Schools, universities, government agencies, libraries always have assigned sections for wall glass display showcases. They may use them to display trophies, memorabilia, documents, artwork or scientific instrumentation to name a few. Institutions will use large size wall display cases since they have many items to showcase. Most of the wall cases you will see in institutions have multiple adjustable shelves, are lockable and made of tempered glass. They are all pre assembled and dust resistant. A conventional wall showcase ought to be low maintenance since they are installed in a semi public environment with a good amount of traffic. Newer wall display showcases models have central dividers built into them that allows the creation of multiple compartments. Institutions need showcases all the time and consequently manufacturers have to come with new wall cases concepts all the time.
