This sliding patio door handle set is constructed of white painted diecast materials and a wooden handle finished in a light stain. The handle set is non-handed allowing it to be used on both left and right-handed patio sliding doors using 3-15/16 in. mounting hole centers. This handle set is used to replace damaged or missing mortise/hook style handle sets on sliding glass doors. Installation instructions and all fasteners necessary for the installation of this handle set are included in packaging. The outside pull of this handle set can be converted to an outside locking pull using Prime-Line’s model numbers C-1041 or C-1139. Product selection tip: besides matching the style and type of locking mechanism, the other main specification to match is the measurement of the mounting hole centers, from center-2-center. Note: due to numerous compatible options, the internal mortise lock body is not included with this item and must be purchased separately.
