Automatic Door Bottoms: Seal Gaps, Block Air, Smoke & Noise | Legacy Manufacturing

Whether it’s smoke from a fire, summer heat, or unwanted pests sneaking in, even the smallest gap beneath a door can make a big difference. At Legacy Manufacturing, our automatic door bottoms (ADBs) are designed and built using proprietary rubber and high-quality housings for superior performance and durability, even under the most challenging installed conditions. As the door closes, the plunger compresses against the door frame, activating a spring mechanism that lowers the rubber seal in a smooth, scissor-like motion. This creates an uninterrupted seal along the floor, while the self-leveling design ensures a tight seal even on uneven surfaces. With over 6 million cycles of testing, a wide range of finishes, and specifiable custom sizes available, our automatic door bottoms are engineered to meet the demands of various architectural applications.
