Rainstopper isn’t just an off-the-shelf manufacturer. We’ve spent more than 50 years solving field problems with a full in-house fabrication shop, multiple U.S. patents, and the kind of hands-on experience that comes from working directly with municipalities and contractors.

Sometimes that means customizing one of our standard manhole inserts for an off-spec condition. Sometimes it means fabricating a durable stainless steel part when the original is unavailable, backordered, or no longer meeting the demands of the job.

After Hurricane Sandy, the New York MTA needed insert solutions for infrastructure challenges no standard product addressed: oversized openings, protruding locking lugs, and gas monitoring requirements. We didn’t have an off-the-shelf answer, so we engineered one. More than 250 units later, that work is still protecting infrastructure across all five boroughs.
