Conventional doors proving to be a bit of a drama in NZ conditions, most insurance claims in housed systems are doors... either mounted by a loader or the wind These AG screen doors are specifically designed for Cow houses. Up to 6 meters wide and 6 meters high and placed on the outside of the building so access and opening is ease.... Also great as a fire escape and a knife at the door would allow you to cut your way out This could save you having to have a fire report and extensive cost in providing extra exit doors
