Set Screw Lugs
The straight tongue improves conductivity by increasing the surface contact between the lug and your equipment. Tighten the set screw onto your wire for a secure connection without crimping. Mount lugs to a screw.
Copper lugs can be used in large power distribution systems, motors, and generators.
Aluminum lugs are more lightweight and can be used in electrical distribution systems.

Harsh-Environment Screw-Down Butt Splices
Splice for Four Wires
Splice for Eight Wires
Join wires in the dirtiest, wet, and harsh environments. These splices meet one of the toughest IP ratings—IP68. Because they’re IP68, they’re dust- and watertight and can even be submerged in 5 meters of water for 30 minutes. Use these splices to repair or extend your electrical circuits without needing special tools. Insert your wires into these splices, tighten the screws with a slotted screwdriver, and then twist on the gasketed end caps for a reliable, tight seal.
