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 1222 non-keyed 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 clamp style with a surface mount and fits 4-15/16" hole spacing. The handle set fits on doors measuring 1" to 1-1/2" thick. If mounting on thicker doors, longer screws need to be purchased separately. The door handle set is constructed of diecast materials with a painted black finish, perfect for your black sliding door. Installation is quick and easy! Instructions and all fasteners necessary for the installation of this sliding door handle set are included in packaging. Due to the surface mounting, no mortising is required. The outside non-keyed pull is different in shape than the inside pull, and it can be changed to a locking outside pull using Prime-Line's model numbers E 2000 or C 1120 (purchase separately). *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.
