Weld these trailer coupling plates to the top of your chassis rails, so you can bolt the coupling onto them.

At Couplemate, we stock over 1500 trailer spares to suit most trailer and caravans.

Buying and cutting flat steel can be expensive and time-consuming, When manufacturers cut plates to size and pre-drill holes in the correct position for your coupling, you save quite a bit. This is a practical solution for what would otherwise be a difficult job.

Coupling plates are generally 6mm; with chassis rails so close to each other, you simply won’t need thicker material.

Manufacturers pre-drill shackle plates as follows (no, we do not pre-drill these plates to different hole configurations).

  • 100mm for two-hole plates
  • 184mm x 52mm for 4-hole plates.

You weld coupling plates on top of the chassis rails, or under them. When you weld these under the chassis rails, they go between the chassis rails. This provides a lower attachment point for the trailer or caravan.
