Streamline Transfers 
Terra's convenient tranfer window is ideal for pharmacies, offices or labs where users need a fast, easy way to pass materials and documents from one room through to another. Install this pass-through window portal in areas that do not require strict between-room environmental control, such as differential pressure, in order to streamline workflow and communication. 
 
Doors 
Terra’s pass-through swing door can be pulled/pushed open from either side. A door stop on the shelf side can be engaged to prevent opening the door toward the shelf, pushing items to the floor. When opened more than halfway, the swing door will stay open until manually pushed closed. The door can also be latched closed by turning the handle into a notch build into the side frame. Pressure-rated versions of the swing door maintain pressure differentials up to 0.5" WC, making them suitable for use between rooms with cascading room pressures. 
 
The pass-through sliding door can also be opened from either side. It is mounted on spring-loaded rollers that smoothly glide in a polypropylene track. Springs keep the rollers engaged with the track, ensuring fluid door movement without derailment. 
 
Half-inch-thick doors, supported by strong chrome-plated hardware, are made of either white, opaque polypropylene or clear tempered glass, allowing privacy or visibility into the room beyond. 
 
 
Frame and Shelves 
The adjustable sturdy window frame is designed to accommodate standard walls up to 4" thick; frame can be customized to fit non-standard thicknesses. One side of the Pass-Through Convenience Window features a reinforced 12" D shelf where users can set samples, supplies or paperwork until a user on the opposing side is ready to receive them. It's also a handy writing surface. 
 
The swing-door model is available with 304 stainless steel shelf and frame, while the sliding-door model comes with a white polypropylene frame, door tracks and lipped shelf, a feature that prevents small parts from rolling off onto the floor. Choose either glass or white polypropylene door for either door design; 0.50"-thick material for swing doors, and 0.75"-thick material for sliding doors. 
 
Floor Models 
Pass-Through Convenience Windows can also be installed in larger openings along the floor, using the swing-door option only, with either stainless steel or polypropylene frame (no shelf). The opening is framed on all four sides to create stability. 
 
Fire-Rated Convenience Door 
Terra’s self-closing door features a 2.56" (65 mm) -thick, uninsulated 304 stainless steel access panel (door) with a pull handle. Its one-inch exposed flange can be mounted on any typical wall material. These modules bear a UL- listed “B" label for 1.5 hours in walls (maximum temperature rise to 250°F (121°C) in 30 minutes). 
 
Doors open from one side only, and come with stainless steel frame and shelf. Contact Terra to discuss your needs: phone, email, or on-line chat.
