The CRL Sliding Deal Tray and Pass-Thru Bin handles two jobs using one unit. The sliding lid has a built-in deal tray for transferring cash and small items by sliding the lid forward and back. Bulk items can be passed through the larger bin cavity below (bin does not slide). The 5" (127 mm) deep cross member on the top of the unit allows for through-wall installations. The unit can also be mounted on a counter top with the window notched around it. An overhang or awning is recommended if used in an exterior application. Openings are 14" (356 mm) wide x 6" (152 mm) deep when not covered by sliding tray.
