Accessories

This robust Expanding Spigot Pin is a heavy-duty connector designed for achieving high-integrity, end-to-end extensions of scaffold tubes and modular frames. Unlike basic joint pins, this type features a central locking bolt that, when tightened, expands the split sleeve within the tube walls, creating a powerful, friction-based lock. This mechanism ensures maximum vertical load transfer and structural rigidity, making this zinc-plated component essential for safely and securely stacking scaffolding lifts.
