Sta-Kon C26U 90 DEG RNG TRM 10-12 AWG NO10 BOLT

The C26U is sized for 12-10 AWG conductors. If you are terminating 14-16 AWG or anything larger than 10 AWG, this barrel will not grip properly and you need a different size terminal.

The ring tongue is made for a No. 10 bolt or stud, so it drops over a #10 screw on a breaker lug, terminal block, or ground stud without reaming.

It is a non-insulated terminal, bare copper with no sleeve. Where the connection needs to be covered for code or for clearance inside a crowded enclosure, plan on heat shrink or a vinyl insulating cap over the barrel after crimping.

The 90 degree bend turns the tongue perpendicular to the wire barrel, so the conductor runs parallel to the panel or device face while the ring still lands flat on the stud. That is what you want in a shallow enclosure, on a stacked terminal block, or where a straight terminal would force a sharp bend in the wire right at the crimp. If your stud faces the same direction the wire runs, use a straight ring terminal instead.

No. This is a copper terminal and should be used on copper conductors only. Aluminum wire needs a terminal rated AL or AL/CU with the appropriate inhibitor compound.

Yes, country of origin is the United States, which matters if you are filling a government or institutional order with domestic sourcing requirements.

It is a crimp terminal, not a screw-down lug, so it needs a crimper matched to the 12-10 AWG barrel. A non-insulated crimp die (not an insulated-terminal nest) is what gives the correct compression on bare copper barrels like this one.
