Yale Quattro Hinged Security Door Lock no CYLINDER Black

The Yale Quattro is the fourth generation security door lock from ASSA ABLOY, engineered for hinged door applications with a projection bolt. The lockbody has been redesigned with 50% new components, delivering improved snibbing and key locking performance over its predecessor.

Key features include DualSelect™ 2-stage key locking, which lets occupants choose between privacy lock or deadlock when leaving home. The 3 Point Locking Kit operation is driven by the inside snib for enhanced security during day latching. Compatible with industry standard door preparations, it retrofits directly in place of the Tasman MK3 lockset and works with legacy Tasman MK3 accessories including cylinders, strikers, furniture, and 3 Point Locking Kits.

Designed for durability and reliability in residential security applications.
