Our verification notes

Certification is real and model-specific: the Side Deployed Flex-Wall 2510 is tested and approved to ANSI/FM 2510. Never write that the company is FM Approved - the approval belongs to the model. One important corporate note: ILC Dover sold its Flood Pro line to PS Industries in January 2023, so newer Flex-Wall and Flex-Gate products now sit with that manufacturer.
