The 137mm U-Bolt Kit is 137mm when measured from the tip of the thread to the underside of the top.

The kit comprises

Four elements uniquely define any U-bolt, they are:

  1. Material type (for example bright zinc-plated mild steel or galvanised)
  2. Thread dimensions (for standard 1/2″ )
  3. Inside diameter (for example 50 mm – the distance between the legs)
  4. Inside height (for example 125 mm)

Mild steel stretches under load. It is essential you re-tighten u-bolts approx 200 km after installation.

  • The thread size is 1/2″ BSW.
