Our take on the Foundation Vent / Animal Guard, 10 x 18 in., case of 10

A one-piece galvanized steel guard that mounts over a 10 x 18 in. foundation vent to keep birds, squirrels and rodents out. The 18 gauge expanded metal mesh has 3/8 in. openings, and the 1 in. frame has hemmed edges for stiffness. It is the simple fix for an open crawlspace vent, and it costs far less than a full vent replacement. Owners rate it well for fit and easy installation.
