Personnel (walk-in) doors can be installed at any location in the building . Wall girts below the
standard level of seven feet four inches will have to be cut out for the doorframe .
After deciding where the door is to be located and before the wall sheets are installed, attach the
doorframe to the foundation and the wall girt or girts . The doorframe can be bolted to the girt and
foundation where and however desired . The base angle will have to be cut out in the door opening .
Make sure the doorframe is square so the door will fit and open and close properly .
After the doorframe is installed and squared, the door can be placed on the hinges, the doorknob
and locks installed, and the threshold plate placed at the bottom of the door opening .
