Here are all of the parts that go into the front leg laying as they would go together.

From top left again, the broom clip (No Longer Used, Failed), the copper pipe cap, the 1 inch length of copper pipe the street elbow, with the conduit strap setting over it. And finally the 1/2 inch conduit.

Actually the name 1/2 conduit is quite an oxymoron. This stuff measures 5/8 inch on the inside and just under 3/4 inch, actually .700 inches, on the outside.

Where they get the 1/2 from I don't know. But, that makes about as much sense as the 1/2 copper street elbows that are 5/8 on their OD, such that they will fit into the conduit.
