Frustrated at the lack of foot options to prepare climbers for the precision of many outdoor climbs. Ayo from MBP shaped some great little duel texture feet!
Using general construction screws, drywall screws, or any non-structural screw can be dangerous when installing climbing holds.
GRK #9 screws have a structural rating (#8 GRK do not) and are the only screws we recommend for installing climbing holds. Safely installing holds is important with precious hands pulling on these plastic grips.
