Complete overhaul of the Liteflip flip-up mechanism
The Optrel Liteflip helmet is designed for maximum versatility, and its key advantage is the flip-up flap mechanism that lets you switch instantly from welding to grinding or inspection. Parts such as springs and pins go through thousands of operating cycles and gradually wear. This repair set contains all the key moving components: a new flap, return springs, main springs and retaining pins. Replacing these parts precisely restores the original smoothness, force and reliability of the flip-up mechanism. With this set your helmet regains full operation and gives you the same comfort and safety as on the day you bought it.
