One of the most common enemies of SCREEN doors are pets. Dogs and cats and sometimes little children are well known for keeping the rescreening companies in business.
As many folks know, there are products on the market frequently called “Pet Guards,” usually constructed of aluminum for those who want to maximize the doors ability to ventilate.
But another, perhaps more durable option is to keep the screen out of reach by having the screen-door made with panels in the lower regions.
