Grounding Rod Clamps
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".
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.

Wire Rope Clamps with Thimbles—Not for Lifting
A clamp and thimble in one convenient fitting simplifies installation while providing support and fray protection to the wire rope loop. Use a torque wrench to tighten the clamp.
Warning: Test all assemblies for required strength before use. Do not use with coated rope unless the coating is removed.
