If your sliding glass door handle is old, damaged or missing, don’t get a brand new door – just replace the door handle! This C 1131 Sliding Glass Door Handle Set makes the DIY project a breeze. 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/hook style and fits 3-15/16” hole spacing. The door handle set is constructed of Black painted diecast materials with a light stained wood handle, perfect for your Black sliding door. The outside pull of this handle set can be converted to an outside locking pull using Prime-Line’s model numbers E 2144, 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. See sample item; Prime-Line's model # E 2014.
