Volume #1 has steep wall angles ( 15, 20, and 25 degrees), which adds dimensional aspects on super-steep terrain and roofs. There is room for holds that have a 4" footprint, which means it easily fits most medium holds and large holds and even some extra large ones.
Base Dimensions : 10-1/8" x 10-1/8" x 10-1/8"
Stand out from the wall: 7-3/8"
T-nuts installed: 3 round base t-nuts.
Attachment method: One 3/8-16 Allan head bolt (7-1/2" long) and three structural spinner screws. You should attach the volume using all four attachment points.
Please do not drill spinner screw holes or any other holes into Polyurethane Volumes. You can weaken the structural integrity of the product. This practice also voids our warranty.
