Splice Fabrication
SP.1 Tape splice sleeve into upper section of vertical mullion. Weld or seal IW-122-01 caulk stop blocks to
both sides of splice joint to provide adequate sealant backer at face of mullion. SEE FIGURE 41.
SP.2 Drill (2) 9/32" dia. holes in lower mullion for splice attachment and one 7/32" hole
in lower mullion stop screw. SEE FIGURE 41. Install (1) FS-322 drill flex fastener into lower
mullion for splice stop. SEE FIGURE 42, page 36.
SP.3 When erecting wall, lower splice sleeve into lower mullion until it contacts stop screw.
Attach splice to mullion with (2) FS-8 fasteners. SEE FIGURE 42, page 36.
Add (2) FS-8 fasteners to upper mullion for hard splice conditions. SEE FIGURE 43, page 36.
SP.4 Apply bond breaker tape to face of splice on interior face of mullion. SEE FIGURE 42, page 36. .
SP.5 Seal splice joint along interior face of mullion back 1" on each side and seal exterior face of mullion
between ends of mullion and caulk blocks. SEE FIGURE 43, page 36. .
