BackBackThe F90 SPI cylinder with protected duplicate keys is a patented vertical locking system. The F90 SPI cylinder is also available in different locking and keyed alike versions.
The F90 SPI with a large number of different mechanical profiles available, combines excellent potential for the creation of master key systems according to the security standards.
F90 SPI has 6 encryption pins in the inferior coding row and up to 4 in the lateral coding row; the pins are made of wear-resistant special brass, per locking side. The patent SPI -valid until 2036 - and the trademark protection are registered at the Patent and Trademark Office. An anti-pick protection is integrated in the profile cylinder. Three overlapping profile ribs of the plug increase the the security of the profile cylinder against unauthorised openings (paracentric key profile). The keys are made of nickel silver. The surface of the cylinder body is matt nickel-plated or brass as standard.
