Portable Backstops came into their own when large sports arenas became popular. This is because the arena roofs are so high that it is nearly impossible to attach Ceiling Suspended Backstops to them. Portables provided the answer. Portables fold down and are rolled from the basketball arena to a storage area in a few minutes. This clears them from the area so that other sports surfaces and equipment can be quickly set up for other activities.
