Roto’s Twin-Cam Security Lock (TSL) has been design to provide a high level of security for outward opening windows, with specific protection against jemmying.
The one piece espagnolette features up to four pairs of dual reverse action locking points. When the handle is turned, the gearbox drives each pair of cams into double sided strikers from opposite directions. This ensures maximum burglary protection defined in PAS 24:2012.
In addition, the strikers are fixed to the profile with two screws which prevent the former from twisting, even in the event that a great force is applied.
The eccentric cam design not only increases burglar-resistant security, it also provides greater gasket compression. The striker also features a night vent facility.
For difficult to reach windows, the TSL low handle height variant would be ideal. The central gearbox is offset at 205mm from the bottom of the espagnolette to allow a lower handle height to be achieved for side hung windows.
