Similar joints are availble from Flaming River. The FR ones are nickel plated; http://www.flamingriver.com/index.cf...cat/cat115.htm , which are way less prone to rusting than the plain steel ones from Borgeson. What John has here appear to be the stainless Borgesons (?) which would be almost corrosion proof. Both are good quality products, just different approachs/materials/finishes for more options to we users.

Likin' the progress John.
