Series 5600 Outside Glazed Installation Instructions
Section VII: Glazing Installation
Step #6 Apply Exterior Pressure Plates
A.) First attach the vertical pressure plates and then the horizontal pressure plates into
position using #13 X 5/8” S.S. Hex Washer Head screws. Locate screws 6” O.C. and
at a maximum of 3” from the ends of each pressure plate. Torque screws to 80
inch-pounds. When possible, work from the center outward on the horizontals and
from the sill upward on the verticals.
B.) In cold weather, first torque all pressure plate screws to 40 inch-pounds. Once all
four sides have been clamped down, torque all screws to 80 inch-pounds.
C.) Seal all joints between the vertical and horizontal pressure plates with sealant which
will provide a water and airtight joint.
Step #5 Install Side Blocks
A.) Install and position side “W” blocks in the jamb cavity as indicated.
Note: The glazier should always place a screw in the vertical pressure plate directly
opposite each horizontal. This is necessary to create a maximum control of pressure on
the mullion plugs, which provides the critical sealing function.
