Tandem SERIES We've got you covered! A Tandem Gate (also called a "Telescopic Does your driveway have Gate") is a multiple piece gate system which layers the gate sections neatly behind one another as they slide back into one compact limited space for a gate? space. This allows for almost twice the opening width to slide back into half the space. To open and close, these utilize a powerful, yet whisper-quiet, rack & pinion motor.
