Connect ground wire for transformers, control panels, and other electrical distribution components without cutting and splicing. Unlike other lugs, these attach in the middle of a run of wire, not the end—just lay the stripped wire into the lug and tighten the set screw.

Crimp wire into dozens or even hundreds of terminals in a fraction of the normal time. These terminals come attached to a reel that feeds into an automated crimper (not included) for large-volume electrical installations. They also have an open barrel, so you can lay your wire into place instead of threading and poking into a closed barrel.

Ring terminals encircle the whole screw shank, so they stay put better than spade and hook terminals when vibrated or pulled. They take a bit longer to install, however, because you have to completely remove the screw.
