Orbit Industries HB-1-MKO-EXT Handy Box Extension Steel

Product Description

The ORBIT INDUSTRIES HB-1-MKO-EXT is a welded steel handy box extension designed for electrical wiring installations in residential and commercial construction. Measuring 2 inches x 4 inches x 1-7/8 inches and formed from 16-gauge sheet steel with a galvanized finish, this extension box provides additional depth and knockout options where standard single-gang boxes fall short. The box ships with four 1/2-inch knockouts and four MKO (multi-knockout) openings on the sides, giving installers flexible conduit and cable entry points without extra field modifications. Licensed electricians install this component during rough-in or device-mounting stages of an electrical project.

This handy box extension is suited for residential and commercial wiring applications where additional box volume or depth is required at a wall or surface-mounted device location. The galvanized steel construction handles the demands of standard indoor dry-location installations. The welded construction provides a rigid enclosure that holds its shape during conduit termination and device installation. It is commonly used when extending an existing handy box to accommodate deeper wiring connections or additional conductors.
