The dovetail joint has been the hallmark of excellence for centuries. No other method of joinery offered the distinctive look and incredible strength of this mechanically interlocking joint until Leigh invented the Isoloc joint.

Leigh's revolutionary Isoloc joints represent the first entirely practical alternative to traditional dovetail joinery. With a Leigh dovetail jig and an Isoloc template, even novice woodworkers can produce strong, functional and distinctively attractive joints. Six innovative designs make it easy to match a joint style to your project.

Joint fit is controlled precisely using Leigh's patented Variable Guidebush System (VGS), a unique adjustable three piece tapered template guidebush that can be adjusted up or down, changing the joint fit in increments of .02mm.

Features include

• Precision CNC machined aluminium alloy template
• Scales include inch and metric measurements
• Fully adjustable joint tightness with the VGS
• I1 templates attach directly to the D4R and all 24"
• I1600 templates attach directly to the D1600

Standard equipment includes Leigh five piece Variable Guidebush System (VGS) with nominal 1/2" (12.7mm) outside diameter guide and a fully illustrated dual measurement user guide.
