Kit nailed the thickness of the metal on the arm: 1/8" thickness, inside tube is 1" square and outside tube is 2.5" square (aluminum).
I talked to one of the mechanics (Mike D.) who helped us out and he said that, "there is 5/8" in each side of the box and we use Delrin rollers in each side. The chain is used to move the inside tube in and out."
So I hope that answers your question, FDA1029.
