The mechanics of the hardware system incorporated in this range allow for a wide selection of shapes which are able to support large weights. Whatever the shape, the multipoint locking system provides locking points around the sash.
Closed: Concealed hinges and locking system.
Half: The mechanics of the pivot hinge ensure that the sash pivots around its centre of gravity. Therefore the heaviest of sashes can be rotated with minimum effort.
Full: The 180 degree movement can be achieved with almost any shape that is symmetrical along the pivot axis.
