Thirty-five Departments of Transportation across North America have now approved J-J Hooks MASH barrier for use, with more anticipated in the near future.

The freestanding J-J Hooks MASH TL3 barrier now approved in Maryland will be produced by Easi-Set Licensed Producer Smith-Midland and available for rent through their Concrete Safety Systems division in the VA, DC, MD, DE, and northeast WV markets.
