Rock climbing hangers is made of heat-treated precision high-strength carbon steel or stainless steel. It is designed to fold into a symmetrical right angle to facilitate the climber's foot. The circular general aperture of 8 mm(3/8") and 12mm(1/2") is used to pass through the expansion bolt. The elliptical inner hole is used to hang the lock catch and iron ring. The edge is polished to avoid cutting the rope.
It is widely used in indoor and outdoor rock climbing and exploration to provide safety for climbers.When in use, drill to the required depth, hammer the anchor into the hole through the round hole, and place the required hanger, washer and nut. Tighten the tapered end of the nut bolt into the metal ring to expand it to complete the installation. For the purpose of safety protection, it is recommended to drill deep holes, so that when the device is corroded in the future, it can be directly hammered into the rock, because the expansion bolt is a disposable product. The rock cannot be re bolted and re tightened so that the installation is not safe.
