4-Mode Opeartion

Fully Locked (Key turned 180°)
The handle is locked and the window cannot open in any position. For maximum security when the property is empty.
Tilt Safe (Key turned 90°; backplate shows TS)
The handle opens to the tilt position only – ideal for secure ventilation. The window cannot fully open, preventing accidental falls.
Unlocked (Key at 0°; backplate shows TS)
The handle moves freely from closed to tilt and then to turn, allowing for full sash egress.
Turn-First Mode (Inverted backplate shows TF)
Designed for older turn-first windows. The handle must be turned the full 180° to operate.

Did you know? TBT handles look similar to standard Espagnolette handles but are built much more robustly. Espag handles operate simple side- or top-hung windows with a single action, while TBT handles must drive a complex, multi-point locking system to deliver two distinct opening modes—tilt and turn. The result? A stronger handle engineered to handle significantly more friction and force, every day.
