StormCloset® Tornado Shelter Door
Access to StormCloset® is through an architectural, steel door which may be placed in any wall of the tornado shelter to meet the customer's unique architectural requirements (see
Planning Template). Specially reinforced, welded 14 gauge doors have been successfully pressure and impact tested for inward and outward swings and are available in two sizes, 2'-8" wide or 3'-0" wide (meets handicap codes and ADA requirements). Steel doors and framing are prime painted, prepped for furnished hardware indicated below,and have a 3/4 inch clearance from floor. Door frames are factory-prepped for hardware and attachment to the StormCloset® frame.
Door Hardware
Door HardwareEach tornado door is furnished with three ball bearing, heavy duty, paint primed hinges with non-removable pins, Falcon mortise lever lock with deadbolt, strike plate, and two keys.

Protected Air Vents
Welded air vent ducts with steel protective covers are provided to assure ample breathing air and atmospheric pressure balancing.
Superior Anchoring System
StormCloset® is anchored to 4 inch thick, minimum, concrete floor slabs with threaded masonry anchors spaced at every 4 inches along each wall. In addition, 1/2 inch expansion anchors with plate washers are added at each shelter corner and at each side of the door. When exposed to 250 mph wind, no anchorage connector would be stressed more than 60% of its ultimate shear or pullout capacity. Minimum average resistance's of shelter anchoring devices are Horizontal: 1,695 pounds per linear foot of wall
Uplift: 2,385 pounds per linear foot of wall Based on allowable stresses of the anchorage connectors, the minimum total resistance's of the two basic models of StormCloset® are given in the table below:
