Konkore Fittings' Steel Bushing
Konkore Fittings’ steel bushing for rigid conduit, IMC and EMT is essentially a locknut and bushing in one body. The small diameter of the locknut, with the internal threads, is “stretched” to receive the insulating sleeve. It eliminates the use of the locknut and solves the problem of not enough thread left to engage the bushing after locknut installation. The main body is made from steel, and an insulating sleeve is polyetherimide.
