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!
New Hinged Steel Post Option available.

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.
NEW 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.
