The fixing frame is available with or without a rubber ring sealing to the duct. The aerodynamically shaped outer cone has a sealing strip on the connection to the mounting frame. The inner cone, which is suspended on a threaded bar in the outer cone, is adjustable and can be locked in position.
The cones are made of sheet steel. The mounting frame is made of galvanized sheet steel. The cones are painted.
