Connection System

NCHRP-350, Test Level 3 Approved;
Jersey, F-shape, Constant Slope and Other Profiles

Self-aligning with no loose hardware

  • The only system available with no pins, bolts, or loose hardware that meets and exceeds the NCHRP-350, Test Level 3 requirements
  • Self-aligning – automatically “hooks” ® into place
  • Identical ends allow you to turn the barrier end-for-end
  • Fastest setting times and lowest installation costs
  • Vertical lift simplifies installation and removal
  • One barrier can be removed without disturbing adjacent barriers
  • Smaller installation crews, no loose hardware
  • Eliminates replacement costs for rusted nuts and lost bolts
  • Improved safety – no hands between barrier segments during placement
  • Tight radius ability

Fastest install/remove design has theft-proof connection

  • No loss of structural integrity or security breach due to lost or stolen hardware
  • Theft-proof connection means no missing or stolen pins and loose hardware
  • Self aligning means no need to “jostle” barrier when installing
    or removing pins that bind and slow setting/removal

An Economical Solution

  • Protecting utility plants, manufacturing facilities, office buildings, government installations, and city streets
  • Control vehicular and pedestrian traffic for major events, conferences, and concerts
  • Temporary security using JJ Hooks ® security fence to provide a higher level of security than any other temporary measure
  • Close off potentially dangerous areas such as foundations, propane tanks, excavated areas, damaged guardrails, and damaged bridges
  • Standard JJ Hooks ® barrier sections can be delivered from stock on short notice. Additionally, the sections can be modified to include a top-mounted security fence

Highways: NCHRP-350, Test Level 3, Crash Tested. Meets & exceeds requirements for Jersey, F-Shape, Constant Slope, and Other Profiles.

Meets NZTA (Transit NZ) requirements and is approved for all.

  • State and Federal transportation officials require positive connection barriers for increased safety. Approved in most states as well as many European and South American countries (See back page). (Also meets European Containment Level H2 for fixed barrier and Containment Levels T1, T2 and T3 for temporary safety barriers.)

  • 100% integral connections allow no loss of structural integrity due
    to bent or missing hardware. Provides a continuous positive shear
    connection throughout the barrier system.

Certified Crash Test Results: NCHRP-350 Report Test Designation 3

“SUMMARY OF FINDING: The JJ Hooks ® Jersey shape PCB system contained and redirected the vehicle. The vehicle did not penetrate, underride, nor override the installation. Maximum deflection of the barriers was 1.30 m. Fragments from the PCB were small and did not penetrate nor show potential for penetrating the occupant compartment, nor would they present undue hazard to others in the area. Maximum reduction of space was 7.9% in the instrument panel to the floor pan area, which was judged to not cause serious injuries. The vehicle remained upright during and after the collision event. The vehicle did not intrude into adjacent traffic lanes as it exited the test site … Exit angle as loss of contact with the PCB was 9.4 degrees which is 38% of the impact angle.”

The World's Most Widely Used Precast Concrete Barrier Connection System.

“We’ve been extremely pleased with JJ Hooks ®… The … barriers are not a male-female system like some of the
others … more versatility is built in which often allows less planning and less labor during traffic switches to ensure
the barrier is configured correctly … some of the other positive connection barrier systems bind up during placement
and removal often causing damage to the wall – the JJ Hooks ® system seldom does.”
Ryan Gorman, P.E., Sr. Project Manager

“We’re extremely happy with road barriers that have the JJ Hooks ® connection. .. They are much quicker and easier
to work with … 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 … Overall, we’re very impressed with the way this project is going with the use of JJ Hooks ® road barriers.”

“… we installed over 26,000 linear feet of temporary barrier wall in 20′ sections … in six shifts … removal was simplified by not having to pull pins or shake walls loose.”
