into a standard rack unit opening, allowing cables to pass through a defined aperture rather than an unfinished cutout.
Compatibility
Designed for use with Middle Atlantic rack enclosures and cabinets that accept standard rack-mount accessory plates. Verify the rack unit height and mounting hole pattern against your specific enclosure before ordering — Middle Atlantic uses consistent rail spacing across their rack mount accessory lines, but confirm the AL5256-Z panel dimensions match your cabinet series. Suitable for AV, security, and IT rack builds where structured cable management is required.
Installation Notes
Mount into an available rack unit space using standard rack screws. Route cables through the mousehole aperture before final cable dressing. Keep the plate clear of high-heat cable bundles to maintain enclosure airflow paths. If your installation requires brush inserts or grommets for additional cable protection or dust control, verify whether those accessories are included or must be sourced separately — no package contents data is available in evidence for this SKU. For broader infrastructure planning, consult a rack enclosure selection guide to confirm panel compatibility before installation.
