What is Mortise And Tenon?
Definition of Mortise And Tenon in Construction A form of joinery that is used on window and door assemblies to improve strength and longevity. The joint is made by cutting an opening in the receiving member, called a mortise, and then cutting a tenon in the adjoining piece, to allow insertion of the tenon into the mortise. Normally glue is used to secure the pieces together. The mortise and tenon method of assembly has been in existence for several centuries and has withstood the test of time. There are special tools that are available to accurate cut both the mortise and the tenon, however, there are also specialty craftsmen who are capable of establishing these joints by hand. The mortise and tenon, if performed properly, is one of the strongest joints possible and will last without loosening for centuries.
