Two-Screw Strap Connector · 1-1/4 in KO · For Round Non-Metallic Cable · Bridgeport Fittings 664-DC2
What this product is for
This 1-1/4 in two-screw strap connector is used to secure a single round non-metallic or service entrance cable to a metal box, cabinet, or enclosure through a 1-1/4 in knockout. It provides mechanical retention at the cable entry point for indoor wiring work.
Use for
Use for terminating round cable into panels, junction boxes, pull boxes, and other metal enclosures where a strap-type connector is required. Commonly used for service entrance cable and other round non-metallic cable within the listed cable opening range of approximately 1.09 to 1.30 in (27.7 to 33 mm).
Avoid for
Avoid using this connector for wet-location exposure unless the complete installation is inside a suitable weatherproof enclosure. Do not use it where a different connector style, cable type, or knockout size is required.
Best for
Best for electricians and contractors who need a straightforward two-screw connector for larger round cable entries into metal enclosures. The strap design helps provide a firm hold while keeping installation familiar for service and rough-in work.
Installed in
Typically installed in indoor residential, commercial, and light industrial electrical systems, including service equipment, distribution points, and equipment enclosures with a 1-1/4 in trade-size knockout.
Why this product exists
This fitting is made for cable-to-enclosure transitions where the cable needs to be secured at the knockout and protected at the entry point. Compared with improvised cable entry methods, a listed connector helps support code-compliant workmanship and a cleaner enclosure finish.
Compared with similar products
Compared with single-screw styles, a two-screw strap connector is commonly chosen when installers want more even clamping on round cable. Compared with smaller connectors, this model is sized for 1-1/4 in trade applications and larger cable diameters. Always match connector size and cable range to the actual cable being installed.
