Comprehensive Single Door Kit: This kit includes two high-performance sensors with pre-installed wires, ensuring a seamless installation process. Additional wire connectors are also provided to facilitate hassle-free installation. Enhanced Mechanism: Our sensors project an invisible beam across the garage door opening, and if any interruption is detected, it automatically reverses the garage door. This critical feature helps prevent unnecessary accidents and ensures the safety of your vehicle and loved ones. Exclusive Compatibility: Designed specifically to be compatible only with linear garage door openers, including models HAE00002, LSO50, LDO33, and LDO50, ensuring a perfect match and optimal functionality with these specific models.

Our sensors are designed specifically for use with specified linear garage door models, ensuring proper fit and functionality with your specific garage door system.
