6" Slip Base Assemblies


Slip Base Break Away Sign Pole Bases for Single Column Signs

Our Slip base joins two separate posts via connector aluminum base plates. This joint allows the pair to break apart at an intended juncture. A basic slip system is assembled as follows:

A lower post (with a slip base aluminum base plate on its top) is put into the ground

An upper post (with a slip base aluminum base plate at its base) is situated above

The two aluminum base plates are joined using carefully-torqued bolts

Breakaway points are generally located close to the ground level. When the upper post is impacted, the aluminum base plates slip and bolts sever (or pop out). This allows the above-ground piece to get knocked out of the way while the vehicle passes over its underground counterpart.
