  • AC26S: tempered glass with CNC engraving, with an optional CNC-engraved rear lock.

Who the AC series is for

The CNC-engraved finish is chosen when the lock is a visible part of the interior or the brand: premium apartments, showrooms and villa projects. Buyers who sell on features alone usually start with the A series. Buyers who sell on design often start with the AC series and add OEM options such as logo, language and packaging.

Options to ask about

  • The CNC-engraved rear lock, available on the AC series.
  • TTLock or Matter versions, and the interface language (up to 23 languages on supported versions).
  • Rear lock options 6085, 6090 or 5072 for the door you need to fit; check your door with the lock body compatibility guide.

The AC series is packed 6 sets per carton at 49.5 x 34.5 x 52.5 cm; see how many fit in a container. To discuss samples and OEM options such as logo and language, contact us on WhatsApp.
