Black nylon anchor strap for double bass and cello, Y-shaped stopper and metal ring, with non-slip rubber on the back. Used once or twice after purchase and then stored. There is a slight scratch only on the part where the endpin is inserted, but no other noticeable damage. The length is also adjustable. You can hook the ring on the chair leg and insert the endpin into the Y-shaped part, so it won't slip. It stabilizes your seated playing and allows for good posture. For all double bass players out there who are seeking an endpin anchor strap, I’ve barely used this after I bought it in Italy many years ago, and I’ve held onto it since. Since I don’t have a chance to use it, it needs a new home. To use it, the leg of the chair you sit on will go into the ring, and the pin goes into the arrow shaped bit. Great for those with back pain or want to prevent back pain since you can sit comfortably. This is one of the two I have so please check out the other one as well. Thx, and happy playing! - Color: Black - Material: Nylon - Type: Endpin holder strap for double bass - Design: Adjustable with Y-shaped plastic clinch; plastic ring goes around the leg of your chair and the endpin goes on the y-shaped bit. - Ring: Durable plastic ring. *1/2
