-

redirective crash cushion designed to 

shield permanent and portable barriers.  The TL

-

3 SLED End Treatment System consists of three water 

filled and one empty plastic modules to produce the desired energy attenuation characteristics to 

 

decelerate an impacting vehicle to meet TL

-

3 crashworthy requirements of Report NCHRP 350.  

 

Attached to the front empty module is the patented Containment Impact Sled (CIS) which collects the 
ruptured debris in front of the impacting vehicle..  

 

Additional Features:

-

2 array length is 18.9375 ft (5.77m) long.

 

 

Acceptable for Permanent and Portable installations.

 

 Attaches to various barrier shapes made of concrete, steel, or plastic.

 

 

All metal components are domestic sourced steel in accordance with Buy America requirements. 

 

 

Does not require any external steel for module assembly. 

 

 

Rotational molded plastic, modules are manufactured from specially formed material 

 

designed to be durable when handled and attenuate when impacted.
