Hollow U Base Jack – Heavy-Duty Adjustable Support for Scaffolding

The Hollow U Base Jack plays a vital role in scaffolding. It provides strong, level, and height-adjustable support for beams, channels, and shuttering systems. Because it uses a durable hollow steel shaft along with an integrated U-Head, it maintains proper alignment and distributes load efficiently on construction sites. So even when the ground is uneven, the U Base Jack keeps the structure stable — whether you’re working with cuplock, ringlock, or conventional scaffolding.

What really makes this jack reliable is its drop-forged jack nut. It allows smooth adjustments, strong load handling, and consistent performance throughout the project. On top of that, the zinc-plated finish resists rust, making it a great choice for outdoor and long-duration applications.
