Description
Giesse telescopic laser restrictors are designed to hold open and restrict top-hung windows. The restrictor arms are made using high-grade materials, to ensure stability when restricting and holding a window sash weighing up to 80 kg.
The window can be opened in 5 different positions. This is achieved by sliding an exclusive clip device.
To work correctly, the restrictor arm must never be fitted on the sash in a position ‘A’ higher than halfway up the sash (see technical drawing in gallery).
In addition, it is advised to position the laser arm on the frame close to the bottom corner.
This makes it possible to minimise the sash opening, and also simplifies opening and closing the sash since the higher up the arm is positioned, the greater the radius of opening the sash.
