CavClear® Weep Vents CavClear® Weep Vents are available in a variety of colors to blend with mortar. They are installed in vertical joints (open-head weeps) of brick masonry units at 24" (609.6 mm) spacing at the flashing level for moisture drainage and airflow. They prevent insects from entering and add visual continuity to open-joint weeps. The unique notch feature of CavClear® Weep Vents facilitates rapid drying. Open-head joint weeps increase ventilation over rope wicks. For better pressure equalization, install weep vents at both the top and bottom of the wall. Features and Benefits
