The Ingenious 1011 Professional is a complete lever-operated multipoint strip with two auxiliary hooks, four adjustable rollers and a central latch and hook. The centre hook is separate from the auxiliary hooks: three hooks in total.
The specification is 35mm backset, 16mm faceplate and 92mm/62mm follower centres.
Replacement fit: compare the exact model and revision, backset, faceplate shape, spindle centres, centre-case routing and fixings, remote locking-point positions and the frame keeps. A common 16mm or 20mm faceplate is not a universal fitting standard. Match the keeps to the actual frame profile and axis.
The 92mm and 62mm follower positions are distinct from an inline split spindle. Furniture, spindle parts, cylinder length and cam must suit the actual lock revision and door thickness. Confirm the required outside-latch function rather than assuming every lever-pad arrangement will provide it.
Security and weather performance depend on the complete doorset, its specified hardware, adjustment and installation. The manufacturer lists these models within its PAS24/Secured by Design range; that does not by itself certify an existing door after a replacement lock is fitted.
The stored manufacturer drawing shows the locking-point layout for this model. Compare its dimensions with the actual door and supplied revision before machining or ordering replacement parts.
