b. Spacing Tie Bars. Space tie bars no more than 4 feet apart vertically. Fill the core of the block
with mortar or concrete and embed the right angle bend of the tie bar in the core (Figure 2-24).

2-24. Nonbearing Walls. To tie nonbearing walls to other walls, place metal-lath strips across the
joints in alternate courses between the two walls (Figure 2-25). If one wall is constructed first, build the
metal laths into the first wall. Later, tie the metal laths into the mortar joints of the second wall and
construct control joints where the two walls meet (Figure 2-26, page 2-26).
