Hot Arm Conversion

Convert old hot arms to fit new composite/fiberglass cross arms

With Composite Cross Arms, Wider Clamp Needed

More and more composite (or fiberglass) cross arms are installed every day. These composite cross arms are wider in diameter than the wood cross arms that have been used historically.

See picture comparing two hot arm saddle clamp diameters. The top clamp is standard on old hot arms, and the bottom clamp with wider diameter opening is new and can be added to existing hot arms.

Hot arms need to have this wider diameter saddle clamp installed in order to fit these new composite cross arms.
