Hanging Iron / Gridwork

[derekleffew]

reggie98 and [user]TimMiller[/user] are both incorrect. The registered trademark product Speed-Rail® specifies only the fittings, not the pipe.

From: http://www.hollaender.com/files/1/Tech_Data/tech_faq.pdf

Q: What pipe materials can I use with Hollaender fittings?
A: Any metal pipe (including galvanized steel, stainless, black iron, aluminum, etc.) can be used with our slip-on fittings as long as it is sized
properly (see above). Plastic, FRP and thin wall sleaving should never be used unless a reinforcing dowel is also used inside the pipe.

Note that neither Speed-Rail® nor Kee Klamp® fittings are appropriate for overhead suspension applications.

Whether to use steel or aluminum pipe and what strength or gauge is one that requires careful consideration and consultation with one's rigging vendor.

now that i think about it, i am getting the two speed rail types mixed up in my head. There is speed rail in which uses set screws common for booth displays, but then there is the "speed rail" in which is used in the video industry, which is made up of pipe, with a sleeve that is slid into the fitting, then there are holes that line up, and a bolt is slid through the pipe, through the sleeve, and out the other side and secured with a nut. Many theatrical companies use this to install battons rather than pipe that is just threaded and joined together. The sleeve provides a much stronger union.
