The part that is supposed to wear, so your lasher does not. This stainless steel door wear plate fits GMP C, C2, and J lasher doors and takes the wing nut contact that would otherwise grind into the lasher door itself. Wear plates are designed to be sacrificial, and a grooved or worn-through plate has done its job. It is telling you it is time for a fresh one.
Swapping the plate before it wears through protects a machine worth far more than the plate, which makes this one of the highest-value service items on the lasher. The plate ships with its mounting rivets for a clean install. Like all NPT lasher parts, it matches original fit and function, supplied by the Pennsylvania shop that has been repairing GMP lashers for decades.
