RIB-BAK U-channel Sign Posts

RIB-BAK is the strongest U-channel post available. New billet steel has 25% more yield strength (80 – 100 KSI) than the rail steel used by our competitors. RIB-BAK withstands higher wind loads at crucial load bearing points, thus supporting heavier signs per post.

System features include:
  • Crashworthy to NCHRP 350 criteria.
  • U.S. new billet steel.
  • 80,000-Lb. minimum yield.
  • Fast easy installation with conventional tools.
  • Flush contact points for solid sign attachment.

10 foot post and taller can not be shipped UPS and must be shipped by freight line.
If residential or limited access delivery a charge between $75-100 would apply.
