Durability and design

Durability begins with the layup of high-quality plastic and copper components. The parts are engineered to resist everyday wear—helping reduce the chance of wires coming loose and guarding against impact, abrasion, moisture, and dust. An ergonomically recessed body with radial ridges makes insertion and removal smoother, while transparent wiring chambers provide a quick, visual check of terminations without disassembly.
