How is a bridle joint formed?

• A. A joint formed by fitting the end of one member, notched to form two parallel tenons, into two gains cut into the edge of a second member
• B. A joint created by shoemaking adhesives
• C. A mortice and tenon joint without the shoulder
• D. A loose-fit joint with pins

Answer: (A)

A bridle joint is a type of mortise-and-tenon connection where the end of one piece is cut back to form two parallel tenons, which fit into two corresponding mortises cut into the edge of the other piece. When the pieces are joined, the tenons slide into the mortises and the large shoulder surfaces on both pieces create a strong, stable corner with plenty of glue area. This setup is especially useful for sturdy frames or gates where a robust right-angle joint is needed. The other options describe different methods or purposes (adhesives, a simple mortise-and-tenon without the shoulder, or a loose-fit with pins) and do not convey the two-tenon/dual-mortise arrangement that characterizes a bridle joint.
