CAL LOCK Doublex Patio Sliding Door Lock


The CAL double-bolt lock works by securing the door to the frame at two security points and preventing any movement of the door. With its double locking action, the CAL double-bolt lock makes it virtually impossible to remove the door by lifting off its track.

The CAL double-bolt lock can be used as a secondary or primary locking system on glass sliding doors. The lock can be mounted above the OEM lock to be out of children’s reach or below the OEM lock to be within children’s reach. The lock can also replace the OEM lock with the addition of the OEM replacement cavity. A CAL door handle is also an optional accessory and is available as an add-on to the double bolt lock. The handle can be bolted on top of the double bolt lock for easier operation of the glass sliding door. Please call us to enquire about the CAL handle.


  • Double pin to prevent the door from being lifted or forced open
