As of 2015, dovetail jigs are sold at several home centers, woodworking retailers and woodworking product suppliers, such as Harbor Freight, MLCS, The Home Depot, and Rockler Woodworking and Hardware. Other retailers include Highland Woodworking and Woodcraft.
A dovetail jig is a woodworking implement used to guide a router bit along a wood surface to create joints to connect two pieces of wood. Although it is primarily used to join wood at 90-degree angles, it can be used to join wood end-to-end. Dovetail jigs are often used to create attractive yet extremely strong joints in the construction of boxes and drawers.
