Conduit Clamps are engineered to accommodate proper expansion and contraction of PVC conduits and to prevent unwanted clamp opening. Other features incorporated into the design include multiple mounting options and the ability to be linked together – regardless of the size of the adjacent clamp. CCS15 3/4" NM COND. CLAMP AND SPACER SCEPTER PRODUCT LINE: Scepter Rigid PVC Fittings includes adapters, couplings, elbows, access fittings, boxes, cover plates, expansion fittings and conduit spacers - virtually any fitting required to complete the PVC conduit system. Easy installations, the ability to perform in demanding environments and labor savings are the reasons non-metallic conduit fittings are increasingly the fitting of choice. FEATURES: Lightweight yet offers high impact and tensile strength;Chemical resistant to a wide range of acids, alkalis or salt solutions;Corrosion resistant for lower maintenance cost and longer life;PVC is nonconductive eliminating dangerous second point of contact;Lightweight yet offers high impact and tensile strength;Chemical resistant to a wide range of acids, alkalis or salt solutions;Corrosion resistant for lower maintenance cost and longer life;PVC is nonconductive eliminating dangerous second point of contact
