The ISEO F3 construction insert provides a basic level of security for entrance and interior doors in buildings, renovations, or temporary installations. Thanks to the nickel-plated finish, it stands out with higher wear resistance and long service life.
The 40/50 model (overall length 90 mm) is suitable for standard door hardware and is supplied with a set of three keys, covering common needs of users and tradespeople. Easy installation and the universal size make it a great choice for a quick cylinder replacement during construction work.
