A U-Head Jack is a scaffolding accessory used to support and hold beams, formwork, or other structural members in place. It features a U-shaped head at the top, which provides a secure seat for timber or steel beams. The jack is usually adjustable, allowing for precise height control to ensure proper leveling and stability during construction. Made from heavy-duty steel, U-head jacks are strong, durable, and designed to carry heavy loads safely, making them essential in formwork and scaffolding systems.
