Evaluation & Recommendation
UB33G U-bolts are perfect for larger trailers or any application involving a 75mm square drawbar. Their 100mm arms and 45mm threaded section provide the necessary holding power for structural components, winch brackets, and more.
If your build involves heavy towing, drawbar upgrades, or box-section frame modifications, this model is well suited. For different dimensions or mounting needs, feel free to contact our team.
Installation Tip: Ensure that the U-bolt is seated flat across the mounting surface, and tighten both nuts evenly to distribute load. Use spring washers or nylocs for added security.
