L.H. DOTTIE SC125U Conduit Clamp 1-1/4 in Steel Electro

Purpose and fit

This L.H. DOTTIE SC125U clamp secures 1-1/4 inch EMT conduit to strut channels in electrical installations. It suits electricians and contractors running rigid metal raceways in commercial or industrial settings. The steel body with electro plating resists corrosion in dry indoor environments. Buyers needing PVC or flexible conduit support should choose a different clamp style.

Pre-install checks

Verify the conduit is standard 1-1/4 inch EMT before ordering, as the clamp is sized for that specific outside diameter. Confirm the strut channel profile matches the clamp mounting design so the hardware seats correctly. Check local code requirements for support spacing and grounding continuity with electro-plated steel. The product carries a California Proposition 65 warning for chemicals linked to cancer and reproductive harm.

Build and daily use

The steel construction with electro coating provides adequate strength for typical EMT loads while offering a smooth surface that reduces wire pull friction. The open-back design allows the clamp to slide onto strut without disassembling adjacent runs, speeding up adjustments on live job sites. Electro plating is not suited for wet or highly corrosive locations; consider stainless or hot-dip galvanised alternatives for those conditions.
