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.


For interior flexibility, 20" and 26" high enclosures are equipped with "C" mounting channels on each side wall for the mounting of shelves or panels.

The enclosure door opening is 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 door is attached to the body of the enclosure by means of a continuous 0.075" stainless steel, piano-type hinge on the right side. 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 door lock is Corbin #R357SGS or equivalent, with a pivoting keyhole cover.


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.

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


The mounting flanges have holes for wall mounting and vertical slots for pole mounting using banding.
