KFFKFF AC1400 Sliding Door Opener — 3100 lbs Capacity, 43 ft/min, 2 Remotes (Base Model)

Heavy-duty, chain-driven opener engineered for sliding doors up to 3,100 pounds. The KFFKFF AC1400 base model ships with two remote transmitters and two manual release keys; the remotes control open, close and stop functions from up to 100 feet. An automatic close feature is included and can be set to 5, 10 or 20 seconds after opening. Installation is simplified with a 20-foot track chain, complete installation hardware, an installation manual and a hex wrench—everything packaged for straightforward setup. The unit is suitable for residential and commercial settings including homes, gated communities, schools, hotels, farms and ranches. Power comes from a quiet 500W pure copper motor housed in a waterproof casing that resists dust and corrosion. The motor is capable of moving 3,100 pounds at 40 feet per minute. A 9-inch high base helps keep the opener above floodwater during heavy rain. (Rated travel speed: 43 ft/min.) Safety and durability features include a temperature protector that adjusts motor thrust to avoid overload, plus obstacle detection that stops and reverses the gate if it encounters resistance during opening or closing.
