Smith-Midland manufactures, sells and rents thousands of feet of safety and security precast concrete barrier to meet your immediate needs. Installation crews and equipment are ready to start setting your barrier right away. More than one mile of barrier can be installed in 8 hours. We install highway safety barrier, security barrier, barrier with security fence, and J-J Hooks planters for all your temporary and permanent requirements. For more information visit www.jjhooks.com.
The J-J Hooks connection consists of two identical steel J-shaped hooks, which are cast into the barrier, creating a continuous steel connection. To attach the barrier ends, one barrier is lowered vertically next to an adjacent barrier. With minimal guidance, the self-aligning connection automatically “hooks” into place. Workers don’t need to endanger their hands by having them in between barriers during the connection process. The NCHRP 350 and MASH barrier designs connect directly to each other.
