I just ran 6 feet of 1/4 inch chain around the bar, attaching one end to the other so that half of the heavy chain is on the ground at the top of the lift. Then I just run the heavy chain inside the 1/4 inch chain. If making your own, it is much cheaper than Topper and it is not necessary to put in the triangle ring. Just running it through the light chain works just fine.
Hope this helps.
