Roto Patio Lift is our standard hardware for large Lift&Slide doors made of aluminium. It enables heavy sliding element up to 300 kg to be easily operated. We are also catering to the trend towards increasingly larger window sizes – including in the building of private homes – while also complying with the latest energy-saving and thermal insulation regulations with respect to heavy windows with the corresponding glazing. The space-saving opening of balcony doors with Lift&Slide sashes instead of Turn-Only sashes permits optimum use of space, as no sashes project into the room. Thanks to the generous window dimensions, plenty of light can enter the room thereby giving discerning and design-oriented customers a special feeling of well-being. Suitable for : - Lift&Slide systems made of aluminium frame material - Sash height and width up to 3000 mm - Sash weights up to 300 kg
