ITEM SPECIFICS
The ARK UB5 Trailer U-Bolts are purpose-built for securing wide and flat trailer drawbars, especially those with a 130mm x 50mm profile. These U-bolts offer a generous 125mm internal width and a shorter 75mm arm length, making them a perfect fit for high-clearance requirements where long bolts are not necessary.
Product Features:
- Dimensions: 125mm internal width x 75mm arm length
- Thread Type: Supplied with compatible nuts for secure fastening
- Material: Galvanised steel – reliable performance in outdoor environments
- Compatibility: Suits trailer drawbars sized around 130mm x 50mm
Ideal Uses:
- Mounting trailer tongues or drawbars to chassis crossmembers
- Securing toolbox frames or winch post brackets
- Attaching couplings or accessories to flat, wide frames
With its extra-wide profile and durable galvanised finish, the UB5 U-bolt is a top choice for tradespeople, boat trailer owners, and off-roaders looking for a secure and rust-resistant mount. The included nuts make installation simple and efficient.

Guide-Recommendation
Evaluation & Recommendation
UB5 U-bolts are ideal for wider drawbars and shallow profiles, where extra bolt width is essential but depth isn’t required. Their short arm length is well-suited for low-clearance installations on large flat frames, like 130x50mm trailer drawbars or marine trailer A-frames.
If your setup requires deeper bolts or smaller widths, explore our U-bolt range or chat with our team to find the right match.
Installation Tip: Ensure all threads are free of debris before installation. Use a torque wrench to tighten evenly and prevent uneven clamping or frame distortion.
