Wall glass display cases are functional and allow you to display a vast amount of merchandise on multi layers or shelves. They can vary much in width, height and depth and can fill the displaying requirements of many businesses. Wall cases are commonly manufactured with fully adjustable shelves and may have an optional lockable storage cabinet in their base. When very narrow in depth it is recommended that the wall display showcase be attached to the wall it is placed against. This can be done by drilling some holes inside the top canopy and then screwing it to the studs in the wall. Wall display showcases may be manufactured with thin cabinets at the base and top leaving a large glass display area in the middle. Alternatively wall glass showcase may have a tall base cabinet with storage and a four to six inches tall top canopy. Many looks are available. In the case of very wide wall cases center dividers will be installed for structural integrity. Wall glass display cases are by far the most popular displays.
