Coupling pins we offer are used to connect the scaffolding frames in a vertical way. They can get fit inside the frame and can be utilized with the span pins, clips, toggle pins, and others so as to hold them in place. These are usual nails and wire posts that can be bent into a ring form at one end. The Coupling pins are made to disassemble quickly. Coupling pins are sometimes used as fail-safes on connected rotating parts. The pins are accessible with a fail-safe feature and can do away with the expensive damage. They can resist the breakage during normal operation and damage.
