  • Removable post support system
    Patent number: 5848502
    Abstract: A system for mounting road signs and other posts which is simple to use, has few parts and is tamper resistant. The system also allows for the easy dismounting of the post for maintenance and changing of signs. The system uses a metal base driven into the ground, a non-square post with at least one flat side and a bifurcated wedge to lock the post into position in the base. This system also prevents rotation of the post due to winds or other forces.
