J-J Hooks is the most efficient, secure barrier system available. Proprietary J-Hook connection stands apart from all other systems. Over one million linear feet installed. Faster setting times save money during placement and removal. Self-aligning connection automatically "hooks" into place. Smaller crews, only a loader operator and ground man. No pins, bolts, or loose hardware.
VISI-BARRIER™ polymer concrete barrier panels are used for medians, tunnels, bridge parapets and bridge rails. A retro-reflective safety stripe gives high visibility in all weather conditions. The bright, white surface resists salts, chlorides and corrosion. Visi-Barrier™ can be custom designed to fit a wide variety of sites.
