Ace Backstage 102BBXW Back Box with Polyurethane Encapsulation for Full Pocket

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 standard double zinc plated back boxes (BBX) 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".

The #102BBXW, #103BBXW, and #104BBXW 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 (#025BBX Back Box has a 7/16" mounting flange also predrilled to mate with Mini pocket body flange). The pocket body assembly is 4.5” deep and the back box is 6” deep providing a 1.5” 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 back box) is 260 cubic inches in the #104BBXW, 144 cubic inches in the #102BBXW, and 92 cubic inches in the #103BBXW. ACE polyurethane encapsulated Back Boxes come with standard Electrical Conduit Combination 1/2”, 3/4”, 1”, and 1-1/4” Knock Outs, 2 places typical on opposing sides and Electrical Conduit Combination 1/2” and 3/4” Knock Outs, 1 place typical on opposing sides.

Features:

• MOISTURE PROTECTION: ACE polyurethane encapsulated back boxes are made from our standard double zinc plated back boxes (BBX). A 1/16” thick jacket of polyurethane is applied to the exterior sides and bottom of the Back Boxes. The polyurethane encapsulates and permanently bonds with the back box surfaces providing protection against the harsh climate, chemicals, accidental impacts, and abrasions.
• CLEARANCE VOLUME: Standard Stage Pocket body assemblies are 4.5" deep while the Back Box is 6" deep providing 1.5" work clearance in the bottom of the Back Boxes, making them ideal for feed thru or distribution junctions. Clearance volumes for individual Pocket/Back Box assemblies are as follows:
  • #102BBXW Back Box with Full Pocket Clearance volume: 144 Cubic Inches
  • #103BBXW Back Box with Half Pocket Clearance volume: 92 Cubic Inches
  • #104BBXW Back Box with Double Wide Pocket Clearance volume: 260 Cubic Inches
• DURABLE CONSTRUCTION: ACE polyurethane encapsulated Back Boxes (#BBXW) are made from tough, welded 14 gauge steel (.071" thick).
• EASY INSTALLATION: ACE polyurethane encapsulated Back Boxes are easily installed into the floor or stage in a few steps. First make the cutout in the floor/stage. Second, securely brace the Back Box into the floor and be sure to provide support equal to the floor loading requirements, accounting for any height offset required for the finished floor. Third, attach any standard electrical conduit to the back box on any side via the combination knock outs. Fourth, secure Stage Pocket to Back Box using mating screw holes provided on the Stage Pocket flange and the Back Box flange.
• DURABLE FINISH: ACE Back Boxes have a clear zinc corrosion resistant finish (before applying the Polyurethane Encapsulation).
• ELECTRICAL KNOCKOUTS: ACE polyurethane encapsulated Back Boxes come with standard Electrical Conduit Combination Knockouts. 1/2", 3/4", 1", and 1-1/4" Knock Outs 2 places typical on opposing sides. 1/2" and 3/4" Knock Outs 1 place typical on opposing sides.
• PROTECTIVE COVER: Included with the polyurethane encapsulated Back Box(es) is a protective cover with a clear zinc corrosion resistant finish. This cover maintains a clean Back Box until the pocket is finally installed. The protective cover may be discarded after the pocket has been installed.
• POLYURETHANE ENCAPSULATION: Using ACE standard clear double zinc plated, corrosion resistant finished back boxes (BBX), 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 (BBXW).
