A handed lever-operated Winkhaus Thunderbolt lock with four remote deadbolts, a centre latch and deadbolt, split follower and 16mm radius faceplate.
This family contains 35mm-backset left- and right-hand versions with a 16mm radius faceplate. Match the handed reference, spindle arrangement and full locking-point layout to the existing door.
Security performance depends on the tested doorset and matched hardware. The four remote deadbolts are additional to the centre deadbolt.
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.
