H&B 343 - Louvered Weep Holes - 2-1/4" - Box of 200
The H&B 343 Louvered Weep Hole is designed to improve moisture drainage and ventilation in brick veneer cavity walls. Made from injection-molded flexible PVC, it features a louvered face that directs water out of the cavity while helping prevent the reverse flow of water and debris into the wall system.
This weep vent promotes cavity air movement to aid pressure equalization, reducing suction forces that can lead to water penetration. The integrated rectangular closure strip prevents mortar droppings from clogging the drainage path, helping ensure long-term performance.
Each unit includes compressible flanges to fit joint widths from 1/2 in. to 3/4 in., making it a versatile solution for residential, commercial, or institutional masonry applications. The 343 Louvered Weep Hole is ideal for any project where moisture control and drainage in the wall cavity are a priority.
