FLEXSHAFT

Flexible shafting is a direct, mechanical method for transmitting rotary motion between two points. The Flex Shaft is 1/4” in diameter, has a brass finish, and is capable of delivering more than 50lbs of torque without damage. The flexible shaft easily avoids ceiling obstacles, making the method much easier than square, solid rod. The damper and controls are factory assembled to simplify installation and save time on the job site.
