[R-390] R390A shipping boxes

[Steve Toth]

The box I purchsed through Dan (Hank) Arney measures 24x24x16.  It has an ECT (edge crush test) rating of 500lbs (71ECT).  It is rated to hold 140 - 160 lbs of equipment.  IT appears that size is a custom order size.

Kubox has a 22x22x16 size "square box" that is just right for a little north of $90

After doing some extended searching on the web and looking at what is available the only double walled 500 lb / 71ECT size corrugated cardboard box I could find that would seem to work is 24x24x24.  Uline has them for ~$23.50 each but you have to purchase 10 at a whack.
The most common heavy duty double wall boxes available are 48ECT - rating of 275 lbs edge crush with a load limit of 100 lbs.
I pack my radios using the one inch thick hard foam board from Home Depot on all four sides, top and bottom after I plastic wrap them to prevent scuffing.  

Assuming I remove the power supplies and ship those separately, double box the radios and use the hard foam board, I'm thinking the 48 ECT boxes would work as the radios will weigh about 70lbs and the stiffness of the hard foam board would increase the edge crush rating of the box.
I for one would be interested in hearing details from the gentleman who is using hard foam and double walled boxes from Home Depot.
