Rockford Systems鈥� GermBlock shields provide a transparent barrier between people when they are face-to-face to prevent the spread of respiratory droplets that can carry the virus. Unlike flimsy plastic barriers that easily chip and break, GermBlock shields are constructed of heavy-duty clear 3/16鈥� polycarbonate and 16-gauge 304 stainless steel 戮鈥� framing with full penetration welds, so they won鈥檛 be damaged by everyday usage, accidents or vandalism. In addition, the stainless-steel frame allows the shields to be washed down and sterilized per the CDC鈥檚 recommendation for frequent cleaning.
