Metallics ASB2 Bushings 7/16 Anti Short 2 Cbl (Bag 35)

It is the small nylon insert, often called a red head, that goes into the cut end of armored cable before the connector is tightened. The bushing sits between the conductors and the sharp spiral edge of the armor so the metal cannot cut into the insulation. The ASB2 is the 7/16 inch size for 2-conductor cable.

The ASB2 is sized 7/16 inch for 2-conductor armored cable. Pick the bushing by the cable's conductor count and armor size, not by the connector: a 3-conductor or larger cable takes a different size bushing, and an oversized bushing will not seat inside the armor.

They are bagged 35 to a bag, and 35 pieces is the minimum order count. That is a practical quantity for an electrician wiring a floor of MC or AC runs, since every cable termination takes one bushing at each end.

The ASB2 bushings are flagged as both ARRA compliant and Buy American compliant, which is what a public agency or institutional procurement office normally needs documented on an electrical submittal.

Many MC connectors are listed without a separate bushing, but AC (armored) cable terminations are where the anti-short bushing is expected, and plenty of specs and inspectors call for one on both. Keeping a bag of the 7/16 inch ASB2 on the truck covers the 2-conductor runs where it is required, and it is cheap insurance against an armor edge nicking insulation inside the box.

Nylon. Inspectors generally want to see the bushing through the connector's inspection window or at the cable end, and the molded nylon body is what they are looking for on an AC cable termination. Nylon also keeps the bushing from cracking when the armor is pushed home.

The bag is listed at 0.45 lbs, with packaged dimensions of 3 x 3 x 3 inches. Light enough that MRO buyers usually add several bags to an existing order rather than ship them alone.
