What Is a Spring Lock R Pin?
A spring lock R pin is a quick-release locking clip used in scaffolding to secure connections safely during erection and dismantling work. It locks bolts, hinge pins, and couplers firmly in place while allowing easy removal without tools.
Because of its spring tension design, the R pin provides secure retention under vibration and movement, making it ideal for construction and industrial applications.
