Operation and dimensions of this version

10T31402012 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 14 positions; check the starting angle and lock-body drive requirements when matching components.

Key system and installation checks

Tekno iNOVATE key part number is 1.00690.10.0, with blade length 16 mm and thickness 2.9 mm. Its plug contains bilateral steel control pins and hardened-steel driving pins of different shapes; Checking key dimensions and checking the lengths of both cylinder sides are separate steps.

When selecting, first record nominal size 30/10 for 10T31402012, 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.
