Just ask Secret Service: the best security is unobtrusive and stylish. And that s exactly what you get with the Simtech sliding-gate opener. Operating gates that weigh up to a tonne, it opens your home to you and you alone. Simply press the radio remote when you get within 30 metres, and the Simtech will welcome you in on its ultra-quiet, nylon-reinforced racks. This gate comes equipped with a safety feature to prevent significant injury to person or any other precious possession. If the gate comes into contact with an obstruction, it reverses back into the open position.
