Roto TwinCam Security Locking
The TwinCam Security Locking (TSL) system from Roto is a major breakthrough in window locking systems, offering more than double the security of industry standard products and giving you a host of reassuring benefits.

Its innovative design makes TSL one of the strongest and most reliable locking systems on the market. High quality materials give exceptional corrosion resistance to give you added assurance.

TSL is also easy to use. With the simple turn of the handle TSL's unique gearbox activates up to four pairs of high strength, 'mushroom' cams, simultaneously driving each cam into a double-sided security striker from opposite directions. This double action locking means that any attempt to force one cam out of its closed position merely forces the opposing cams deeper into their strikers, strengthening rather than weakening the system's security.
