OVERVIEW

Product Overview

The Adjustable Base Jack is installed at the bottom of a ringlock scaffolding or shoring system to provide vertical height adjustment and transfer loads from the scaffold structure to the supporting base or foundation.

The threaded screw stem allows the bottom elevation of the scaffold to be adjusted according to site conditions, helping compensate for level differences during installation. Both 48 Series and 60 Series configurations are available, with a hot-dip galvanized finish for corrosion protection.
