Overview
The Bridgeport 1103-DC conduit nipple is a 3/4″ chase nipple manufactured from die cast zinc with a ball burnished (mirror smooth) finish. This compact nipple is engineered for use with rigid and IMC (Intermediate Metal Conduit) applications, serving as a short raceway connector between electrical enclosures, boxes, and lighting fixtures.
