As you can see, the rebar cage has been suspended inside the form. The concrete blocks were used to hold the base section up from the bottom of the hole. Per Trylon specs, 3.5 feet of the 4 foot long stub legs are to be inside the hole (6 inches to be showing above the concrete). Since the hole is 6 feet deep, we needed to keep the legs 2.5 feet from the bottom of the hole). To keep the blocks steady, we pushed some cable-spool rods next to each stack of blocks. It wasn't necessary. With the weight of the stub legs and the bottom section, it didn't budge, not even with the concrete flowing.
