Hi all,
Here's another option for anyone looking to put barriers up at your libraries.
Pennzoni Display Company in Sturgis has been great with us. They sell a wide variety of acrylic plexiglass products, including
sneeze guards. They also sell "drum booths" made of 6'x2' panels with hinges to allow you to have taller barriers if you need them.
The edges are rounded off, not square and sharp like a piece of plexiglass from the hardware store might be, and the hinges make it super easy to mix and match the different sizes of plexiglass to custom make a wall with pass-through openings of any arbitrary length. Depending on the shape you come up with, it might be perfectly free-standing and self-supporting, like a drum booth usually is. Or, you can use gaffer's tape, which is strong, easy to work with, and leaves no residue when gently pulled off. (Gaffer Power is a great brand. Some of the cheaper ones don't tear off the roll as easily and do leave residue sometimes.)
Pennzoni can do tax-exempt, but cannot do purchase orders. So pre-pay with a check or use a credit card. They were very responsive to email and phone inquiries, and even helped me load more than 50 sheets of plexiglass into my van when I went to pick it up. (We are close to Sturgis, they also ship via FedEx.)
Attached are some shots of how we used these pieces to create barriers at some of our service points. One word of caution: while assembling the 6' sections is possible for one person, it really works better—and much faster!—with two.
Be well!
