I order and received a different 5" damper bade by ECOPRO originally but there were two springs on the 5" damper flaps, and it took quite a force to push open the flaps, so I ended up returning that and ordering the Neverest® RK 5" Backdraft Shutter Damper. The damper opens with a minimal amount of pressure and the quality of the unit is great. My issue was that we have a down draft cooktop and when there was a descent amount of wind outside, we would get a flow of cold air (IT was in the early spring) blowing out the downdraft grill on the cooktop, so I needed to prevent the wind draft from blowing into the ducting from outside. I installed the Backdraft Shutter Damper in a 5" metal flexible duct, and it took about 45 minutes from start to finish to complete the job. Now even with the slightest outside breeze the damp shuts and does not allow any draft into the house! Review: Good Quality- Worked For City Code Inspection Requirement For Outdoor Commerical Dryer - Good Quality- Worked for City Code Inspection Requirement for outdoor Commerical Dryer. Install straight forward with arrows as directed for flow / operation of ducting flapper. Installed with very short sheet metal screws to prevent lint build up inside ducting.

It's 3.5 inches deep and can withstand temperatures from 14 to 140 °F. This air duct damper effectively prevents air from entering through the ventilation duct. - AUTOMATIC OPERATION The 6 inch duct damper backflow flap opens and closes effortlessly at low air volumes. It includes a smooth-running spring and an internal foam strip to prevent blade rattling. Can be installed horizontally or vertically. - VERSATILE APPLICATIONS This inline vent draft blocker is ideal for air conditioners (AC), dryers, exhaust and extractor hoods, heating ducts, vents, and various HVAC systems. - QUICK SETUP Install the dryer vent damper by inserting it into the ventilation pipe. Position the spring horizontally for optimal opening and closing in horizontal installations. Ensure damper blades open only in the outflowing air direction. - NOTE Our backdraft exhaust fan damper is suitable for both flexible and non-flexible ventilation ducts. However, it is essential to install them exclusively in metal ducts. Before purchase, measure the diameter of your duct to ensure compatibility. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B011IUUK96 | | Best Sellers Rank | #90,716 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #136 in HVAC Ducting #2,476 in Pipe Fittings | | Brand Name | neverest | | Color | Silver | | Connector Type | Trap | | Customer Reviews | 4.5 4.5 out of 5 stars (2,018) | | Exterior Finish | Galvanised steel | | Global Trade Identification Number | 04054503005327 | | Item Dimensions | 3.46 x 5.91 x 5.91 inches | | Item Weight | 209 Grams | | Manufacturer | neverest | | Manufacturer Warranty Description | 2 years | | Material Type | Alloy Steel | | Model Number | 4054503005327 | | Number of Pieces | 1 | | Size | 6 Inch | | Thread Size | 6 inch | | Thread Type | Metric Tapered | | Unit Count | 1.0 Count | ## Product Details - **Brand:** neverest - **Color:** Silver - **Connector Type:** Trap - **Exterior Finish:** Galvanised steel - **Item Weight:** 209 Grams - **Item dimensions L x W x H:** 3.46 x 5.91 x 5.91 inches - **Material:** Alloy Steel - **Size:** 6 Inch - **Thread Size:** 6 inch - **Thread Type:** Metric Tapered ## Images ![neverest® RK 6" Professional Backdraft Shutter Damper Connector Duct Fits Only with Metal Ducts - Image 1](https://m.media-amazon.com/images/I/61R-zDPpQKL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Neverest® RK 5" is an Excellent duct damper and Works with the slightest amount of air movement. *by E***F on April 15, 2025* Excellent duct damper.

Install straight forward with arrows as directed for flow / operation of ducting flapper. Installed with very short sheet metal screws to prevent lint build up inside ducting. Can be installed with hose clamps if non city code requirement. ### ⭐⭐⭐⭐⭐ I am thrilled! *by A***I on February 8, 2024* I had two vents that were banging very loudly when it was a windy day. My vent for the hood over my stove was 5" and the other vent (from my dryer) was 4". So, I am glad I purchased both sizes. Don't assume you know the size. Anyways, these work GREAT. I do have a plastic cover that hides them from the outside, but all of that terrible banging has stopped. Occasionally, I will hear them open and close, but they are much quieter due to the rubber seal inside. Great product and builders really need to install these instead of those loud clanging plastic ones!
