Pretty straight forward. A piece of steel. Roughly the size required within mill parameters. Worked for my project.

I used this to create a bracket for a pole to raise and lower on a bat house i built. Works perfectly. Cut a small section off and was able to put a piece of electrical conduit(i forget diameter, but think it was 2") in it mounted on bolts. I painted it with regular spray paint to stop rust that was forming, but when it arrived it was clean and exactly what i ordered.

Bought a 2" x 2" x .065" piece to convert my roof mount bike racks to hitch mount. I was debating about getting the .065" or the .12" wall thickness. While the thicker tubing may be stronger, it's also double the weight. I am very glad I got the .065" wall thickness. It is very strong and can support my full body weight (200lb) jumping at the end of a 3ft piece mounted to the hitch without flexing at all - so it will easily support a couple 20lb bikes. It's a little dirty when it arrives so be careful if you're wearing nice clothes when handling it.

It's a 4 foot stick of square tube. Good price. Admittedly,I didn't take out a tape measure to verify exact length, and I didn't take micrometers to the tube wall thickness to verify, but it looks pretty solid. The end of the tube looks like it was cut from a plasma cutter: it wasn't the cleanest cut, but 2 minutes with a grinding wheel will smooth it out. For what I wanted out of it (building a tire carrier), it is perfect.

It is just a piece of metal, but when ordering a piece with a specific measurement, the piece better have those specifications. this piece of stock did. It fit nicely into the base I already had.Well done.
