An adjustable fence structure in combination with the work supporting table of a power tool. The fence structure is a parallogram frame structure including elongate, parallel mounting and fence rails and a pair of elongate, parallel links spaced longitudinally of, extending between and pivotally connected with said rails. The fence structure includes a locking device to releasably lock the rails and links against pivotal movement with said rails in set lateral spaced parallel relationship and which includes an elongate lock bar with one end pivoted to the fence rail and its other end portion pivotally and slidably connected with the mounting rail with the longitudinal axis of the bar angularly related to the longitudinal axes of the rails and links. The locking device includes a screw part to releasably clamp the bar in set position on the mounting rail. The fence rail slidably carries an elongate glide with a flat, vertical, work engaging flange and a portion formed to establish sliding supporting engagement with the fence rail whereby the glide is parallel with and is substantially free to shift longitudinally of the fence rail and relative to the table.
