Installation Instructions

You will need twelve 1-1/2" long 3/8" lag bolts and twelve 1-1/2" 1/4" lag bolts for each set of rocks. Determine difficulty and height wanted. For one set of rocks, use 1" plywood, for taller set, use thicker plywood. Plan configuration wanted for rocks. Place rock on board and mark with pencil where holes need to be drilled. Drill a small pilot hole for lag bolts. Then using a 9/16" socket, screw 3/8" lag bolt through large hole in rock grip. Do not tighten until second bolt is installed. Using a 3/8" socket, screw in the 1/4" lag bolt. Tighten both screws. Continue procedure until all twenty-four bolts are screwed in completely. Make sure no sharp point protrudes beyond back of plywood.
