The NESCO ASB-1 is a Size 1 anti-short bushing designed to protect cable insulation at cut conduit ends — a critical detail that prevents abrasion, insulation damage, and short circuits before they happen. When you cut EMT, IMC, or rigid conduit, the raw edge can slice through wire insulation over time; the ASB-1 snaps securely over the cut end to create a smooth, insulated barrier that keeps conductors safe and installations code-compliant. Sized for #14/4, #12/3, #6/1, and #4/1 cable applications, this bushing is a daily essential for commercial rough-ins, residential wiring, and industrial panel terminations. Sold in a bag of 35 so your crew stays stocked for multiple runs without reordering.
