Altus® Window Systems introduced the Ranchslider® in the 1950s, revolutionising the way New Zealanders connect their indoor and outdoor spaces. As the pioneer of sliding door technology, Altus® Window Systems has continued to innovate, ensuring that the Ranchslider® remains the gold standard for smooth operation, durability, and modern design.

A classic kiwi design, Built for today

The Ranchslider® sliding door is a timeless favourite, featuring sliding panels that move effortlessly behind a fixed panel – maximising access and unobstructed views. With its versatile configurations and modern enhancements, the Ranchslider® continues to set the benchmark for sliding door excellence.

Remove all potential trip hazards by upgrading to the optional Levelstep™ Sill which provides a flush level entry.

For even greater flexibility, the Ranchslider® is also available as a stacking system – the Ranchstacker™. Instead of sliding behind a single fixed panel, multiple panels can stack neatly together, creating a wider, more open transition between indoors and outdoors. The Ranchstacker™ is the ideal choice when you want to maximise flow, light, and access without compromising on the signature smooth operation and enduring quality that has made the Ranchslider® a Kiwi favourite for generations.
