A stretcher plate is a metal plate that is used to join two parallel wooden or metal beams or joists together. The plate is typically made of steel or other metals and is designed to provide additional support and stability to the beams or joists. Stretcher plates are often used in construction and framing applications to connect two beams or joists that are too long to be supported by a single piece of material. They are installed by placing the plate over the two beams or joists and securing it in place with bolts or screws. Proper installation of stretcher plates is crucial for the overall strength and stability of the structure. Stretcher plates are an important component in building and construction and can greatly improve the longevity and durability of the finished product.
