Hanging Bar (Team Version)

[Retired Starman]

We are going to mount bars under our team built tower for one of Peachtree Region's Destination Einstein practice fields.

I purchased a 10 ft. length of 1 1/4 in thin wall conduit from Home Depot for less than $11.00. It has an outside diameter of 1.510 in. which is very close to the DOM tubing which should be 1.500 in.

DOM is smooth on the inside, hence it is used by FIRST in field elements that have to slide together. For our practice purposes, you don't need to go to the expense of using DOM since we are only interested in hanging on the outside. If you need something more precise than the conduit I mentioned above, you can go with ERW tubing. Identical to DOM on the outside, ERW has a small ridge inside where the welding was done.

For my money, I can live with 10 thousands of an inch oversize. There may be teams, however, who need the precision of the DOM. Hope they have a budget for it!
