Roto Twin-Cam Security Lock (TSL)

Twin-cam Security Locking (TSL) 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:

• Innovative design makes TSL one of the strongest and most reliable locking systems on the market.
• High quality materials and finishes give TSL exceptional corrosion resistance, whilst rigorous production control methods ensures that each product will last for many years. TSL even carries a 10 year guarantee to give you added assurance.
• Secured by Design and BBA approval.
• Precision engineering gives TSL its smooth, effortless operation.
• With a simple turn of the handle, TSL's unique gearbox activates up to four pairs of high strength 'mushroom' cams. Each pair of cams closes together, utilising both sides of a security striker. This double action locking significantly enhances resistance to jemmying from all directions and strengthens the window's security.
• TSL suits all of the industry's popular window systems.
• TSL can be used to replace most standard locking espagnolettes to improve security.
• Low handle height versions available: ideal for side hung windows where a lower handle is required.
