Step 57: Assemble Rock Wall
Part 3
It is important to note hole orientation for the following steps.
F: Loosely attach each Climbing Crater Rock with 1 (PB2) ¼ x 1-1/4" Pan Bolt (with lock washer, flat washer and
barrel nut) per rock. Maneuver each rock so that the second hole lines up with the pre-drilled hole in the board.
Insert Pan Bolt into the second hole as a pin holding Climbing Crater Rock in place and mark the location for the 3rd
hole.
G: Remove Pan Bolt from second hole and swing Climbing Crater Rock out of the way. Drill a 3rd hole in the
marked location using a 3/8" Drill bit.
H: Install remaining 2 (PB2) ¼ x 1-1/4" Pan Bolt (with lock washer, flat washer and barrel nut) in each rock and
tighten all bolts.
Note: Make sure all hardware is used and tightened to secure each rock properly.
