This is may be a bit unfair, but this piece didn't work with either of my upright basses, so make sure you can use it before you buy it.
I have an older upright from the 30's and it has a small bulge at the tip of the endpin. This bulge made it impossible to put the rubber piece properly in place. instead, it bent and broke. The other bass is a cheap chinese made plywood bass, and after on gig outdoors, the rubber piece was stuck in the ground and remained there when I moved the bass... so no, this was not for me.
I bought this floor protector for my bass, hoping that it would be somewhat sturdy and functional even though the low price. Thing is, it didn't. And for the price, I didn't expect much except that it would at least be able to balance my bass, but that was not possible. It kept bending under the weight under my bass and was impossible to use as it was intended. I understand that for the price you maybe shouldn't expect as much but I highly recommend that you buy something else.
