Now You think about what you just said. It takes 2 people to put an amp in it. It isn't the weight. It is to tight of a fit.
Lee we sent the larger aircraft parts in them. Never got them that were that tight. You figure a CSD is about 30,000.00 O/H. You don't want it bouncing around. But they weren't that tight. We flew parts to other stations. So we needed boxes like that.
