The adjustable brake stay limits the rotary opening function of the window and acts as a firm brake against independent or inadvertent opening or closing. The sash brake allows you to lock the window is any opening position protecting both the window and the hardware. Without operating the brake the window is still openable to 100 degrees.
Benefits for users:
• Individually adjustable opening width: locks the sash in the desired position
• Holds the window sash in the open position even in strong draughts, for example, when airing the room
• High level of functional reliability due to overload protection
• Fully concealed
• Easy to retrofit
