Sliding Convenience window | Terra UniversalTerra Universal has developed an innovative solution to transferring materials between rooms when air lock or pressure control is not needed. Pass-Through Convenience Windows and Doors act as transfer and transaction portals, allowing users to exchange materials or documents easily through a swing or sliding door.

Doors are made of transparent ½”-thick tempered glass or white polypropylene to allow visibility or privacy between rooms, and open from either room side. A stainless-steel fire-rated door is also available. Models are available with a shelf that serves as a resting spot for materials or documents.  A flexible mounting system accommodates wall thicknesses from 3.5 – 4.5” thick; custom configurations are also available. Select among five sizes, ranging from 12”H x 12”W to 36”W x 48”H and come in wall- and floor-mount configurations.


The new Pass-Through Convenience Windows and Doors are ideal for pharmacies, doctors’ offices and labs in mind, to help streamline operations and increase efficiency.
