Abstract

A monolithic corner and/or adapter panel encapsulates one or more panels while maintaining structural integrity and maintain hygienic properties. The corner may securely receive one or more panels and provide flexibility to easily adjust the one or more panels. The corner and/or adapter panel may simplify installation and an ability to adjust connected panels without compromising safety, installation time, and sterility.

Claims (46)
