The frame of the side sliding sectional door is easy to screw together and can subsequently be fastened completely to the garage wall. Fitting in tight areas with only 140 to 450 mm sideroom is made possible with the DS track application (see the illustration on the left) with double side guide rails. Precise door travel Twin rollers made of wear-resistant plastic move reliably and precisely on the aluminium rail and prevent the door sections from jumping out. They also make the door move quietly and easily, making it a breeze to operate the door by hand as well. Stable connecting hinges on the rollers and between the PU-foamed 42-mm-thick sections ensure good door leaf stability.
Flexible and weather-resistant seals on the sides and in the lintel area of the door frame keep out the wind and rain. The side seal optimally fills the door gap with a large-sized profile lip. Seals between the individual sections and at the bottom edge also provide for good door sealing.
The bottom and top door guide close the door precisely. Two additional hooks on the side of the door firmly connect the end of the door leaf with the side frame. This mechanical lock is also practical for preventing the door from being forced open. To improve break-in resistance, doors can be optionally equipped with 3-point locking at the closing edge.
The aluminium floor rail reliably guides the door sections and prevents the sections from swiveling out. A flat design of only 25 mm makes it easy to drive in and out. It is easy to clean out dirt and leaves from the rail, as it is open on the ends.
