Telescopic gates basically allow twice the opening width into half the space. For example if you had a four metre opening but only two and a half metres of run off area with a standard sliding gate there is simply no way to install in this area. Using the telescopic gate kit allows the four metres to slide neatly behind the two and a half metre run off area leaving your four metres clear.
Automatic Solutions has put together all of the extra components required to install a telescopic gate into a simple kit form. You still need to add normal hardware items like track and wheels as the kit includes only the telescopic parts.
