The Rockler Router Table Half Lap Jig is the only jig on the market that makes it possible to easily cut both regular half lap joints and mitered half lap joints at the router table. Half lap joints boast maximum glue area, resulting in an incredibly strong joint. Use the mitered version for a pleasing appearance on things like picture frames, and the square version for more structural frames and ease of assembly.
