Double Jack Nut 48/60mm – Heavy-Duty Scaffolding Jack Component
The Double Jack Nut for 48mm and 60mm tubes is a heavy-duty scaffolding fitting used with adjustable U-jacks and base jacks. It allows precise height adjustment while safely carrying high structural loads. Because of its double-sided design, the nut grips firmly, stays stable under pressure, and performs reliably on long-duration construction sites.
As a result, it plays a key role in slab formwork, shuttering, staging, and load-bearing support systems.
