Clamp Connector · 1-1/2 in trade size · zinc die cast 2-screw strap type · Bridgeport Fittings 665-DC2
1-1/2 in zinc die cast 2-screw strap-type clamp connector for terminating a single round service entrance cable to a box or enclosure. Fits a 1-1/2 in knockout and is commonly used where a secure mechanical cable hold is required in residential, commercial, and light industrial work.
What this product is for
This 1-1/2 in trade size strap-type clamp connector is used to connect a single round service entrance cable to a box or enclosure. It provides a mechanical cable clamp at the entry point and is intended for electricians and contractors working on feeder and service cable terminations.
Use for
Use for single round service entrance cable installations, panel and enclosure entries, and other box terminations requiring a 1-1/2 in knockout. Typical cable opening range is 1.187 to 1.490 in (approximately 30.1 to 37.8 mm).
Avoid for
Avoid using this connector for cable types or diameters outside the listed range, or where an insulated throat, liquidtight seal, or conduit-specific fitting is required. Confirm cable type, knockout size, and local code requirements before installation.
Best for
Best for service entrance and large round cable terminations where a zinc die cast body and 2-screw strap provide a firm hold. Suitable for residential, commercial, and light industrial electrical work.
Installed in
Installed in boxes, cabinets, meter bases, and enclosures with a 1-1/2 in trade size knockout. Commonly used in service and feeder cable entries.
Why this product exists
This fitting is designed to secure round cable as it enters an enclosure, helping reduce cable movement at the knockout and providing a code-recognized termination method when used in the correct application.
Compared with similar products
Compared with snap-in or plastic connectors, this strap-type zinc die cast connector is intended for larger round cable and uses two screws for clamping force. Compared with insulated or liquidtight fittings, this model is a basic mechanical connector for dry-location cable entry where those added features are not required.
