Manufacturer: Pearl Model Number: C-052 Mounting Screw Pitch: 39mm Quantity: 16 pieces These are Pearl separate lugs. They are in very good condition, with some minor scratches, but no peeling plating or rust. The C-052 corresponds to the current RL-10, and this is the older type that uses a spring to secure the lug nut, rather than a rubber stopper. This listing is for the lugs only; lug nuts and springs are not included. Please prepare appropriate ones. Also, the screws for attaching to the shell are not included.
