Mechanical locking cylinders
Double cylinder
Locking cylinders form the core element of secure
locking systems and represent IKON?s core
competency. The product range meets challenging
security requirements with sophisticated solutions.
High-quality IKON locking cylinders provide high
protection against intruders and a huge amount -
related to the cylinder type - are certified to meet
appropriate standards. Standard equipment in this
respect includes anti-drilling devices, security cards and
panic functions. Patented profiles are a direct result of
decades of experience gained in precision engineering
and are effectively equipped against even the latest
intrusion or burglary techniques. These features include
innovative VECTOR profiles and the IKON reversible key
profile WSW-W10.
Area of Application
Double cylinders that can only be actuated from one side are
generally used for entrance doors with a lower security
requirement , or due to building conditions. IKON double
cylinders are available in different lengths to meet the needs
and requirements of every installation situation. There is a
choice of different design variants. It goes without saying that
you can also obtain several keyed alike locking cylinders, so
that only one key is required for several doors.
