What is with the metal rods?
The metal rods are used because, for their strength, they are the least expensive option and they are easily obtained in most areas. The Multi-Frame and the Multi-Frame Kit each come with round rod ends for metal conduit (EMT). The round rod ends have micro teeth and can be used with ¾” or 1″ metal pipe. Use 1″ pipe for bigger projects, as it is more rigid. Two lengths of machine set screws are furnished so the rod ends are easy to move. *NOTE – small diameter PVC pipe is not an acceptable substitute for metal conduit. Here are two more tips; one for securing the big bolt into the Rod End (it is supposed to fit very, very tight) and a tip to use when you are ready to switch from the 48″ fiberglass rods to metal pipe for longer rods.
