Operation and dimensions of this version

The knob shaft illustrated for 10X3M218012 is on side B; Body B=39.5 mm, key side A=39.5 mm; L=79 mm excludes the projecting knob shaft. The knob is an operating component to verify separately; a shaft configuration does not mean that a complete knob is supplied. This row is explicitly identified as modular in the catalogue; for extensions or repairs, check the corresponding connectors; modules from other series cannot simply be substituted.

Key system and installation checks

The catalogue key part number for RX is 1.00830.00.0, with blade length 16 mm. Although the body dimensions can match RS5, the key systems and catalogue part numbers differ; they cannot be treated as key-interchangeable substitutes; Duplicate keys must correspond to the original system.

When selecting, first record nominal size 40/40 for 10X3M218012, then verify the actual 39.5+39.5=79 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.
• The catalogue lists series 06353, 06355, 06356 and 06357 knobs as available on request, not as standard equipment for this row.
