Assemble the parts and hang S-hooks Assemble the pipe, elbows, nipples and floor flanges, then screw through the flanges to a horizontal 2x4 set at shoulder height on a garage or shop wall. Attach your S-hooks. If yours don't fit, clamp the hooks in a vise and bend open one end just enough to fit on the pipe after assembly. Now snap Cable Clamps on all your coils and hang them from the S-hooks.
