The large dual sliding fence gives maximum support in large material cuts at any angle or combination of angles. Linear horizontal rails utilise bronze guides to provide maximum precision when cutting materials up to 345mm wide. New quick release bevel setting provides accurate and simple setting of bevel angles up to 48° left and right. Compact and lightweight design characteristics deliver a saw with enormous capacity which is easy to transport around the jobsite
