• Remove existing door (may need to use rubber mallet to tap

upwards to remove)

• insert door onto the 2 hinge pins

NOTE: The top and bottom hinge pins can be moved in or out to adjust the amount of pressure on
the rope gasket when the door is closed. They also balance the gasket pressure between the left and
right sides. The top hinge pin can be moved left or right to adjust the centering of the rope gasket
on the door frame

The following 4 tests check the door alignment and pressure

held and cannot be pulled out. The
pressure must be such that the paper
will tear before it slides out.
Repeat at side left, side right, and
bottom center.

latched tight

Chalk the doorframe as

shown and then latch

the door tight to
