The Redi Lock Holder Assembly is the interface component that secures grinding tooling to the head of the PG400 floor grinder. It uses a quick-lock system to clamp segments or pads firmly against the drive plate, transmitting rotational force evenly across the grinding surface. When the holder assembly wears, cracks, or loses its locking tension, tooling can shift during operation — producing inconsistent surface finishes, accelerating tool wear, and creating vibration that stresses the machine's drive system. Replacing this assembly with part number this part restores proper tooling engagement and ensures the grinder performs as intended across concrete preparation and surface finishing applications.
