Operation and dimensions of this version

10P3S141012 is a double cylinder with clutch: A=29.5 mm, B=64.5 mm, with the two sections totaling L=94 mm. The sections differ by 35 mm; overall length alone does not permit substitution with a symmetrical cylinder or reversal of the two sections.

Key system and installation checks

AP4 S key part number is 1.00810.00.0; it has a long neck to accommodate protective escutcheons. The series includes carbonitrided-steel pins and differently shaped driving pins; Security Card is used for protected key duplication; it does not establish compatibility between different systems.

When selecting, first record nominal size 30/65 for 10P3S141012, then verify the actual 29.5+64.5=94 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.
