Use Bridgeport’s 1003 Trade Size 3 (1/2") Anti-Short Bushings to protect conductor sheathing from sharp edges and rough ends within AC, MC and MCI-A cables. Place the bushing between the outer metal armor and the conductor at the point of connection to form a protective shield. Called "redheads," these bushings are made from sturdy red polyethylene plastic and are rated up to 90℃. Bushings are both UL and CSA listed. Trade size 3 bushings fit cable sizes 10/4, 8/2, 8/3 and 1/1.
