Lift N Slide Door

A type of multi-slide patio door, a lift/slide, for those who aren't familiar, is a door that uses special hardware allowing the panels to lift off their track and weather-stripping and glide open or closed. When it's time to close the glass doors, the handle lowers the panels on the track for a tight fit.How do lift and slide glass patio doors work? There are rollers connected to the locking mechanism of the door so that when you lift the door handle, the door will raise, allowing the rollers to run along the track underneath the door.
