Gainsborough's Sliding Patio Door Deadlocks are designed and manufactured in Australia. Suitable for most timber and aluminum sliding patio doors, Gainsborough's Sliding Patio Door Deadlocks feature modern, ergonomic styling and robust design and are backed by a 5 year tarnish resistant and 10 year mechanical guarantee.
Once the door is closed, the twin beaks are operated by key or lever to engage the catch plate.
The lock cylinder is set 37mm from door-jamb when door is closed.
Twin counteracting beaks engage an all-metal catch plate, providing resistance to jemmying and restraining the door against being lifted from its rails.
Self-adjusting catch plate automatically compensates for building movement and door carriage wear, to ensure correct latching after continued use.
A range of outer pull designs are available for various applications.
Anti-slam plunger prevents the door being shut with beaks extended, avoiding damage to beaks and catch plate.
Fits Industry-standard three-hole door cutouts (three 9mm diameter holes).
Fits wide range of door stile thicknesses from 21.3mm to 46.4mm.
Suits left-closing and right-closing doors (lock is not handed).
Australian design and manufacture.
