Abb 653 Handy Box Extension Ring Outlet Box

Product Description

The ABB 653 is a handy box extension ring used to increase the depth or volume of a standard single-gang handy outlet box. This fitting mounts directly onto an existing handy box, creating additional wiring space for conductors, devices, and wire nuts. It is a common component in commercial and residential electrical rough-in work, installed by licensed electricians during new construction or renovation. The extension ring allows compliance with NEC box fill calculations when device count or conductor volume would otherwise exceed the base box capacity.

The ABB 653 extension ring is suited for use with standard single-gang handy boxes in light commercial and residential electrical installations. It is typically used in surface-mounted wiring applications where conduit-fed boxes are installed on walls or exposed structural surfaces. This part is installed during rough-in or when an existing box requires a volume upgrade to meet code.
