The new Twin Cam Security locking system from Roto is now available from Frame Fast. A new breakthrough in window locking systems, the new TSL is one of the strongest and most reliable locking systems on the market, offering more than double the security of industry standard products.

With a simple turn of the handle, TSL’s unique gearbox activates up to four pairs of high strength, ‘mushroom’ cams, which simultaneously drive 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.

The TSL offers exceptional resistance against corrosion and carries a 10 year guarantee. See the new TSL system in action at the trade counter.
