Ralide Foundation Vents

Ralide foundation vents are rugged enough for decades of trouble-free service. Yet they cost less and retail for less than automatic vents. And that adds up to higher customer satisfaction, and higher profits for you.

A Foundation for Strength

Ralide's injection-molding manufacturing process, combined with our outstanding materials, produce vents with exceptionally consistent dimensions and strength. In fact, test results show that our foundation vents will support loads of 800 pounds.

Just as important, Ralide molded-composite vent casings are virtually impervious to even extreme temperatures and humidity levels. They will not warp under high heat or become brittle when exposed to extreme cold. And their vermin-proof screens will not rust or corrode.

Made from cost-effective, readily available materials, Ralide foundation vents offer homeowners decades of trouble-free operation.

Intelligent Design

Ralide's unique top flange design means no lintel is needed. Every vent is the exact height of one concrete block or three courses of brick with mortar. That means masons can hang it in place and complete the masonary work above it.










Easy to Use and Maintenance Free

Operating the Ralide foundation vent is as simple as sliding a clasp to open for summer and close for winter. Preparing a home for each season takes just moments.

Long-Term Economy

Ralide foundation vents cost about half as much as automatic vents. And they have no mechanical parts that can wear out or break, leading to premature replacement. So Ralide value and quality keep delivering, year after year.
