(4) points of internal contact around perimeter of BSD and Front Section. These stop the door travel when tightening hardware to prevent excess compression of rope gasket. Therefore, continued tightening of hardware will only bend the hinge pockets. Use a hand wrench to tighten the hardware. Use an alternating tightening method from right side to left side cap screws to secure door until sealed without applying
excessive torque. Never tighten hardware on either side 100% without using the alternating tightening method.
Failure to follow the prescribed procedure could cause thread damage, a crack in the casting or a leak in the door seal.
