This C 1225 sliding patio Door handle set makes the DIY project a breeze, and it includes an inside pull with an outside non-locking pull. Installation is quick and easy, all fasteners necessary are included, and the set is non-handed, allowing it to be used on both left and right-handed patio sliding doors. It is a mortise style and fits 3-15/16" hole spacing. The door handle set is constructed of white painted diecast materials, perfect for your white sliding patio door. Because there are multiple internal mortise locks that are compatible with this handle set, a mortise lock component is not included with this handle set. Although the C 1225 sliding patio Door handle set comes non-keyed, Prime-Line Products does manufacture other components that can convert this set to a keyed-locking handle set.
