I hear ya. I have been hit in the head twice by a 48" Bessey and nearly knocked me out both times! Wasn't a problem with my rack though, more of a problem with me being in a rush.

Before I sold all my besseys and jorgys, the heads were all hanging downward.

Looking at the long clamps, if the heads are not touching the wall, then the cantilever weight of the clamp head is trying to rotate the top of the bar out of the rack.
If that is the rack that is dropping clamps, I would suggest adding a thin strip of wood to the wall behind the lower end of the clamps. The strip should be just long enough that the clamp bar is not touching the back of the lower slots. That might not completely solve the problem, but it should significantly reduce the lever arm at the fulcrum (by changing the fulcrum) and make drops less frequent.

Any further help and suggestions would be appreciated.

Make small wedge shapes to add on top bearing surface to tilt things back a smidge.

My bar clamp rack is pretty simple.

One other suggestion that I don't think has been made it to epoxy a couple of rare earth magnets in each of the slots that holds the head. Might help just a little. When you decide to rebuild them take a look at the ones Lee Valley offers. They are pretty cheap compared to making your own.

Ahhh that there is your problem not the racks.

You mean being the Army for 22 years or wearing a helmet?
BTW, everytime we made contact in Nam I would flip that darn thing off of my head. I was to small to maneuver with it on. It always hurt my neck from its weight.
Very funny Arlin!

This is what I did for my parallel clamps since they are above my crosscut bench. It is just some eye bolts, a scrap piece of conduit, and a pin to hold it in place.
