Multi Sliders open to two-thirds of their width so they’re ideal where generous opening to the outside is needed. Two formats are available -- a three-panel unit with two stacking panels or an ultra-wide six-panel unit with two panels stacking towards one jamb and two stacking towards the other. It is common practice to include opening sashes in sidelights for ventilation purposes. The suggested maximum size for sliding panels is 1200mm wide by 2400mm high. Lock options include surface-mounted types such as the Albany lock, or the Miro handle and morticed lock.
