Series 5600 Inside Glazed Installation Instructions
Section IV: Perimeter Application
B.) First attach the vertical pressure plates and then the horizontal pressure plates
into position using #13 X 5/8” stainless steel hex washer head screws. Locate
screws at 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.
C.) 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.
D.) Seal all joints between the vertical and horizontal pressure plates with sealant
which will provide a water and airtight joint.
*Note: The glazier should always place a screw in the vertical
pressure plate directly opposite each horizontal. This is
necessary to create maximum control of pressure on the
mullion plugs, which provide the critical sealing function.
