Set Screw Lugs


For 2 Wires	For 3 Wires	For 4 Wires

These lugs attach to even larger wire than compression lugs, such as the 1000 MCM building wire used in large factories. They're also easier to install and reusable because you cinch the wire with a set screw rather than crushing the barrel. They don't hold the wire as securely as compression lugs, however—use them when pulling and bending aren't a concern and you need to easily break your connection for maintenance or adjustments.

Compression Lugs

Straight

These lugs connect wire as large as 500 MCM in industrial feeder circuits, high-power service entrances, and other large systems. Squeeze the barrel tightly and evenly onto the wire with a compression tool for a permanent connection that stands up to heavy vibration, sudden shocks, and daily wear and tear. Compression lugs are a step up from set screw lugs when you need a physically strong connection, though set screw lugs attach to even larger wire.

Single Crimp—Provides a secure enough grip for most jobs.
