I travel extensively for long-term assignments for work. Where there is 220v, my B&O gear goes along with me. (BL5's, 3's, BV7-40 and BC2). I found that the boxes dont last too long if used more than a couple of times so I had flight cases made for all my gear:-
The BL5 cases (shown), is a 4-sided box with a snap-on and lock 2-sided lid. This enables me to lift the BL5 into the box. I have found that the polystryene inserts that come with the manufactures packaging is the best. It locks everything down tight and can be locked for security purposes.
The cost of that box was approx GBP200 but considering what they are carrying and how often, it's well worth it for me.
The internal dimensions of the box are 745mm x 540mm x 1045mm.
