How the SKT Functions

The SKT 350 (Sequential Kinking Terminal) is an energy absorbing tangent terminal. The SKT is 50'-0" long and has 8 breakaway posts. NCHRP 350 APPROVED!

During head-on impacts, the SKT head slides over the W-beam guardrail. The rail is sequentially kinked or bent as it moves through the head. The kinked guardrail exits the head safely and the vehicle is brought to a controlled stop. When impacted along the side within the length-of-need, the SKT functions like guardrail. The errant vehicle is safely redirected back toward its original travel path.


SOIL PLATE OPTION:
The FHWA now allows the 4'-6" long foundation tubes at posts 3 & 4 or posts 3 - 8 to be insalled without the soil plates. This design is optional and the contract plans must be followed. See FAQ #8 for additional information.


Benefits and Features
  • The only component different from the FLEAT is the impact head. This greatly reduces inventory requirements.
  • The forces required to push the impact head down the rail are lower than other tangent end terminals.
  • The impact head weighs less than 175 pounds. The high strength steel construction and lower impact forces results in a better performing design.
  • The impact head is significantly easier to remove from the rail compared to competitive systems.
  • The refined design over older technology improves the impact performance efficiency. The longer impact head and improved cable anchor bracket results in a better terminal.
  • The SKT is available from multiple distributors. This means the end of sole source supply.
  • The SKT is available in a 2, 4, or 8 foundation tube option.
  • Fits a wide range of applications:
    • Tangent
    • Wood or Steel Posts
    • Test Level 2 and 3 Speed
  • Also Available: SKT-LITE, shortened (37' 6" long) system with wood or steel posts
