Nevermind my last post. I see you figured it out.
If I read the rules you posted, you are required to have a guard that protects on three sides, front, back and top. If you are going to make it yourself, then I think plexiglass is the way to go. It can be cut with a hand saw and bent by heating the area to be bent with a heat gun prior to bending. The link button does not seem to be enabled on this forum, so try googling bending plexi glass. Lots of vidios and websites pop up. You'll see it's not that complicated. As a suggestion, you will need a piece of plexiglass cut to this shape and dimensions:
The dotted lines are fold lines
A= 3/4 to one inch. This forms a lip on the upper side of the front opening to stiffen the top.
B= the hieght from the top of the condiment tray to the top of the sneeze guard plus 1 and 1/2 inches
C= the distance from the front of the condiment cooler to the edge of the top of the cart plus the thickness of the plexi glass
D= the hieght from the top of the condiment tray to the top of the sneeze guard
E= the distance from the left edge to the right edge of the condiment tray plus twice the thickness of the plexi glass
once you have cut out the sheet of plexiglass and made the bends you will need to seal the back corners with a NSF aproved adhesive calk or maybe epoxy. A stainless steel angle bracket pop riveted to each end of the condiment tray 1 and 1/2 inches down from the top of the condiment tray would hold the sneeze guard while allowing easy removal and cleaning.
The next question is:
If the sneeze guard had a door on the front of it, thereby protecting the contents from all four sides and top, would that do away with the need to provide separate storage for the serving utensils? Meaning, could the utensils be left sticking up through the lids on the condiment trays as long as the door was kept closed between uses?
I'm thinking a door that is hinged at the bottom, maybe with a catch that holds it in a horizontal position when open.
Edit: I see now why my link button doesn't work. I haven't been a member long enough.
