EMT Elbow... Galvanized steel or Aluminum?

[Jonathan Cohn]

Hey guys, I've been searching for parts and I'm a little confused at the 90 degree elbow.

I found a product on mcmaster.com (8081K13): 90 degree 1" Galvanized steel Long Elbow

I'm unsure of the sizing and material.  Will steel be too heavy for the rig, and therefore aluminum is used?  Secondly, I'm not really sure what the standard dimensions are for these conduit pieces.  It gives a length of 9.25" from top to bottom, but no radius or circumference.

Any help is much appreciated.

Thanks!

The steel is what you want. You can try the aluminum and see if it works. I'm not sure that it will hold the weight of the sled.
