Free standing glass display towers are better fit with hinged doors. In as long as the glass door does not exceed twenty four inches the hinges will support the glass panel well.

Manufacturers are commonly using plunger locks to keep the two doors tightly closed. Plunger locks are easy to operate and can be used similarly on all the wall trophy showcases within the store. They are easy to install on the outer glass sliding doors and may be easily replaced. It takes only minutes to install any glass sliding door once you receive your shipment. Just lift it and place it on the tracks. Since the glass doors are typically the front side of a display showcase they should be kept clean at all times.
