To ensure a strong and rigid construction, these enclosures are manufactured from 0.125" 5052-H32 marine grade aluminum.  They may also be ordered in 14 gauge (0.075") type 304 stainless steel. All external hardware is stainless steel to provide a high degree of protection from corrosion. Internal hardware is stainless steel or zinc plated, meeting Fed. Spec. QQ-Z-235C Type 1.

Smooth and free of blow holes, flaws and imperfections, all seams are continuously welded (GTAW) or sealed with G.E. Silicone Sealant (or equivalent) in the interior or on the exterior.


The enclosure has a crowned top to prevent water accumulation.

Two lifting lugs are provided.

For NEMA 3R applications, the door has a louvered vent with retainer for a removable filter. Disposable paper filters are provided.

The enclosures are equipped with bracket provisions for rigid mounting of an optional rack frame assembly for the mounting of components.

There is a provision for mounting a switch for a light or interlock that would be activated by opening the door.

The enclosure door openings are double flanged on all four sides. This feature not only provides additional strength, but prevents dirt and liquids from dropping into the enclosure when the door is opened.

All surfaces, edges and openings are smooth and burr-free for worker safety and equipment protection.


The cabinet is designed so that the leaves of the hinges are not exposed, making the hinges tamper-proof and presenting a neat and clean appearance. The cabinet doors are attached to the body of the enclosure by means of a 0.075" stainless steel piano-type hinge. It is bolted to the door and to the cabinet with 1/4-20 stainless steel carriage bolts and Nylock nuts. Further, the 0.25" stainless steel hinge pin is welded on the top to prevent tampering.

The door is sealed with a closed cell neoprene gasket bonded to the inside of the door with an oil resistant adhesive.

The three-point latching mechanism is designed with a heavy duty 3/4" stainless steel handle. This handle operates the 3/16" thick cam and two push rods made from 1/4" x 3/4" aluminum bar. The push rods are twisted outward and have two 7/8" nylon rollers on the end of each rod to provide a smooth operation and secure seal to the enclosure.

Provision is made for padlocking the handles. On NEMA 3R enclosures, a deadbolt-type Corbin 1548-1 or equivalent lock with two keys is standard.

The enclosure has an interior door restraint that prevents the door from moving in windy conditions. The restraints hold the doors in three positions—95°, 120° and 180°.


Standard enclosures are provided with a smooth and uniform, natural aluminum finish (Mill finish to Fed. Spec. QQA-250/8).

Painted finishes are available. Supply a sample of paint color (chip) or a paint number in compliance with MIL standard 595.

Powder coat finishes are also available.


The enclosure is designed as a pad mounting unit, as shown in the diagrams below.

Alternate Specifications:

For NEMA 4 and 4X style applications, there are no vents or locks on the main door. All through holes are sealed. Provision is made for padlocking the door handle.
