The supplied GU Europa inboard 6-32598-0101 has a central latch and deadbolt with two hooks and two rollers. The retained specification is 35mm backset, 92mm PZ centres and 16mm faceplate.
Europa operation: with the door closed, lift the handle to extend the secondary locking points and main deadbolt. Turn the cylinder key to secure the mechanism and block the handle. Unlock with the key before lowering the handle to retract the mechanism and latch. The key secures the already-extended main deadbolt; it is not the action that first throws it.
This listing retains the supplied inboard reference. Identify the version by its exact code, actual locking-point layout, case and drive connections. Do not select it on an assumed deeper gearbox or clearance difference without the applicable manufacturer drawing.
Hooks and mushroom points engage their matching keeps; rollers provide closing compression. Correct seals, adjustment and alignment determine weather performance. A replacement mechanism is not a repair for a warped or misaligned door and does not by itself establish thermal, acoustic or weather ratings.
Replacement fit: compare the exact supplied reference and generation, backset, PZ centres, follower/spindle arrangement, faceplate profile, case routing, fixings, locking-point positions and frame keeps. Shared GU branding or 92mm centres alone are not a direct-fit guarantee. Spindle and cylinder selection must also match the furniture, door thickness and required outside operation.
