Kleen Break Assembly - Surface Mount (XKBSM42520-G)
Kleen Break Sign Post Coupler System
The Kleen Break System is a crash-tested frangible base ground-mounted sign assembly.
Xcessories Squared manufactures an NCHRP 350 crash-tested Kleen Break, a frangible device breakaway sign post base. The multi-directional breakaway Kleen Break is 360° indexable allowing exact orientation of the sign panel after the Kleen Break anchor is secured. It is capable of holding 100% of the strength capacity of the sign post.
Kleen Break Model 425 Concrete Mount, Wet Concrete, and Soil Installation
The most important aspect of any sign support product is the speed and ease of both installation and re-installation. The material needed for re-installation is also very important. The Kleen Break frangible base typically only requires a shear bolt set to be replaced, which is much less costly than replacing a frangible casting. The Kleen Break can hold a 2” square post.
