#343 Louvered Weep Hole
#343W - Wilko™ Weep Hole

  • Injection-molded flexible PVC (#343)/painted aluminum (#343W).
  • Configuration of louvers directs passage of water from cavity to outside of building, while preventing reverse passage of water.
  • Design permits air passage into cavity, thus aiding pressure equalization and reducing suction which can cause water penetration.
  • Rectangular closure strip prevents mortar droppings from clogging openings (#343).
  • Compressible flanges can accommodate joint widths of 1/2 in. – 3/4 in. (#343).
  • #343 available in gray only. #343W: Gray or white.

# QV – Quadro-Vent™

  • Quadro-Vent's honeycomb design allows passage of moisture from cavity to the building exterior while restricting ingress of insects and other debris.
  • Quadro-Vent allows passage of moisture up to its 2 1/2 in. height, important in the event of mortar droppings at bottom of cavity.
  • Polypropylene tested in conformance with ASTM D2240, D790B, D638 and D1238B.
  • Available in gray or white.
