These splices connect thicker wires than crimp-on butt splices—up to 1000 MCM. Tighten the set screw onto the wire instead of crushing the body, like you do with compression butt splices. That makes these splices reusable and easier to install.

PVC Cover—Completely cover the splice to protect wires from short circuits. The tip can be trimmed to fit your wire size. Cable ties cinch the cover onto the wire.

Underground Heat-Shrink Set Screw Butt Splices


Style A	Style B

Protect utility, irrigation, and other underground connections from groundwater, rocky soil, and mechanical stress. After tightening the set screws, slide the heavy-wall polyolefin tube onto the splice. Then, apply a heat gun to shrink the tube and completely seal out moisture and dirt.

Watertight Set Screw Butt Splices

End caps seal off the wire to keep your connection completely dry and conductive. Set screws cinch the wire without denting the body, so you can pop splices on and off for adjustments and reuse. For cable, attach each wire to its own set screw.
