Appleton SR-950-250 Strain Relief Bushing 1/2 in

Product Description

The APPLETON SR-950-250 is a strain relief bushing designed to secure and protect electrical cables at conduit or enclosure entry points. This fitting accepts cables with an outside diameter ranging from 0.156 to 0.250 inches and installs into a 1/2-inch trade-size knockout or conduit opening. The bushing grips the cable jacket to relieve mechanical stress at the point of entry, preventing insulation damage and maintaining a secure connection. At 0.290 pounds, it is a lightweight, compact component suited for panel, junction box, and enclosure wiring work performed by licensed electricians.

This strain relief bushing is used in residential and commercial electrical installations where cables pass through enclosure walls, junction boxes, or conduit fittings. It is appropriate for applications requiring mechanical cable protection at entry points, including control panels, electrical enclosures, and low-voltage wiring assemblies. The 1/2-inch trade size fits standard knockout openings common across a wide range of electrical enclosures and boxes.
