The Precision Router Table System features a t-square design that reportedly keeps the fence parallel to the miter slot. According to the company, the automatic squaring enables users to fully use the miter slot and makes it easy to make small adjustments on the fly. The fence is constructed of a rigid, fully enclosed aluminum extrusion, designed to support large workpieces and create a full-length vacuum chamber for superior dust collection. Other features include a rugged table top, insert plate, dual reducing rings, and flexible steel stand. (800) 447-8638, KregTool.com.
