The Pinnacle SL600 has earned its name and reputation for standing above the rest. Design, Form and Function come together to make Pinnacle the most reliable, durable, and sought after stair lift on the market. What makes Pinnacle different? It’s what you don’t see, the patented Helical Worm Gear and reinforced Nylon Polymer Gear Rack. This innovative drive system eliminates maintenance, provides you savings with lower energy bills, and delivers a smooth, stable ride you can rely on.

What Sets the SL600 apart from the others

The Pinnacle SL600 seat folds up neatly, occupying a mere 10.5″ of width from your staircase wall and allowing others to pass by. The rail mounts only 0.5″ from the wall and is only 3″ tall, helping to minimize its footprint.
