Overview
The CAT® is a tangent, double-sided, re-directive/gating and energy absorbing attenuator/end terminal
available for use with various longitudinal highway barriers, in either unidirectional or bidirectional traffic
applications.
The CAT® consists of CAT® 10/12 gauge slotted guardrail, CAT® 10 gauge nose/side plates, channel strut,
CAT® anchor cable, CAT® treated wood posts/blocks, tube sleeves and various other required hardware
accessories.
The CAT® requires a 12’-6” [3.81 m] CAT® Tail; Single Sided or Double Sided.
The Single Sided CAT® Tail is used when the CAT® is connected to a single sided guardrail assembly.
•
Ensure this CAT® Tail is
not
used in a median application where the opposing traffic can impact the blunt
end of the CAT® Tail Guardrail, if it is inside the Clear Zone as defined by Roadside Design Guide (latest
edition).
•
See drawing SS220 when using 27 3/4” [705 mm] height downstream single sided guardrail assembly.
The Double Sided CAT® Tail is used when the CAT® is connected to a double sided guardrail assembly.
•
See drawing SS224 when using 27 3/4” [705 mm] height downstream double sided guardrail assembly.
•
See drawing SS695/SS696 when using 31” [787 mm] height downstream double sided guardrail assembly.
When used with rigid barriers, (i.e. concrete barrier, wall or bridge pier) a semi to rigid barrier
transition will be required (see state/specifying agency standards) as well as an appropriate CAT®
Tail.
