Gearing - Locking
Solartherm® Tilt & Turn Windows are fitted with Twin Cam Security Locking System (TSL), the TSL is one of the most revolutionary and secure systems on the market, it has up to eight locking points with adjustable twin-cams offering even greater security against burglary. The unique gearing mechanism operates the reverse-action twin cams, all cams engage in behind individual recesses on both sides of the striker, attempts to force one cam out of its locked position only drives the other cam deeper in to its recess.
The PN Uni Top Swing gear is used in Sidey Solartherm® fully reversible windows. The gearing, which is concealed when closed, allows the window to be fully reversed for safe cleaning from the inside, with all the movement taking place outside the frame.
