Carlon PVC non-metallic male adapters can be used with Sch. 40 and Sch. 80 RIGID non-metallic conduit (RNC). Designed for use above ground and underground as described in the NEC. Carlon fittings ensure raceway integrity. Unlike metallic systems, on-metallic fittings are lighter, can be installed in less time and are easily fabricated on the job. Fittings are nonconductive assuring a safe system. Resistant to sunlight and listed for exposed or outdoor usage, Carlon non-metallic PVC fittings are durable and will not rust or corrode.
