I have several of these weatherproof enclosures available from the electric utility industry. Minimum internal dimensions are approximately 13" x 7-1/2" x 6", weight is ~10lbs. The enclosure is made of a very durable white plastic. The front of the enclosure opens 180+° on the long edge & has an aluminum panel inside which has a variety of threaded holes for attaching comms equipment. The door incorporates a continuous rubber O-ring seal, and a stainless steel spring loaded latch which will accommodate a pad lock. The back of the enclousre has an array of bosses with integrated stainless steel threaded inserts for (6-32 or 8-32, I don't recall) machine screws (included). All I/O connections are through the bottom of the back which include a PolyPhaser surge arrestor (N female each side), vent, grounding lug, sheet aluminum grounding plate, and a 7 pin male Canon connector. There is an integraged aluminum U bracket which extends above and below the top and bottom edges of the enclouse for mounting to a utility pole. Four 1/4"-20 stainless steel bolts with O-ring seals attach the plastic housing to the aluminum U bracket. These are all removed from service and show some cosmetic evidence of that.
