Finger joints, also called box joints, add visually striking symmetrical design to corner assemblies. Unlike dovetails, finger joints do not interlock mechanically but their enormous glue surface area makes them as strong as dovetails throughout the life of todays modern adhesives.

Leighs versatile 16" F1600 Finger Joint Template is the most comprehensive and accurate jig of its kind. The F1600 produces eight sizes of precisely fitted box joints: 1/16", 1/8", 3/16, 1/4", 3/8", 3/4", 1/2" and 1", and can also produce three sizes of square half-blind joints.

Joint fit is easily and precisely controlled using Leigh's patented Variable Guidebush System (VGS), a unique adjustable 3-piece template guidebush. Rotating the barrel of the VGS, up or down, increases or decreases its active diameter. A 1/8 turn of the barrel adjusts joint fit by a mere 1/1000 of an inch! The VGS comes standard with every F1600 Template, as do three tapered guides, one for each comb size. The VGS mounts directly to many router bases. Some routers may require a Leigh template guidebush adaptor. See Guidebush Chart.
