This is the Jim Dunlop Straplok system. It's not the recessed type, so it can be used with general guitars & basses. The color is black. I bought it but didn't use it, so I'm selling it unopened. The price has been reduced, so please be aware that dents in the outer box due to shipping methods are not covered. This set includes strap-side locks, lock pins, and mounting screws. - Brand: Dunlop - Model: Straplok Strap Retainer System - Color: Black ■ Strap Lock ■ Dual Design Wide Flange Type ■ Color: Black ■ The strap lock pin set is a combination of the strap lock system button and screws to attach to the instrument, and the strap lock system attachment to attach to the strap side.
