Q:The attachment collar of the 843BL is 1-1/4" long and curves slightly inward at its end. At first glance, this does not look like much to attain a firm connection to. What is the best method to attach the duct to this collar?

    Q:I am using a 6" exhaust and venting my hood range through a corrugated tin wall with distance of 7" between ribs. The 843BL height is fine but I need something to fit this 7" range. Is there another model that would help with this?

      A:  Hi TonyB, Thank you for your question on model 843BL. There is no specific CDM level rated for this wall cap. This model is designed for any fan with a 6" duct size and the cfm's that come with this size duct should adequately open the damper.

            A:  Hi cone, Thank you for your question on the model 843BL wall cap. The collar on the cap is 6", so we would recommend you cut the hole slightly larger. Please contact Technical Support directly for more assistance at 888-336-6151.

              A:  Hole size should be about 6 1/4”.   The neck on the damper is sized to have a 6” pipe fit inside the neck of the damper.

                Solidly built, tough finish
                I haven't installed this yet. This is not a flimsy vent cap - it would take some serious force to dent. The screen is 1/4" mesh, also fairly sturdy, and mounted inside the external opening. The damper is spring-loaded, and closes against a foam strip so it shouldn't make much noise when closing. It's not clear what CFM is required to push open the damper, but it's not difficult to do so when I try blowing on it.

                    Great quality, I have installed many of these for kitchen exhaust hoods and vents. This is by far the most well put together with the internal spring-loaded door. It all but eliminates the noise made from the wind. Highly recommend.

                    This exterior range vent is made to withstand the elements throughout the year. A heavier guage metal is used, just like the ones of years past. Quality is what makes this product worth purchasing.

                    Solid construction. Spring closes slowly and quiet. Very pleased with this vent. Wish it had a female 6 in connection but was able to make it work with a coupler.

                    Doesn’t fit a 6 inch duct. Not the crimped side or the straight side. Doesn’t fit 6” flexible duct either.
