Any recommendations on replacing pads on a pull up bar?

I don’t know if this is the right sub for this (if not kindly redirect me, thanks).

I have had this pull up bar for over five years and the pads are starting to wear. I could just use it without the pads but it does make it slightly more comfortable. I can’t imagine buying a new one. This one does exactly what it needs to do and it does it adequately. Any help is appreciated.
