The new Yale Quattro® is the fourth generation of ASSA ABLOY’s security door lock with projection bolt, to suit hinged door applications. While the lock may look familiar, the lockbody has been redesigned and incorporates 50% new parts from its predecessor to improve the operation and durability of the snibbing and key locking functions.

• Improved snibbing and key locking functions.
• Compatible with industry standard door preparations and will retrofit in place of the Tasman MK3 lockset.
• Can be used with legacy Tasman MK3 accessories such as cylinder, strikers, furniture and 3 Point Locking Kits.
• 3 Point Locking Kit operation is driven be the inside snib for increased security when “day latched”.
• DualSelect™ 2 stage key locking, offers safety and security for all occupants by giving a choice of selecting privacy lock or deadlock when exiting the home.
