End Treatments: SKT™
NEW! SKT-SP Standard Post System – the same SKT already
in use all across America
- Enhanced upper and lower hinged Post #1
- Hinged W6 Post #2, no ground strut
- Cost savings for Post #3 and beyond:
- generic standard W6 steel guardrail posts
- standard W-Beam rail sections
- Simplified installation and maintenance
How the SKT™ Functions
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
New Soil Plate Option
The FHWA now allows the 4'-6'' long foundation tubes at posts 3
& 4 or posts 3 - 8 to be installed without the soil plates.
This design is optional and the contract plans must be followed.
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
- 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.
- Fits a wide range of applications:
- Wood or Steel Posts
- Test Level 2 and 3 Speed
Note: The SKT is available in a 2, 4, or 8 foundation
