Operation and dimensions of this version
10Q31129012 is a double cylinder with clutch: A=44.5 mm, B=44.5 mm, with the two sections totaling L=89 mm. The two sections are equal; still check whether the escutcheons leave the actual length requirements on both door sides symmetrical.
Key system and installation checks
This series has key blade length 17 mm and thickness 2.9 mm; Personal Card is also listed. Key dimensions can help check the entry clearance of a protective escutcheon; they do not establish key interchangeability between systems.
When selecting, first record nominal size 45/45 for 10Q31129012, then verify the actual 44.5+44.5=89 mm against the drawing. Nominal size is an ordering identifier; adding its two integers does not give the actual overall length.
Limitations
- Dimensions are divided at the central reference in the catalogue drawing; a and B do not automatically designate the outside and inside of the door. Installation also requires checking the lock-body cam interface, door thickness and escutcheon thickness.
- Catalogue model numbers and dimensions do not establish current stock availability or certification of the complete door; Before purchase, check the actual supplied product's identification plate and the manufacturer's installation documentation.
