Aloha Steve and Welcome aboard!
Just to say that it doesn't have to be a Cascade toerail but can be any brand if it suits your needs. I do like the toughness of the Cascade rail but you have so many more fabricators in your area that you might find something as good at a better price
than having something shipped from the Northwest.
Do you know about the great surplus metal places in San Leandro? If I can remember the name I'll get it to you.
