Operation and dimensions of this version

10A3S1700 is a double cylinder with clutch: A=54.5 mm, B=54.5 mm, with the two sections totaling L=109 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

The dual-material reinforcing core in this series uses segmented components along the cylinder length; this is a feature of the body construction. The catalogue lists Code Card; this does not establish key interchangeability with other Astral series.

When selecting, first record nominal size 55/55 for 10A3S1700, then verify the actual 54.5+54.5=109 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.
