In some places, businesses use a pass-thru, to pass cash or goods back and forth; this could be at a bank or a liquor store. The highest standard of pass-thru use bullet proof glass, although this material is far too expensive to be used as a protective measure by those business where it might be most effective. Therein plastic is used in place of bullet proof glass. They are either made by a manufacturer or by the shop owner. This Pass-Thru was made by Rowland.
