Titan is the latest tilt before turn system from Siegenia for use on UPVC, timber and aluminium windows. These complete sets have been designed for new installations or replacing old TBT systems fitted to sash windows with a standard 16mm eurogroove channel. These models are to suit sash rebates between 801-1200mm high and 851-1050mm wide, with variants to suit left or right hung windows and 9mm or 13mm eurogroove axis. They also offer two types of hinges, surface fixed or for a more aesthetically pleasing look, concealed fixed hinges. Drive gears are available with 7mm or 15mm backsets. Check the backset of the old drive gear if you're replacing an existing system. These systems are supplied as complete sets to suit particular window requirements. If you are unsure this is the correct set for you, check your sash dimensions are between that of the sash rebate width and height. Further details can also be found in the Specifications. A window handle is not included in the set, see rela
