Three-Point Lock
Top, center, and bottom locking points for common exterior doors.
Multipoint locks engage a panel at several points along the frame through one handle or cylinder operation. They improve seal compression, panel alignment, and security on tall doors, hinged patio doors, casements, and tilt-turn systems. Specification requires close coordination of backset, handle height, lock case, shoot bolts, hooks, rollers, keepers, and manufacturer routing templates.

Details To Confirm Early
01
Verify compatibility before ordering
Backsets, handing, mounting holes, routing templates, and manufacturer-specific parts must match the door or window system.
02
Account for exposure
Coastal, pool, commercial, and high-humidity environments need upgraded corrosion resistance and finish durability.
