Popco’s suction cups range from 7/8-inches to 2.4-inches in diameter and are made of clear PVC. Their intended use is for supporting small signs in a point-of-purchase setting. Many of the Popco suction cups feature a mushroom-style cap which can support signs that have a keyhole cut, without any hook or sign-holding attachment. Other styles of Popco suction cups feature hooks, tacks, screws, adhesive tabs or even springs. This gives designers and retailers many options for displaying their signs. Popco produces their suction cups from proprietary tooling and manufactures the suction cups entirely in the U.S.A. This means that lead times are short, prices are competitive and, when you buy from Popco, you are supporting an American small business.
