The Inline vent draft blocker is suitable for retrofitting since the 4 inch backdraft damper completely fits inside the duct.PREMIUM MATERIAL The housing of 4 inch duct damper flap is made of galvanized steel. The 4 backdraft damper blades are made of aluminum, while the axle and spring are made of stainless steel. Tight sealing and fastening of the duct are achieved by the rubber strip attached to the outside of the backdraft damper 4 inch.MULTI-USE Designed for use in AC, dryers, exhaust, extractor or range hoods, heating systems, vents, and other residential, commercial, and industrial HVAC applications. The rubber seal prevents loud rattling when the flap blades open and close.PERFORMANCE Duct blocker prevents cold air or wind from entering the ventilation pipe. In this case, the flap is installed in such a way that the flap leaves only open into the outgoing air direction.

The position of the spring should be horizontal when the flap is installed horizontally so that it can be opened and closed optimally. This also applies to the vertical installation.
