TKO Doors says the Flyweight screen door keeps out birds, flies, moths, mosquitoes, gnats, wasps and other pests, plus dust and debris. The door is held securely on each side by an extruded aluminum guide track and when rolled up is completely out of the way. The track is available with inside-the-door, stand-off, in-jamb or exterior wall face mounting. It is available in four power option models, including two motorized versions, a spring-tube model and a chain-hoist version. The doors are equipped with horizontal stiffeners and horizontal safety stripes that allow workers to see if the screen is down.
