Bi-Parting Transaction Window

This 42″W x 36″ manual transaction window with bi-parting, self-closing sliders is a smaller version of the BPSC-4836 in that the width has been narrowed to 42”. The height remains the same so that we can still offer a generous service opening of 14” (w) x 28 1/2” (h). This transaction window is made for businesses that have much smaller work areas to contend with and allow the business versatility of not having to cut a larger hole to use a standard 48” wide window. This pass-thru window also has a nice inside counter space for staging product. BPSC-4236: Unit Size: 42″W x 36″H
