These transmitters make the perfect solution for your gate opener because they feature HID Proximity Tags that alert the system that you're in the proximity of the gate with added security benefits that many transmitters do not have. Make sure to check the transmitter before purchase to make sure that it matches your particular needs and model. If you don't see the style you need, we can always order it for you. Just send us an e-mail or give us a call at 800-783-6112 and we'll place your order fast. North Shore Commercial Door typically ships products on the same or next business day.
