Chase EconoMax Strip Doors are easy to install, maintain and if necessary repair or replace. They are very versatile and can adapt to a wide range of applications. Strip doors are commonly used as a secondary barrier when the primary barrier is left open for extended periods of time. A strip door permits unimpeded traffic flow of personnel, materials or equipment and maximizes productivity. When used in conjunction with cooler and freezer doors, strip doors are a cost-effective solution for saving energy, maintaining temperature and reducing condensation and icing problems inside coolers and freezers. Maintaining proper temperature inside coolers and freezers ensures that products are stored at specified temperatures, reducing spoilage and extending shelf life.
