If you have any new Burton binding using the newest ReFlex baseplates and need to mount them to that Burton Channel snowboard then these are the discs you need. You can tell what bindings you have in a couple of ways and the easiest is to look at the underneath of the binding and look for the word ReFlex. It is that simple. Another more subtle way is to look at the hole in the binding baseplate and see if it has small teeth on the edges of the hole that would match the teeth on the edges of these discs which are pretty obvious in the picture here.
