I rubbed and used it while rubber was torn half.
After changing to a spare it is still comfortable.
I could not find it at home center, so it was saved.
Since it was being used outdoors, what was attached was rusty.
It is easy to install, but it was a pain to remove it.
The previous one did not last long since it was cut from the metal part and rubber part. By bending the part of the metal that holds the rubber outward, stress no longer exists, and the properties of rubber are not lost but supple movement. I think that it is a good improvement.
