MASH Four-Cable System

The Valtir, formerly known as Trinity Highway Products CASS S3 M10 is our MASH approved cable system that assists in redirecting errant vehicles that would otherwise traverse the median of a roadway. Each CASS 3" S-Beam post employs a proprietary wave shaped slot, which works in tandem with strategically positioned cables to increase the system’s ability to restrain various types of vehicles. MASH testing on the CASS M10 has shown that this proprietary shape of the slots allows for lower deflections by minimizing the length of unsupported cables.
