Transclosures are fabricated of not less than 11 gauge mild steel with the necessary angle and/or channel base frame. Units may also be constructed from 304 stainless steel, 316 stainless steel or aluminum. Each section shall be provided with 4 lugs for shipping and lifting the unit. All roofs are crowned with rain troughs between sections for proper water drainage. All corners are formed and welded which are then ground smooth. All hardware is cadmium plated and each compartment shall have hinged doors which shall be external panel mounted to the door and to the enclosure. The door is removable from the open position. All doors have stop latches and "Eberhard" or equal door locks and handles with 3-point latches. Enclosure is rated Nema 3R equivalent, which protects interior components from rain and weather.

NEMA 3R – Enclosures constructed for either indoor or outdoor use to provide a degree of protection to personnel against incidental contact with the enclosed equipment; to provide a degree of protection against falling dirt, rain, sleet, and snow; and that will be undamaged by the external formation of ice on the enclosure.

Multiple Bay Unit

Many colors are available which include Ansi 61 Gray, Ansi 70 Gray and Munsell Green to name a few. Paint colors can even be matched to existing units given the color or paint chip. All transclosures go through the same rigorous painting process. First the unit shall be thoroughly scraped and sanded to remove any burrs or welding spatter. The steel shall then be cleaned and phosphatized under 1800 PSI fluid pressure and treated at 258⁰F at a distance of 6 inches. Phosphoric acid shall be Fremont #658 applied at 3/4 of 1% by volume of water. Unit shall be allowed to dry for 30 minutes.

A red oxide modified alkyd primer shall be applied to unit in an even, thorough coat. Wet primer thickness shall be 3.0 - 4.0 mils. Dry primer thickness shall be 1.2 - 1.6 mils. A minimum period of one - two hours should be allowed for prime to dry before recoating.

A modified silicone acrylic alkyd enamel shall be applied a minimum of one - two hours after the primer has been applied to insure proper bonding. After the first coat is applied allow a minimum of 2 hours before recoating. After additional coat is applied allow a minimum of 2 hours before handling the unit. Minimum dry total thickness is 3.0 mils; desired dry total thickness is 3.5 mils.
