U-Head Jack A Scaffolding U-Head Jack is a specialized scaffolding component designed to provide support and stability for beams and slabs. This adjustable device features a U-shaped head at the top, which is specifically designed to cradle timber beams or scaffolding boards. The U-Head Jack is typically mounted on top of a vertical scaffolding post, and its height can be adjusted to ensure a level support structure for the construction of floors, ceilings, or other horizontal surfaces. Made primarily from high-strength steel, the U-Head Jack is durable and capable of supporting significant loads, making it an essential part of ensuring the safety and integrity of construction and renovation projects. Its design allows for easy adjustment and a secure fit, facilitating efficient and safe building processes.
