Yes, they will fit with any new channel board ...or normal burton 3-hole pattern.

The new Channel boards will come with a two hole disk that fits seamlessly in the tray of that (or any) Burton disk binding.

However, if you do in fact have a channel board. You should definitely step up and kit it out with a pair of EST bindings. They will give you unparalleled board flex and feel!

Stoke you out!
