Description
This pneumatically operated opening mechanism for installation in skylight domes or arcade arc dome skylights can be easily installed by hanging it from above in the curb/frame.
The traverse design means that only low forces are transferred to the curb and the vent frame. Thanks to its flat design, the fitting is particularly space-saving.
The skylight dome is locked in the closed position by the mechanical locking device MHV and an adjustable locking T-shape bolt EVB3-M12.
The opening mechanism is adjustable and can therefore be adapted to the structural conditions ex works. Please enclose the dimension sheet with your order.
