Crimp. The SBCL3 is a compression lug with a long barrel, so it gets installed with a hydraulic or battery crimp tool and the correct die for the conductor, not a set screw. Long barrel means two crimps on the barrel for the pull-out strength a grounding connection needs. Contractors who want a tool-free termination should be looking at a mechanical lug instead.

Two-hole pad. That matters on a ground bar or busbar because a two-hole termination resists rotation under fault current and vibration, and many grounding details on commercial and telecom drawings call for two-hole lugs specifically. If your bar is drilled for a single stud, this is the wrong pad configuration.

The SBCL3 lugs are tinned copper. The tin plating over the copper body slows oxidation at the contact face and reduces galvanic issues where the lug lands on a plated ground bar or a dissimilar metal enclosure. For outdoor pads, generator grounds, and damp electrical rooms, tinned is the normal specification.

The SBCL3 is catalogued as a grounding wire connector, and that is the application Eaton B-Line states for it. If you are terminating phase conductors in a switchboard or panel, specify a lug rated and listed for that use rather than assuming a grounding lug covers it.

Order by manufacturer part number SBCL3, from Eaton's B-Line series. That number covers the ten-piece pack of long barrel compression lugs with a two-hole tinned copper pad.

Ten pieces per package. That is a contractor pack rather than a single, which suits terminating both ends of several grounding runs or stocking a truck for service work. Total package weight is listed at 20 lb.
