RIB-BAK U-channel Sign Support

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.
  • Available in seven sizes.
  • Powder coated or galvanized (bare available).
  • Fast easy installation with conventional tools.
  • Flush contact points for solid sign attachment.
