The Alpha TBT handle from greenteQ is a premium quality product that features the modern appearance of its Alpha stable mates. This means that tilt and turn windows can be suited with casement windows and residential doors on the same installation. Standard 43mm fixing centres make the Alpha TBT handle suitable for all eurogroove fit tilt and turn hardware systems, including the AGB and Roto ranges that are also covered by Q-secure.
The lockable Alpha TBT handle has four settings:
1 – Unlocked – The handle will permit free movement from closed, through tilt and into the turn position to allow the external face of the window to be safely cleaned from the inside.
2 – Tilt Safe – With the cylinder turned to 90 degrees, the handle permits free movement to the 90 degree tilt position. This allows tilt ventilation, but the window cannot be fully opened, preventing falls. Once the handle is unlocked using the key, the window can be opened to turn mode.
3 – Locked – With the cylinder in the locked 180 degree position, the handle is fully locked, and the window cannot be opened in any position. For security reasons, this is the ideal state for the handle to be left in when a home is empty.
4 – Turn First Locked – By fitting the backplate inverted the handle can be locked in the bottom position as normal. However, the user will not have the option of turning the key to only 90 degrees. It must be turned to the full 180 degrees to allow the handle to operate, making it suitable for fitting to older turn-first windows.
