The translating slide is an excellent solution for medium-sized openings: in fact, it is a mechanism that can be installed on the patio door design that allows, once the handle is turned and the sash is pulled toward it, the sliding opening instead of reaching into the room.
Instead of a low threshold, the floor-to-ceiling sliding door features a frame, which is then lap four sides around the entire perimeter of the opening.
The floor-mounted frame and closing as a patio door mean that translating slides are widely used in window holes that are particularly exposed to water.
