A through mortice and tenon joint connects two pieces of wood at a 90 degree angle by cutting the mortice right through one piece, with the tenon inserted and cut flush. It is a popular woodworking joint due to its strength, and is a common choice for making frames such as bed frames, doors and windows.


What is a mortice and tenon

Dating back thousands of years, it is one of the oldest ways to join two pieces of wood. It comprises a mortice hole and tenon tongue which fit exactly into one another.

It’s a versatile joint that can be used in many different types of woodworking, from fine furniture to large oak framed buildings.

Most of the strength from this joint is in the downward motion. It's not a strong in the pulling direction like a dovetail joint is.

There are three types is, a blind, a through, and a wedged mortice and tenon.
