Schaller Strap Locks BlackNever worry about your guitar strap slipping off again! One half screws into the body and the other half is secured onto the strap ends with a washer and a nut. The strap connector then snaps on to the body post and a spring loaded pin locks it all firmly in place. The body post is shaped similar to a standard strap button so you can use any standard strap on it if need be. Please inquire about stock availability unless otherwise stated.
