[Rhodes22-list] Spreaders

[recorderguy2001 at yahoo.com]

Hi all,
   I've decided to replace my mismatched spreader bars.  I've tried contacting Dwyer, but they aren't in a rush to answer my message, so I thought I'd look elsewhere.  My problem is I don't know exactly what type of tube I'm looking for.  I'm guessing these are stainless steel tubes, is that correct.  Would 304 16 gauge be sufficient?  Or should I be looking at aluminium?  Any thoughts?

Thanks,
    Peter
