The IncraLOCK Flip Fence and the extending IncraLOCK Flip Fence SE are both designed to give you outstanding fence performance and rigidity. Manufactured by Incra from aircraft grade aluminium extrusions, this fence profile is designed to coordinate perfectly with the Flip Shop Stop. The interlocking fingers on the Stop and Fence give you a perfect stop even when cutting sharply mitred workp ieces. And of course, INCRA's patented rack system is fully integrated in the fence to give you the incremental accuracy made famous by Incra tools.
