[TheForge] Chain fall chain

Mon Sep 30 13:50:03 2002

Hey Mike,
The chain you tried is probably proof coil. It is the lowest strength and
generally the cheapest chain available. The link length is also longer.
I think most chain fall equipment uses "BBB" chain. It is higher strength
and the link length is shorter than proof coil links. This is done to insure
you use the proper strength chain.
You will probably have to order it from Mc Master Car or MSC supply.
