This is a shelter door that typically would be used upon our Underground SafeDen shelter with our 311 locking system. By building the hatch as an independent unit, it can be placed into differing shelter construction projects. This hatch type door can be built to your needed size.  A typical door will be 30”X30”.  This door can also be built to the size of our typical Underground SafeDen door which is 30"X60". Our FEMA 320 hatch door can be built with a weld stud design for the anchorage to take place during a shelter pour or it can be built so that anchorage is secured via anchor bolts on the face of the door. This type of door is used when you are pouring a concrete floor/roof for a shelter beneath your home, shop, etc. It has also been used upon prepared 'fall out shelters' in your secure location.
