How the FLEAT Functions
The FLEAT 350 (FLared Energy Absorbing Terminal)
is an energy absorbing flared terminal. The flare is straight
and the offset is variable anywhere between 2'-6" and
4'-0". The FLEAT is 37'-6" long and has 7 breakaway
posts. NCHRP 350 APPROVED!
 |
The FLEAT combines the superior performance of the energy
absorbing tangent terminals with the advantage of flared
terminals in reducing nuisance impacts. During head-on
impacts, the FLEAT 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 FLEAT functions
like guardrail. The errant vehicle is safely redirected
back toward its original travel path. |
The FLEAT is the only NCHRP 350 / FHWA approved
Energy Absorbing Flared Terminal. The FHWA has recommended
that all non-energy absorbing flared terminals have
200 feet or more of barrier proper in advance of the
fixed object to allow for the vehicle to travel behind
and beyond the end of the terminal.
The FLEAT is the only NCHRP 350 / FHWA approved flared terminal with a steel post option.
The FLEAT is the only NCHRP 350 / FHWA approved flared terminal with a Test Level 2 option.

Benefits and Features
- The only component different from the SKT is the
impact head. This greatly reduces inventory requirements.
- The FLEAT is the only energy absorbing flared terminal
available. When impacted end-on, the kinetic energy
is able to be absorbed. With non-energy absorbing
terminals, the errant vehicle may travel nearly the
lenth of a football field behind and beyond the end
of the terminal.
- The FLEAT is the only Test Level 2 flared terminal
available.
- The FLEAT is the only flared terminal available
with a breakaway steel post option.
- Only 7 posts are required.
- The FLEAT has significantly fewer small components
than any other flared terminal. This substantially
reduces the installation and maintenance time.
- The flare is straight, not a parabolic curve. This
greatly simplifies the installation and improves the
performance for traffic face redirection impacts.
- The flare can be optimized to fit the site conditions.
The flare is variable anywhere between 2'-6"
and 4'-0". This may reduce the need for costly
site grading.
- The FLEAT is available from multiple distributors.
This means the end of sole source supply.
