Dovetail Wedges

The Hoffmann Dovetail Joining System allows us to ship ready-to-assemble frames. We offer dovetail wedges on our mitered chops so you can easily assemble frames yourself instead of paying for a pre-assembled frame and the additional shipping charges usually associated with them.

How it Works

Triangular slots are routed into the ends on the back of each rail which form a butterfly shape, or dovetail, when joined. Depending on the moulding profile, 1−4 slots are made at each joint.

To join the frame, the edges are glued and a butterfly-shaped plastic piece, also known as a key, is inserted into each slot. The wedging of the keys provides the correct clamping pressure for the glue, and the end result is a tight, perfectly aligned joint with no markings on the face or sides.

This technique of joining frames has a number of benefits, a few of which we will highlight.

  • Plastic keys retain their shape and size no matter what the humidity, keeping your frame strong and properly aligned
  • Clamping, pressing, nailing, and screwing is eliminated − that saves time, money, and aggravation
  • The net cost of a ready-to-assemble mitered chop with dovetail wedges is considerably less than a pre-assembled frame

Assembly

Follow the simple steps below to put together your ready-to-assemble mitered chop with dovetail wedges.

  1. Lay the four pieces upside down on a flat workspace in the shape of the frame
  2. Apply glue to the mitered edges of two opposing pieces
  3. Gently drive a plastic dovetail key into each pre-routed slot at the joint
  4. Wipe any excess glue from the joint before it dries
  5. Repeat steps 2−4 for the remaining joints
  6. Fitting can proceed immediately − the key will hold the joint while the glue dries
