KFFKFF AC800 Sliding Door Opener - 1800 lbs Capacity, 43 ft/min, 2 Remotes (Base Model)

Bring automated convenience to heavy sliding doors with the KFFKFF AC800. This chain-driven opener is built for use in homes, commercial complexes, schools, hotels, farms and ranches, and helps secure your property from unwanted entry. Operation is remote and simple: two handheld remotes let you open, close and stop the door from up to 100 feet away, and two manual release keys are included for use during power outages. The unit features an automatic close function with selectable delay times of 5, 10 or 20 seconds. Heavy-duty performance comes from a quiet 360W pure copper motor capable of moving 1,800-pound doors at 40 feet per minute. Durable construction includes a waterproof housing and a 9-inch high base to reduce flood risk. Safety features include a temperature protector that adjusts thrust to avoid motor overload and obstacle-detection that stops and reverses the gate if it meets resistance. Everything needed for installation ships in the box: a 20-foot track chain, all mounting hardware, a hex wrench and a detailed instruction manual—pre-packaged for straightforward setup.
