In the public domain like at playgrounds, it is often a requirement that climbing holds have two or more attachment points, to ensure a hold cannot rotate. Uncarved Block has produced holds specifically for this application.
Holds that Use Bolts: The holds have two bolt holes, and will accomodate the wider head of tamper-resistant torx head bolts. Every hold in all sets have the same bolt spacing, allowing the pre-drilling of anchors. Length of bolt required will depend on the requirements of the installation.
Holds that Use Screws: The holds have 3 pre-drilled screw holes per hold. It is recommended that a minimum of 8-10 gauge x 50mm screws are used. The screw heads will be countersunk when installed, the opening for the screw head is 8.5mm in diameter and the diameter of the hole is 5.5mm.
