J849X: Bronze Ground Rod Clamps, used with copper-bonded ground rods, provide a low resistance, secure copper-to-copper connection. These heavy-duty clamps develop a high-pressure contact between the rod and the grounding wire and can be easily disconnected when it is desired to measure resistance of the ground.

J771018: The grounding lug assembly consists of a 3/8" x 1-1/4" carriage bolt, complete with wire clamp, spring lockwasher and square nut.

J2727x: Galvanized steel bond clamps provide a sturdy and efficient provision to connect ground wire to threaded bolts. The clamps are designed to nest over the square nut of the bolt. The grounding connection is accomplished by inserting the ground wire between the nut and the bonding clamp and adding an additional nut to secure the clamp and ground connection. The clamps accommodate the most common range of ground wire diameters.
