Our Chain Derailer is easily mounted at the base of the saw bar and kicks a broken or derailled chain off of the sprocket so that it is no longer being driven while loose from the channel of the saw bar.
The Derailer
The ABI Chain Derailer is a durable bolt on attachment to the existing saw mount on your processing head.
When a chain breaks or is knocked out of the channel of the bar, the chain derailer shifts the chain off of the sprocket. Doing this makes sure that while the loose chain is still spinning it will not sustain or increase its momentum.
