Rated 5.0 out of 5.0 by Duke 3 inch round duct cap
Dimensions were correct, galvanizing was evenly applied, item was strongly constructed. Good for projects requiring closure of a 3 inch pipe, tube, or duct.

Rated 5.0 out of 5.0 by Jeepinguy Good quality
I used this 3 inch duct cap attached to a 3 inch semi rigid flex hose for a generator exhaust I made. I cut a 1 inch hole in the cap and inserted industrial grade magnets in the cap to keep the cap tight to the muffler. It worked great.

Just what I needed for my project. Dimensions were critical and as specified.

Rated 5.0 out of 5.0 by Bobby Just what I needed
I used the 3" cap in an exhaust system on a portable generator. I needed something to convert from a
1" muffler to a 3" outlet in my weather proof enclosure. I drilled a 1" hole in the cap and secured it with a clamp and used a 3" x 4" reducer to get to my 4" exhaust outlet. The cap was just the thing that I needed.

Rated 4.0 out of 5.0 by John Deeper than pictured
Item is constructed of sturdy galvanized steel and is almost 2" deep. It did work perfectly for my generator exhaust kit to help attach to the muffler.

Rated 1.0 out of 5.0 by hampster very poorly built and poor welding
This product was poorly constructed as the welding work was rather unprofessional. It appeared to be slightly larger than the specifications.
