Questions about this item

How does the 1.25 in pipe size affect the fit on a real structure?

The fitting is made for pipe with a 1 5/8 in outer diameter and has a 1 3/4 in inside diameter, so it slides over the pipe and secures it to a flat surface.

What does the ASTM B179 535 listing cap in practice?

It confirms the aluminum alloy meets the ASTM B179 specification for corrosion-resistant structural pipe fittings.
