Connect bare-copper ground wire to grounding rods.

Dual nut clamps give you more flexibility than single nut clamps.

U-bolt clamps are the most adjustable and work with rods ranging in size from 3/8" to 1".

Clamps with a floating pressure bar distribute pressure evenly over a large area, which creates more contact area for grounding.

Two-piece design clamps are easier to install onto bends and continuous loops than other single- and dual-nut clamps.

For clamps with lay-in wire, there’s no need to thread wire through them. Simply lay the wire into the clamp’s opening and fasten.

UL 467 clamps meet a standard for direct burial.
