Silo Crib Railing is a nice addition to a silo to avoid those sudden drops to the bottom of the silo for your friends,
family or visitors to your Atlas site. The best ones that I have seen are in the pictures above. I believe that
1-1/2" Galvanized irrigation tubing was used for this project along with some1-1/2" DoughtyClamps and some
other misc pipe fittings to complete the railing. I found a link that has a bunch of stuff that could help on a project like this.

You can also aquire parts like this at some local iron yards or iron salvage yards.
You'll have to check your area for what is available.

This web site looks like it might have some stair railing ideas if you have railings missing going
down to the LCC.
