To ensure that the unit will assemble correctly, verify that the structural glazed mullion
and filler are fabricated opposite of each other. Apply butyl type sealant to the end of all
horizontal members that come into contact with the structural glazed mullion. Install
anchors into the head. Before assembly, apply wax lubricant to all STC8 fasteners.
Fasten the structural glazed mullion to all horizontal members. Fasten the opposite
vertical mullion, jamb, etc. to the other end of the horizontals. Make sure that butyl type
sealant has been applied to the other ends of the horizontal members. Ensure that
anchor straps have been installed if required. Wipe off all excess sealant.
