Blackburn 7019 COMP STIRRUP BAIL TP CU 2SOLID

The Blackburn 7019 is a compression stirrup bail, a copper connector crimped onto conductor to form a wire or cable compression splice. You install it with a compression tool rather than a wrench, so the joint is permanent once crimped. It's a grounding and bonding connector, not a mechanical set-screw lug, and it can't be loosened and reused.

A compression tool is required. The 7019 is a compression-type connector, so the copper body is deformed onto the conductor with a die and press. There's no set screw or bolt to torque. Plan on having the correct die and press on the truck before the crew is at the pole or panel, because there is no mechanical alternative for making this connection up.

Solid. The 7019 is built for 2 solid copper, so it's the right pick when the run is solid conductor. If what you're terminating is stranded, this is not the part to order, you need the connector and die sized for stranded conductor of that size instead.

Copper. The 7019 is a copper compression stirrup bail, which is what you want on a copper conductor run. Copper-to-copper avoids the dissimilar metal issue you'd have to manage with an aluminum or bimetallic connector, and it keeps a bonding path consistent with copper grounding electrode conductors elsewhere on the job.

Blackburn 7019. That's the number to quote or cross when a distributor or a spec asks for the exact item, and it identifies the copper compression stirrup bail configured for 2 solid conductor. Country of origin on it is Mexico, which is the detail that comes up on government and institutional orders with sourcing requirements.

No. Once the 7019 is crimped, the copper body is permanently deformed onto the conductor and the connection cannot be backed off and remade. If you expect to disconnect for testing or future re-termination, use a bolted or set-screw mechanical connector at that point instead and save the compression bail for the permanent splice.
