Roto Twin Cam Security Lock

All Dendura windows are fitted with Roto Twin-cam Security Locking (TSL). This 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:

Strong

Innovative design makes the TSL one of the strongest and most reliable on the market.

Reliable

High quality finishes give TSL exceptional corrosion resistance, whilst tight production control ensures each product will last for years. The TSL also carries a 10 year guarantee to give you even more assurance.

Easy to use

Precision engineering gives TSL its smooth, effortless operation. BSEN 7950 All you need to do is simply turn the handle.

Secure

The TSL’s locking points are arranged in pairs. Each pair consists of two high strength, adjustable cams with ‘mushroom’ heads for additional security.

When you close the window, you turn the handle down into the locking position. As you do this, TSL’s unique gearbox and drive mechanism makes each pair of cams move together, locking into their respective frame keeps with a clamping action. This provides increased resistance to ‘jemmying’ in both directions.

BSEN 7950

Our traditional range casement window is accredited with BSEN 7950 (Specification for enhanced security performance of windows for domestic applications).
