Middle Atlantic Base Coupling - AL3301

Middle Atlantic AL3301 Base Coupling

Overview

The Middle Atlantic AL3301 is a base coupling designed to mechanically join adjacent AL-series rack enclosure sections at the base, creating a unified floor-standing assembly. In rack deployments where multiple enclosures are placed side by side — AV equipment rooms, security head-end closets, or structured cabling installations — individual cabinets can shift or rack-mount hardware can misalign over time without a positive mechanical connection at the base. The AL3301 closes that gap by coupling enclosure bases so the assembly behaves as a single rigid unit. For anyone building out a multi-bay Middle Atlantic AL-series installation, this coupling is the correct hardware to specify rather than leaving bays free-standing.

Compatibility

The AL3301 is designed for use with Middle Atlantic AL-series rack enclosures. If you are working with a different Middle Atlantic enclosure family — such as the BGR, PD, or SRS series — verify series-specific coupling requirements with the enclosure documentation before ordering, as base coupling hardware is not universally interchangeable across enclosure lines. When planning a multi-bay AL-series deployment, also review rack power distribution options to complete the installation.

Installation Notes

Base couplings are typically installed during initial enclosure placement before equipment is loaded. Confirm the floor surface is level before coupling enclosures — an uneven base will transfer stress to the coupling hardware and may misalign rack-unit positions across bays. Consult the AL-series enclosure installation guide for torque specifications and hardware orientation before final fastening.
