This mortise style patio door handle set is constructed of diecast material. It includes an inside pull with an outside non-locking pull. The inside pull projects a total of 1-7/8 inches towards the inside of the home. It features a white diecast thumb turn with a durable steel latch activator. It comes in a painted white finish and fits on 1-1/2 in. (3.8cm) to 1-3/4 in. (4.4cm) thick doors. The exterior diecast pull also comes in a painted white finish and although it comes non-keyed, Prime-Line Products does manufacture other components that can convert this set to a keyed-locking handle set. The handle set mounts on the surface of the sliding door frame via two mounting holes that set are spaced apart at 3-15/16 in. (center to center). This item is a reversible, non-handed handle set that can be mounted on both left-hand and right-handed sliding doors. This patio door handle set is used by many patio door manufacturers. All fasteners necessary for installation of this item are included within packaging. 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. Color: Bronze.
