Our mending plates are thick, strong, zinc-plated and available in various different types including one with staggered holes designed to reduce the possibility of wood splitting. All holes accept our self-tapping, Phillips screws. Use these plates on larger or older frames to strenghten and repair sections, corners or where recutting and rejoining the mitres is not practicable because of instability, age, resizing problems, etc. Also used for heavy-framed objetcs such as mirrors to add support to the corners.
