Product Overview
The Adjustable U-Head Jack is installed at the top of a ringlock scaffolding or shoring system to provide fine height adjustment and support for primary timber beams or steel members.
It consists of a threaded screw stem, adjusting nut and U-shaped head plate. By rotating the adjusting nut, the upper support level can be raised or lowered to match the required formwork elevation. Both 48 Series and 60 Series configurations are available.
