1EA Roll-Up Door

The 1EA (1 inch Extruded Aluminum) door is suitable for smaller compartments or cabinets with minimal head room. The Slats are not sealed therefore the door is recommended for interior use or exterior use where there is limited exposure to the elements.


Applications include, but are not limited to, emergency vehicles, ambulances, maintenance vehicles, equipment trailers and vending trailers.
