Used to install ground rods, the heavy-wall tubular steel handle installs all but the last three feet of rods (of diameters up to 3/4"). Installation is completed with the 2 1/4" diameter medium carbon steel square hammerhead. For additional safety we recommend using the H-207 Ground Rod Cap. The H-691 is 43" long and is painted.
