On my climber the rubber coating is coming off the chains. Makes it a lot harder to use. Does anyone know where i could get replacements?

Shrink tubing or covering with thin bike inner tube.Its one of the short comings of the motorcycle type climbing chains.As the covering wears off they start to clank when you carry them thru the woods.

Go to ebay and search for tree stands. There is almost always API shrinkwrap tubing for sale.

I get mine from a local electronics store. Try one of those in your area.
