4 in. x 2 ft. Aluminum Pipe

Certainly, I'm sure over time it will corrode and degrade, but I would expect that to take years.

Using my uncalibrated dial caliper... I measure the wall thickness at 0.012". Not sure what gauge that is.

For dust, I imagine it would hold a charge if not grounded at some point.

Hi Jared, sorry for the delay in our response. This product is actually safe for use in-wall. We will adjust the product description on the website accordingly. The difference between the 2 products is due to the regional supplying manufacturer. If you have further questions, please call our customer service toll free at 1-800-387-2578.

This is the only length available in the Everbilt brand.

Yes they do it’s approx 6.00 and change. Has piece that goes down through floor, wall, or ceiling that is to be secured and then the connector piece that kind of screws over the simi rigid duct and then it will snap into place inside the first piece that was secured. Absolutely makes it much easier to open up and clean and then connect it back not having to use the tape etc. in the store it’s right by all the aluminum duct supply and washing machine connection hoses.

That product may be available in another department, This item P4E20HD is a lighter gauge and will not pass code for in wall use.

No, this is not ANIS certified.

In my case, the pipes and fittings all slipped together and then I used heat rated silver tape to nake the pieces air tight.

The maximum heat rating on this pipe is 435 degrees F.
