The Hinged Base Plate is designed for use with System 75 double tube mast systems. It provides a secure ground anchor point for the mast during deployment, allowing the mast to be walked to vertical from a hinged position.
The base plate is secured to the ground with pegs, and the double tube mast is slid into the plate before being raised to vertical by a 4-person team.
