sleeve. The sleeve cannot support the load of bricks/blocks.
For existing construction, wall opening must be created, the proper dimensions are necessary to avoid use of fillers
or additional framing .The sleeve is modular in height and width (refer to Fig 5& Chart 2).
Height:
Fits 2 courses concrete block
Fits 6 courses standard brick
Fits 5 courses jumbo brick
Width:
Fit approximately 3 stud spaces.
