The Rout-r-Fence Ii looks as beautiful as its functions and features a cam locking fastening system that allows you to quickly lock and unlock your fence when needed. This high-quality fence is cut and bent out of 12-gauge steel with white Mdf sub-fences. The top track is machined out of a custom aluminum extrusion that accepts most 1/4"" T-track router accessories. The sub-fence faces can be adjusted tool free with convenient locking knobs on the backside of the fence. The dust port fitting is designed with an inside diameter that accepts a 2-1/4""-diameter vacuum hose fitting and an outside diameter that accepts a 2-1/2"" vacuum hose fitting. The fence glides smoothly on the tabletop and is quick to take off and put back on without having to fidget around with lining up to side rails. Fits tables 32"" long x 3/4"" to 1-1/8"" thick.
