This versatile range of Wallis ‘U’ bolt clamps can be used to connect flat tapes and stranded cables to earth rods, reinforcing bars (rebar), handrails etc.

These ‘U’ bolts are used to connect stranded cables in a vertical and horizontal position on the rod and are manufactured from high copper alloy with an M10 threaded copper ‘U’ bolt. The only exception to this is the ERU470 which has an M8 threaded copper ‘U’ bolt.
