Ace Backstage Co. BRK1028BBXW Polyurethane Encapsulated Extra Deep Full Stage Pocket Back Box

Polyurethane encapsulated back boxes are available to provide extra protection from incursion of moisture and water by sealing seams, knock-outs, and holes. Using our extra deep, double zinc plated back boxes (BRK8BBXW) a 1/16" thick jacket of polyurethane is applied to the exterior sides and bottom of the back boxes, permanently bonding with surfaces to form a moisture resistant seal. The polyurethane back box provides protection against harsh climate, chemicals, impact and abrasion. All polyurethane back boxes will have a model number suffix of "W".

ACE polyurethane encapsulated Extra Deep Back Boxes (#BRK1028BBXW and #BRK1048BBXW) are slightly deeper (8”) as compared with Standard #BBX Series Back Boxes (6”) and may be used exclusively with ACE Full and Double Wide Stage Pockets. The #BRK1028BBXW and #BRK1048BBXW polyurethane encapsulated Extra Deep Back Boxes are welded 14 gauge steel with a protective cover that is discarded when the pocket body is finally installed. The box and cover have a clear zinc corrosion resistant finish. A 1/2” mounting flange is predrilled to mate with the pocket body flange. The pocket body assembly is 4.5” deep and the extra deep back box is 8” deep providing a 3.5” work clearance in the bottom of the back box (ideal for feed thru or distribution junction).

The clearance volume (volume between bottom of pocket body and bottom of the extra deep back box) is 338 cubic inches in the #BRK1028BBXW and 613 cubic inches in the #BRK1048BBXW. ACE polyurethane encapsulated Extra Deep Back Boxes come with standard Electrical Conduit Combination 1/2”, 3/4”, 1”, and 1-1/4” Knock Outs, 4 places typical on opposing sides and Electrical Conduit Combination 1/2”, 3/4”, 1”, and 1-1/4” Knock Outs, 2 places typical on one side.
