Grounding Rod Clamps
Connect bare-copper ground wire to grounding rods.
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.
UL 467 clamps meet a standard for direct burial.
