Clamp Connector · 1-1/4 in trade size zinc die cast 2-screw strap type · Bridgeport 664-DC2

SKU: NES-664-DC2

1-1/4 in zinc die cast 2-screw strap-type clamp connector for terminating a single round non-metallic service entrance cable to a box or enclosure. Fits a 1-1/4 in knockout and is commonly used where a secure mechanical cable connection is required.

What this product is for

This 1-1/4 in trade size clamp connector is used to connect a single round non-metallic service entrance cable to a box or enclosure. It provides a mechanical cable hold with a 2-screw strap design for electrical rough-in and service work.

Use for

Use for terminating round non-metallic cable into a 1-1/4 in knockout in residential, commercial, and light industrial installations where a zinc die cast strap-type connector is specified.

Avoid for

Avoid using this connector for cable types or outside diameters outside the listed range, or where a raintight, insulated, or bonding-specific fitting is required. Always match the fitting to the cable type, enclosure, and local electrical code.

Best for

Best for electricians needing a straightforward 2-screw connector for single round service entrance cable with a 1-1/4 in trade size opening. The zinc die cast body suits general indoor electrical installations.

Installed in

Typically installed in panels, meter bases, junction boxes, and enclosures with a 1-1/4 in knockout. Commonly used where cable outside diameter is approximately 1.09 to 1.30 in (27.7 to 33.0 mm).

Why this product exists

This fitting secures round service entrance cable at the enclosure entry point to help reduce cable movement and provide a clean, code-aligned termination method. Proper fit depends on cable construction, jacket thickness, and installation conditions.

Compared with similar products

Compared with compression or raintight connectors, this strap-type connector is intended for standard dry-location cable entry applications. Compared with single-screw styles, the 2-screw strap design is commonly chosen for a firmer clamp on larger round cable.
