4-Mode Locking System Explained:

Mode 1 – Unlocked: Handle operates freely for full movement through tilt and turn positions. Ideal for window cleaning and full access.

Mode 2 – Tilt Safe (90° Cylinder Position): Tilt ventilation only, prevents full opening for fall-safety protection. Perfect for upstairs rooms and children’s bedrooms. Window can only move to turn mode after unlocking with the key.

Mode 3 – Fully Locked (180° Cylinder Position): Handle fully locked in closed position. Recommended when your home is unoccupied for maximum security.

Mode 4 – Turn First Locked: Inverted backplate for older turn-first window systems. Key must be turned to full 180-degree position to operate.

Pro Tips:

Pro Tip: Use the 90-degree Tilt Safe position for everyday ventilation in upstairs rooms. This provides fresh air whilst maintaining complete fall-safety protection—especially important in homes with children or elderly residents. Installers should demonstrate all four modes to end users to ensure the handle’s safety features are properly understood and used.

FAQ:

What’s the difference between Tilt Safe and fully locked?

Tilt Safe mode (90-degree cylinder position) allows the window to tilt for ventilation but prevents full opening for fall-safety. Fully locked mode (180-degree position) prevents any movement for maximum security. Use Tilt Safe for everyday ventilation, and fully locked mode when leaving your property.

Will this handle fit my tilt and turn windows?

The Alpha TBT has standard 43mm fixing centres and eurogroove compatibility, so it will fit all eurogroove fit systems including AGB, Roto, Siegenia and Maco hardware (with a 40mm handle spindle). It works with uPVC, aluminium and timber windows with tilt and turn drive gear. The 7mm square spindle with 40mm length is industry standard. Simply measure your current handle’s screw hole centres and spindle length.

How do I set up the handle for turn-first windows?

For turn-first operation, invert the backplate during installation. This changes the locking behaviour so the key must be turned to full 180-degree position to unlock—there is no intermediate Tilt Safe option in this mode. If your current handle turns down first before tilting, use the inverted backplate configuration.

Which finish should I choose for my window frames?

For white uPVC frames, choose White or Polished Chrome. Black, Anthracite Grey and Enduro Steel match grey or black frames. Satin Chrome is modern and will work across multiple colours. PVD Gold is elegant and perfect for traditional properties.
