Insulated Set Screw Lugs
To prevent short-circuiting with nearby wire, a plastic cover insulates the barrel on these lugs. Tighten the set screw for a secure connection without crimping.
45° elbow lugs connect to wire at an angle, so they fit in tight spaces.
Lug covers go over the entire lug, so they prevent accidental contact with other connections.
