API TREESTAND REPLACEMENT CHAIN COVERS for ALL API'S INCLUDING THE GRAND SLAM, SUPER MAGNUM and 3500 MODELS.

API replacement chain covers/shrink tubing for ALL API climbing treestands. You will get 2 lengths of very high quality shrink tubing 69" long, enough to cover both chains. Punch the holes with a Philips screwdriver or similar tool where you want them after the tubing has been been shrunk onto the chains. This black shrink tubing is flexible, durable and of excellent quality. All you need to do is to pull the chain into the shrink tubing with wire or string, apply heat, and you’re done. The best way to heat it is with a heat gun. You can use a torch but you take the chance of burning the tubing if you are not careful.  

In my opinion, all chains should be checked after a lot of use by cutting the heat shrink off and checking to make sure the chains do not have any cracks. I checked two climbers recently and had small cracks in several links. The stands are only a couple of years old and the chains were what came with the stand when purchased new. 

Thanks for looking.
