25 large screw on climbing holds. Here at Rocky Mountain Climbing Gear we make our climbing holds out of recycled materials. Our climbing holds are so realistic that customers do not believe me when I tell them that the holds are not real rocks. We have a lifetime warranty on all our holds. Rocky Mountain Climbing Holds will stand up to any environment and are the holds used in Military bases all over. the U.S. Thanks to our customers we are able to keep usable materials out of land fills. These climbing holds use a 2 1/2" wood screw. Screws are not included.
