Breakaway bottom sections are a commercial door option that are used in high traffic areas. They are designed to release from the track and swing up to a full 45° angle inward or outward if struck, preventing further damage to the door. The section can be reset in seconds to allow continued operation.
See the Break-Away Bottom Section Sell Sheet for additional information on availability and requirements.
