WoodRiver® Fence Adapter T-Track is the easiest way to make fence faces for your miter gauge, router table or drill press. L-shaped profile contains two 1/4" T-Track profiles that mount to the back of nominal 3/4"/18mm plywood or MDF frame material. Front opening T-Track rests on top edge of your fence face material to hold 1/4" bolt heads and nuts to attach stops, featherboards and other accessories. Shallow top opening T-Track can be used to hold 1/4" T-Bolts for stops and guides. Durable extruded aluminum construction with V-groove on the rear of the track to help align holes that you drill for mounting.
