Electronic Enclosures

Rack/Enclosure Design Features

Electronic enclosures are racks or cabinets designed to hold electronic equipment, such as data servers, control panels, and communication systems. They protect the equipment’s components from damage and prevent electrical shock caused by direct contact with them. Ours are made from extruded aluminum alloys and rated for different protection levels in a variety of applications and environments. 

Innovative Electronic Enclosures From A & J Manufacturing

A & J Manufacturing offers light-, medium-, and heavy-duty electronic equipment racks/enclosures with a large variety of equipment installation assemblies. Our unique family of proprietary aluminum extrusions makes our products modular, versatile, and high-performing. A & J enclosures incorporate a “bolted-together” design that allows for easy disassembly and reassembly. Our basic installation kits are shock- and vibration-qualified and interchangeable between different rack/enclosure configurations.

Design Features

  • Lightweight – aluminum / modular / bolted-together
  • No weld joints
  • EIA / STD mounting pattern available (front, rear & internal)
  • Easily disassembled and re-assembled
  • T-slot design allows for infinite vertical equipment positioning
  • No tooling required
  • Any size (height, width, depth) can be specified
  • On-site engineering services for custom applications
  • Full compliment of equipment mounting kits; plus cooling systems, filters, PDUs, slides and other accessories
  • Can be converted to EMI / FRI in field

Technical Design of our Racks

Our racks/enclosures feature 19-inch wide front and rear panels with front RETMA rails that have standard EIA panel mounting hole patterns and vertical T-Nut slots and two backup rails that have T-Nut slots located in the rear. A rear EIA hole pattern is optional.

  • The use of the T-Nut slot allows for infinite vertical adjustments without the need for drilled mounting holes. The T-Nut slot dimensions from the front to rear and side to side are maintained throughout the standard series of light-, medium- and heavy-duty configurations to facilitate the interchangeability of installation assemblies.
  • The RETMA Rail EIA holes have stainless steel threaded inserts that may be removed and replaced when the insert becomes stripped or worn.
  • RETMA rails and backup rails enable the rack/enclosure to be configured at any time to meet EMI/RFI requirements.
  • An X brace is included as a standard feature in all delivered racks/enclosures. It provides torsional stiffness and keeps the vertical frame members from bowing.
  • Our COTS standard racks are recognized as a military standard. Many products have been assigned National Stock Numbers.
  • If multiple racks are required, joining kits are available for multi-bay configuration.

Bolted Construction

The bolted-together design enables the rack to be disassembled for passage through narrow openings and passageways and around tight corners. The rack/enclosure may be reassembled and still maintain its original structural integrity. When reassembling, the following types of tools and torque values should be observed together with an application of component adhesive to the joining bolts.
