Abb Installation Products B620HG-UPC Ceiling Box Adj Bar Hanger

Product Description

The ABB INSTALLATION PRODUCTS B620HG-UPC is a ceiling outlet box with an integrated adjustable bar hanger designed for mounting lighting fixtures and ceiling fans in residential and light commercial applications. The box measures 4 inches in diameter and 2.25 inches in depth, offering 20 cubic inches of wire capacity. The bar hanger adjusts from 11.5 inches to 18.5 inches to span standard and non-standard joist spacing. Six integral clamps secure incoming cables without separate connectors, and a grounding lug screw is attached at the factory. The non-conductive, non-corrosive construction is suited for environments where moisture or chemical exposure may be a concern.

This ceiling box is intended for new construction and retrofit installations where a structural box must be mounted between joists without direct fastening to framing. The adjustable bar slides and locks to fit joist spans in the 11.5-inch to 18.5-inch range. The 3/0-4/0 combination knockout configuration accommodates standard conduit and cable entries. Fixture spacing is designed for 2.75-inch and 3.5-inch mounting patterns, making it compatible with a wide range of ceiling fixtures and fan canopies commonly installed in residential settings.
