Router Table T-track is the perfect size for installing onto the face of your router table. These tracks have been pre cut to 11 1/2" so that they can be installed on your router table to hold fence assemblies. Why buy the larger 24" size models from other vendors and then have to cut them in half only to find out the holes are uneven. These tracks already have evenly spaced (3) holes predrilled and countersunk. What a time saver.
