Clam Shell Vents
Is there a vent with a hose connection diameter of 4"?
I'm not sure. My application required a 3" hose connection AND we plan to use 3" PVC white pipe for a better install. While you may not want to do this -- one option might be for you to go with a 3" to 4" PVC reducer/expander that would get to a 4" dimension. As is known, this would reduce the airflow to only what the 3" vent and the 3" to 4" connector can accommodate AND not true 4" venting. Merely a thought.
These vents use a 3" hose
What are the dimensions? Height? Width? Thickness?
The widest point is 5-13/16" and the highest point is 1-15/16"
What is the diameter of the hose connection?
The size is 3" for the hose connection.
I Would Buy This Product Again
This product was exactly as described on the JD website. It was a breeze to install and significantly higher quality that the plastic component it replaced. I would buy this again and recommend others to purchase it too.
Very Good Replacement for a Plastic Part
This part was a replacement for a plastic exhaust vent that is no longer in production. It is a very high quality item that fit exactly as described.I would purchase these again.
In the process of restoring a 1986 Supra Inboard Ski Boat and wanted to replace the front ventilation. Wanted to find a modern (and better looking) clam-shell type vent in stainless steel. This VENT (bought 2) fit the bill. I plan to use hard-pipe (PVC) to install them -- not the flimsy flexible hose that is prone to getting damaged. BOTTOM-LINE -- very pleased with the Vent and Jamestown Distributor's pricing, Customer Service and prompt delivery.
Installed 2 of these, they're excellent!
I've installed two of these on our trawler, to function as the venting for two of the Vetus 12V fans I installed. They were easy to install, well made and work extremely well!
