The Kleen Break system is available, depending on the application, in Ground Mount and Surface Mount Assemblies. The Kleen Break system provides flush mounting so that after an impact, the bottom portion will remain flush with the surface to prevent tripping hazard(s) to pedestrians. When properly installed, the Kleen Break assembly supports the sign and post at 100% of the strength of the post for windloading, yet breaks away per NCHRP 350 criteria when impacted.

  • Allows for 360° indexing for proper sign orientation after anchoring half is permanently set
  • All components are reusable with the exception of the shear bolt, which must be replaced after each impact
  • Reuse of rubber bushing and locking wedge is determined by their condition after impact
  • Accepts 1 3/4″ and 2″ square posts
