Here is a little more information on the Walker Dynomax 41973. It is a 3" inner diameter to 2.5" inner diameter Reducing Bushing that is 6" long. Using a micrometer to measure, it was made with 1/16" ~ 1.79mm thick Aluminized Steel. This is a well constructed item that is fairly well deburred and will suit my need nicely. Item shipped in a single walled cardboard box with Polyair packing material and arrived in good condition. Information like this would probably help these units sell better.K. Stevens

Good price, good quality. Not a fan of the notches; just more to weld up.

Both ends were not perfectly circle so it could not fit on the pipes on either end but I have an expander so it was a non-issue to me. I do really like how it’s not just one single reduction in size but rather steps down twice to get to the 2.5 inches.
