Design and detail flashing and weep holes in exterior veneer to divert water to the exterior. Weepholes shall be at least 3/16 in. (5 mm) in diameter and spaced less than 33 in. (838 mm) on center.

Manufacturer's Comment: To increase the amount of air flow in cavity walls we recommend a cell vent/ Wire-Bond 3601 or louvered weep (Wire-Bond 3602) every 24".

Anchor Requirements

Corrugated sheet metal anchors - Corrugated sheet metal anchors shall be at least 7/8 in. (22 mm) wide, have a base metal thickness of at least 0.03 in.
