Robinson90 flexible uprigh and sign post

The optimal solution for the most critical sign placements on the road. 

Our Robinson90 model emerges as the top choice for pivotal transport infrastructure locations, such as traffic islands and roundabouts. Boasting a remarkable 90-degree flexibility, this post endures multiple drive-overs without incurring damage. Once installed, the Robinson90 sign post ensures the sign post remains intact, even after repeated impacts. Offered in both 60mm and 76mm diameters, and in two configurations: flexible sign post or flexible upright.

For sites where sign posts may face damage from slower impacts, Augustaflex upright is recommended.
