• One J-J Hook® barrier can be removed without disturbing nearby barriers.
• J-J Hook® barriers provided the fastest installation/removal of any available barrier.

What are people saying about Kerkstra Precast's J-J Hook® median barriers?

“We’re extremely happy with Kerkstra Precast’s road barrier with J-J Hooks connections.  We wish we would have found these years ago, They are much quicker and easier to work with.  These barriers are safer as well; there is no reason for our guys to have their hands and fingers in the way since there is no loose hardware to put in place, which prevents many injuries.”
