Florida DOT approves J-J Hooks MASH-Tested Safety Barriers

Two J-J Hooks MASH TL3 precast concrete temporary barrier designs (free-standing & restrained) have been approved by the Florida Department of Transportation, a major milestone. This brings the current total to 17/32 states respectively approving its use, with additional approvals anticipated in the near future. J-J Hooks has played a leadership role in product innovation for safety in the highway construction industry since 1990.

J-J Hooks now provides State DOTs a full suite of free-standing and restrained (bolted or pinned) MASH (Manual for Assessing Safety Hardware) TL3-tested designs. Their availability in the marketplace occurred nearly two years ahead of the “sunset” date requirement contained in the January 7, 2016 AASHTO/FHWA Joint Implementation Agreement for MASH. AASHTO's MASH document presents uniform federal guidelines for crash-testing permanent and temporary highway safety hardware and recommends evaluation criteria to assess test results.

Currently, more than 14,000,000 linear feet of J-J Hooks temporary barrier have been produced and installed worldwide. All J-J Hooks barrier designs utilize the same J-Hook connection system which provides the industry’s fastest installation and removal capability, has integral self-aligning connection guides, and requires no loose hardware.
