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
Slip Base Assemblies "break away" on impact, therefore reducing damage to the vehicle and its occupants. It's easy to install into the anchor; simply insert the bottom half of the slip base down into the anchor and secure with shoulder bolts. Then, insert the sign post into the top half receiver of the slip base and secure with shoulder bolts.
Upon impact, the top half of the slip base separates from the bottom half and in most instances the post sustains little or no damage. The slip base assembly can be used over and over again reducing waste and costs
