A handed lever-operated Winkhaus Thunderbolt lock with four remote deadbolts, a centre latch and deadbolt, split follower and 20mm radius faceplate.
These 35mm-backset locks are supplied in fixed left- and right-hand versions with a 20mm radius faceplate. Match the reference, furniture and keep layout to the door preparation.
The four remote deadbolts are separate from the centre deadbolt. Any claimed security performance applies to the documented doorset and hardware combination.
Replacement fit: match the exact supplied reference and generation, handing, backset, follower/spindle arrangement, faceplate profile, case routing, fixing holes, locking-point positions and frame keeps. PZ centres alone do not establish furniture or replacement fit. Follow the applicable fitting limits rather than trimming a strip simply because it is too long.
The stored manufacturer document is a range/system guide. Match its applicable configuration to the supplied reference; it is not an exact drawing or certificate for every older part number.
