IMPERIAL KEYSTONE – DUAL POINT LOCK FOR AMERICAN SLIDING GLASS DOORS
The IMPERIAL Keystone dual point mortise lock is compatible with all IMPERIAL sliding door handles. The Keystone has a built-in mishandling anti-slam in its collapsible hooks. Unlike other anti-slam locks in the market where the lock can only be operated when the door is engaged with the frame the Keystone dual point lock can be operated without engaging the door into the frame and can be slammed without causing any damage to the lock, the strike or the door. It also easily upgrades single point locks with very minor changes to the mortise.
The Keystone only requires a 45 degree turn to lock or unlock, a built in lock indicator with a compression hook. Opposing hook orientation provides anti- lift security and laminated hooks ensure a load capacity of over 2,000 lbs. Available in All Stainless Steel for the toughest coastal applications.
The Keystone is available in flush mount, surface mount and recessed mount making it suitable for Vinyl, Clad, Fiberglass, Aluminum and Wood doors.
