Plug for electrical junction boxes and connectors

Ground clamp

Saddle type connector

A closure or bushing member for openings in electrical boxes, conduit ends and the like is formed as an integral unit of a thermoplastic synthetic organic polymeric resin and includes a disc or annular shaped head and a coaxial hollow cylindrical shank of lesser diameter. Extending from opposite sides of the distal end of the shank are a pair of opposite radially projecting arms, which terminate in wing members of greater width than the radial arms and which have conically surfaced outer faces flaring rearwardly outwardly. A peripheral recess is formed in the rear outer face of each wing to provide a rearwardly facing shoulder for resiliently engaging the inside border of the opening to which the closure member is applied to retain the closure member therein.

One piece knock-out plug

An electrical conduit grounding device includes a clamp formed of a pair of similarly shaped screw connected clamp sections each formed of a web including a crowned medial section terminating in coplanar wings and provided with longitudinal flanges. One of the clamp sections is provided with a cable clamp at the crown apex and which is stamped and shaped from the web, leaving corresponding openings therein, and includes first and second laterally spaced vertical arms atop the crowned section, a longer arm terminating in a horizontal leg projecting toward and above the top of the other arm. The leg has a tapped vertical bore engaged by a cable clamping screw.
