Climbing Holds, Set of 10 Bouldering Holds We offer a discount of up to 10% for bulk purchases. Please feel free to consult us. This is a Sam Catch Hold / Kachi Hold. Material: Plastic (PLA-CF) Existing holds can also be used on steep inclines by attaching a thumb catch, and it can also be used as a finger catch on its own. Subjectively, I think it can hold up to about 95 degrees on bad holds and about 110 degrees on good holds. Precautions for Use Overtightening the screws can cause damage, but the material is strong, so I don't think it will break with normal use. Please use at your own risk.
