The complete Storm Shelter weighs approximately 16,000 pounds (8 tons).

The door frame is 4” folded steel channel cast in place with cast-in place anchors for door stops. The door opens out and is 10 gauge (1/8”) steel convext for strength with 3/4” square tubular steel inner frame. Door stops are 3/16” thick steel and can be removed to open door inwards should it become blocked from the outside. The door has weather- stripping and a bottom sweep. If the weather- stripping and vents are maintained, the storm shelter is rodent proof.

Two four-inch vents are provided, one above the door and a back vent that extends to floor of shelter to create a natural circulation. Both vents have a removable grid and screen.

A 1/2” electric PVC is cast in the left side of the door with 1/2” NPT threads outside and 1/2” coupler inside. A 2” pump hose opening on right of door with 2” NPT threads outside and 2” coupler inside.
