American Garage Door Supply DT2A Radio Transmitter 310 MHz

Indoor Two-Channel Transmitter

This American Garage Door Supply DT2A radio transmitter operates at 310 MHz and controls up to two doors from inside the building. It uses a mechanical push-button design for momentary contact activation. A 9 V DC battery and a visor clip are included in the package. The unit is supplied new and ready for immediate installation.

Ideal for Simple Dual-Door Control

Homeowners who want a straightforward indoor remote for a pair of garage doors will find this transmitter fits the need. It does not suit installations that require more than two channels or a different operating frequency. Buyers who need weather-resistant outdoor keypads or smartphone integration should look at other product types. The momentary contact style also means it cannot hold a door open without continuous pressure.

Fits Standard 9 V Power and Visor Mounting

The transmitter runs on the supplied 9 V DC battery, so no external wiring or transformer is required. Its compact plastic housing clips to a sun visor or similar flat surface, keeping the controller within easy reach while driving. Because it communicates at 310 MHz, the receiver on each door must be compatible with that frequency. No additional mounting hardware or programming cables are included.
