Operation and dimensions of this version

10M32402012 has key operation on one side only, A=29.5 mm, with the other section B=10 mm; Nominal size 30/10 must not be interpreted as a double cylinder accepting keys on both sides. The cam adjusts to 8 positions; check the starting angle and lock-body drive requirements when matching components.

Key system and installation checks

This series uses controlled-break cuts and bilateral steel control pins. Security Card is used for protected key duplication; it is not proof of universal key compatibility.

When selecting, first record nominal size 30/10 for 10M32402012, then verify the actual 29.5+10=39.5 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.
