The brackets on both my 2A Bloodboxes (one now passed on to a good friend for rebuild - Gday Murray !) are made from aluminium. Dennis is dead righ about closing the left door with a water jerrycan in it. Eventuall you will wear a groove into the stretcher handle...

The one on the right I always assumed held a long plastic first aid box and/or water bottles.


hope this helps...

Cheers
