## Abstract

A router guide jig includes a frame assembly that includes a first leg, a second leg, and a support member. The support member has an opening extending through the support member positioned at least in part offset from the first leg. The receiving opening defines a first axis. The router guide jig includes at least one backset member carried by the first leg having a first abutment surface facing away from the first leg. The at least one backset member is positionable in at least a first position and in a second position relative to the first leg. In the first position, the first abutment surface is spaced a first distance from the first leg. In a second position, the first abutment surface is spaced a second distance from the first leg. The router guide jig includes at least one clamp member carried by the second leg having a second abutment surface facing away from the second leg. The at least one clamp member is adjustable relative to the second leg to adjust a clamping force provided by the at least one clamp member.
