Adjustable tubing joints source???

[CoffeeRich]

Im looking for some small adjustable tubing joints. I have seen aluminum joints
that hold tubing with a set screw and have a nut and bolt that functions as the joint hinge. Anyone know where I can get some of these? I want to use them to construct a cubed frame. I have seen ones that are 1.5" and bigger, but none smaller. Im not even sure what they are called officially. Any help would be great.

Regards,
Rich

A picture would help.

Excuse the bad drawing but this is simular to what I am looking for. I have seen them used for safety rails, constructing desks, platforms, and scaffolding. Just looking for a clean way to fab a pipe cube without it looking
like a home depot jobby.

Stainless Steel and chromed "Rail Fittings" are used in the marine industry for spray shields/dodgers and awnings. Is that any help? 1/2, 5/8, 7/8. and 1 inch are typical - you can find 1 1/4. Some bits are made in plastic as well. Some of the manufacturers are; TaylorMade, Sea Fit, and a few others. Look for "rail fittings", and maybe Bimini, awning, etc to find a source. Boaties use 'em all the time. If you can find them thru a cheaper place than a marine dealer (might try an awning manufacturer or canvas outlet) - all the better! - Good luck, hope that helps - Jim
