Saddle Rider No-Slip Rubber Threaded Endpin Ball

Works great! I still have mine from a year ago and I love it

Endpin Ball

I like the rubber endpin ball because it does not slip on the floor. I purchased two of your threaded model, hoping it would fit both of my basses. It was perfect for my Framus bass, but too small for my Alfred Stingl. So then I bought the unthreaded model, which was too big. The good news is that I can stuff the hole with carpet tape or some similar material and make it stick to the endpin.
