The NESCO TRTSCP-25 is a 2-1/2" raintight steel compression coupling engineered for professional electricians and contractors who demand reliable moisture protection on larger EMT conduit runs. Built to handle the rigours of Canadian job sites — from exposed outdoor installations to damp industrial environments — this coupling delivers a secure, watertight connection without the need for additional sealing. Its steel construction resists corrosion and mechanical stress, making it a dependable choice for commercial, industrial, and residential rough-in work where code compliance and long-term performance are non-negotiable.
