Strap-Type Connector · 2 in KO · Two-Screw for Round Non-Metallic Cable · Bridgeport Fittings 666-DC2
What this product is for
This 2 in strap-type connector is used to connect a single round non-metallic or service entrance cable to an electrical box or enclosure. It is a trade-grade fitting for larger round cable entries where a secure clamp and listed connector are required.
Use for
Use for terminating round non-metallic cable with an outside diameter of 1.75 to 1.95 in (approximately 44 to 50 mm) into a 2 in knockout. Common applications include service entrance cable terminations and other box or enclosure entries using large round cable.
Avoid for
Avoid using this connector for armoured cable, BX/AC cable, or cable sizes outside the listed diameter range. Do not use it where a raintight connector or a different cable-specific fitting is required by the installation conditions or local electrical code.
Best for
Best for electricians and contractors who need a two-screw strap connector for a 2 in knockout and larger round cable. The two-screw design helps provide even clamping pressure and a secure mechanical hold at the enclosure entry.
Installed in
Typically installed in panels, meter bases, junction boxes, pull boxes, and other enclosures with a 2 in trade-size opening. Suitable for indoor applications and other locations where the fitting type matches the cable and enclosure requirements.
Why this product exists
This connector exists to secure and protect a large round cable as it enters an enclosure while matching a standard 2 in knockout. Compared with improvised entries, a listed connector helps provide a cleaner, code-aligned cable termination and better strain control at the box wall.
Compared with similar products
Compared with squeeze connectors or smaller NM fittings, this model is built for larger round cable and uses a strap-style two-screw clamp. Compared with armoured cable connectors, it is intended for non-metallic or round service entrance cable rather than AC/BX cable. As typical guidance, matching the connector to both knockout size and actual cable outside diameter is the key buying decision. Actual fit depends on cable construction, jacket thickness, and local electrical code.
