The NESCO ASB-4 is a Size 4 anti-short bushing built for mid-range cable installations — the kind you encounter on commercial branch circuits, appliance feeds, and multi-conductor runs. When you cut EMT or rigid conduit, the raw edge can abrade wire insulation and cause short circuits over time. The ASB-4 snaps securely over the cut end to create a smooth, insulated barrier that keeps conductors protected and installations code-compliant. Sized for #8/4, #6/2, #6/3, #4/2, #4/3, and #6/4 cable applications, this bushing handles a wide range of mid-gauge conductors that electricians pull daily. Sold in a bag of 16, so your crew stays stocked for multiple runs without reordering.
