With SecuForte, HOPPE offers a completely new standard in burglary resistance: In both the closed and tilted positions, the handle and square spindle are decoupled, and the handle is automatically locked - a unique protection concept that effectively prevents unauthorized opening of the window from the outside. Advantages include protection against break-ins through glass drilling, frame drilling, or moving the fittings from the outside, an automatic locking function in the closed position (0°), burglary resistance even in the tilted position (180°), RAL certification, and a length-variable square spindle VarioFit®.
