Because each unit is constructed of modular panels, you never have to worry about being trapped inside if the door is blocked from the storm debris. After installation, two wrenches are left inside the shelter to remove the bolts on any panel, allowing for multiple emergency exits.
The “Defender3” Model door on each Atlas Safe Room includes a spring-loaded vault-style handle that allows any user to easily engage the 3 bolt reinforced locking mechanism.
Overturning stability depends on the thickness (mass) of the concrete slab plus the distance the slab extends beyond the footprint of the shelter. Atlas engineering reveals that an 8” slab that extends 2’ beyond the shelter on each side is sufficient. Existing concrete slabs vary in thickness, steel reinforcement and build methods and therefore Atlas Safe Rooms certifies the structural integrity of the shelter alone.
