H&B Quadro-Vent Rectangular Cell Vent Weephole - Box of 200
The H&B Quadro-Vent Rectangular Cell Vent is designed to enhance moisture drainage and air circulation in masonry cavity walls. Featuring a honeycomb internal structure, this vent allows water to exit the wall cavity while preventing insects and debris from entering. Its structure supports moisture passage up to 2-1/2 in. high, making it especially effective when mortar droppings have settled at the bottom of the cavity.
Manufactured from durable polypropylene, the Quadro-Vent is tested to ASTM standards (D2240, D790B, D638, D1238B) for performance and longevity. It is ideal for use in both the base and top of brick or stone veneer walls to promote consistent airflow and maintain cavity drainage integrity. Installation is simple and does not require any fasteners or adhesives.
Whether you're managing moisture at the foundation or equalizing air pressure near the top of the wall, this vent is a reliable, code-friendly solution for residential, commercial, or institutional masonry projects. Use it with flashing and weep systems for optimal performance.
