As great as they work on a cast iron table, the Grip-Tite Magnetic Feather Boards become much more versatile when they're used on the vertical face of the fence. Few fences accept the system's magnets, so the solutions are these steel faceplates.
These 14ga steel plates are 4" high and come in lengths of 36" or 42" for the table saw, or in a pair of 12" lengths for infeed/outfeed use on the router table. Check out the Sub Fence Hole Clamps for an easy way of attaching/detaching the Steel Fence Plates on fences that don't have T-slots.
