J-J Hooks has a full suite of MASH-tested precast concrete temporary barrier. It is the temporary-barrier-of-choice among construction contractors due to its speed of installation/removal, no loose connection hardware, identical ends (can be turned end-to-end), cast-in self-aligning connection guide, and economical cost. Over 15,000,000 LF of J-J Hooks has been used on North American highways since its introduction in 1990.
