Frameless automatic doors have become even less visible with the new slimline designed NGU model manufactured by the Australian automatic door company ADIS Automatic Doors .

With the NGU system fitted to structural toughened glass through cylindrical patch fittings the effect is one of a totally seamless entranceway.

The low transom height of the NGU door operator is the result of years of product design and development aimed at making the most compact door operator without compromising on performance and strength to move large doors, trail tests show the NGU resilient after 1.5 million cycles with door weights over 260kg.
