This replacement set is designed for sliding patio doors and provides a complete hardware upgrade without replacing the entire door. It includes an interior handle, exterior pull, mortise lock, thumb latch, and six screws tailored for common door configurations. The handle set is reversible and non-handed and can be mounted on left or right handed doors, adapting to different swing directions. The Forty-Five degree mortise latch lock works with wood, aluminum, and vinyl frames, delivering consistent engagement along the edge of the door. Installation is framed as a do-it-yourself project: remove two screws from the existing handles, insert the latch, align the inside and outside handles with predrilled holes, insert screws, and tighten. Six screws are provided in three sizes: large, medium, and small to accommodate varying door thicknesses and mounting needs. The exterior pull is non-keyed and cannot be converted to a keyed function at this time. This kit is intended for straightforward replacements of worn or broken components, preserving the existing door structure. It suits doors that open from either side and helps maintain a secure, functional latch without major modifications. Basic tools and careful alignment are all you need for a reliable setup. The parts are designed for standard door thicknesses and common screw spacings. Color: Black.
