Additional bolt for sliding and patio doors.
Finish

Heavy-duty bolt for external doors.
Finish
Patio bolts are used as an added door security bolt on compatible sliding, patio, rear and external doors.
They are useful when a door needs an extra fixed locking point, a simple backup lock or added resistance against movement.
Use a separate bolt to give the door another point of locking support.
Help hold the door more firmly closed when a latch alone feels weak.
Add simple extra locking control alongside the main latch.
Patio bolt selection depends on door compatibility, bolt position, frame alignment, security level, finish and whether the door is sliding, hinged, rear or external.
Confirm where the bolt can be fitted on the door and frame.
Choose the bolt strength that suits the door.
Match the finish to the door and nearby hardware.
