Traditionally used by sailors when working aloft or over a ship's side, a bosun's chair (or boatswain's chair) is a one-person swing seat secured by a three-rope system — two for support and one for safety.
Used on buildings up to 300 feet, bosun's chairs offer mobility for our professionally trained cleaners; they are reliable in a variety of weather conditions; and they have the ability to get into corners for a thorough job.
While operators can't clean as many windows at once (compared to a swing stage), it takes less time to get bosun's chairs up and running and they create less disruption to operations.
Safe and comfortable for trained operators, these chairs are easily maneuvered and are equipped with fall arrest devices. Cleaners lower themselves into place and lock off the ropes when they reach the level they need.
