When a scaffolding system is used to support beams or other structural members, the top support needs to be both adjustable and stable. A U Head Screw Jack is commonly installed at the top of a scaffold to provide this support. Its height can be adjusted according to the actual working level, making it practical for different construction conditions.
Adjustable Support for Different Scaffolding Systems
A typical U head jack consists of a screw bar, U head plate, and nut. The screw mechanism allows the height to be adjusted during installation, while the U-shaped plate holds the beam or structural member in position. For heavier loads, a welded triangular brace can be added to the head plate for extra strength.
The Adjustable U Head is available in both solid and hollow designs. A Hollow Screw Jack offers a lighter option for projects where weight and handling are important, while solid screw jacks can be selected for applications requiring greater load capacity.


Suitable for Modular Scaffolding
U Head Scaffolding accessories are widely used with ringlock, cuplock, and kwikstage scaffolding systems. They can serve as top or bottom supports and are commonly found in building construction, bridge projects, and other structural works.
The jacks can be manufactured from #20 or Q235 steel and supplied with painted, electro-galvanized, or hot-dip galvanized surfaces. Wooden pallets or steel pallets are available for packing and transportation.
