We were contacted by a customer who was in the process of opening a new warehouse in Richmond. They were looking to update their office and and help keep some heat in. What they asked for was a large single piece of glass with a pass through in the bottom for delivery drivers to hand their papers through. That is exactly what they got! We measured to fit and returned approximately 1 week later to install. The custom cut 6mm Tempered glass with pass through is held in place custom wood trim.
