For vertical weep holes, what is the maximum height for the weep holes? I was thinking 2 1/2 " from BIA??

From BOA Technical Note 11B Part 3: (from here: https://www.gobrick.com/docs/default-source/read-research-documents/technicalnotes/11b-guide-specifications-for-brick-masonry-part-3.pdf?sfvrsn=0 )
E. Weep Holes:
1. Provide weep holes in head joints in first course immediately above all flashing by: (a)
Leaving head joint free and clean of mortar
(a) Placing and leaving sash cord in joint.
2. Maximum spacing: 24 in. (610 mm) o.c.
3. Keep weep holes and area above flashing free of mortar droppings.

When in that 'soldier' orientation, the 'head joint' is the full height of the soldier brick.
