Short Product Summary

The Holdfast Base Plate Extension adds extra reach between a towball- or baseplate-mounted bike carrier and the back of the vehicle, clearing a rear-mounted spare wheel. It comes in three lengths to suit different vehicles, and is aimed at SUV and bakkie owners whose spare wheel sits in the way of the carrier.

Why This Product

A rear-mounted spare wheel takes up exactly the space a towball carrier needs to sit in, and without extra reach the rack can end up resting against the wheel instead of clearing it. Rather than a one-size fix, this extension is offered in different lengths so you can add just enough distance to get the carrier clear without the load sitting further out than it needs to.

Key Features

  • Adds reach behind the vehicle – clears the carrier from a rear-mounted spare wheel
  • Three lengths to choose from – 12cm, 20cm or 30cm depending on how much clearance you need
  • Tensile tested to 3 tons – built to take a fully loaded carrier's strain
  • Stainless steel hardware – resists corrosion over time
  • Black powder coated finish – matched to the rest of Holdfast's baseplate range

Ideal For

  • SUV and bakkie owners with a rear-mounted spare wheel who need extra clearance for a towball or baseplate carrier.
  • Anyone whose current carrier rubs or catches on the spare since the right length extension moves it clear.
  • Owners fitting a Snap-On, Hanging Rack or SA2018 which are the baseplate- and towball-mounted carriers this extension works with.

Optional Fitment / Upgrade Notes

Before ordering, work out the right length:

  • Work out how far your carrier currently sits from the spare wheel, and pick whichever of the three lengths clears that gap.
  • A deeper spare on a 4x4 typically calls for the longest option, while a smaller SUV or sedan is usually fine with the shortest.
  • Confirm your carrier is a baseplate- or towball-mounted type, since roof-mounted carriers don't use this extension.

FAQ

What does this extension do?
It adds distance between a towball- or baseplate-mounted carrier and the vehicle, so the carrier clears a rear-mounted spare wheel.

Which length do I need?
Work out how far short your carrier currently falls of clearing the spare wheel, then choose whichever of 12cm, 20cm or 30cm covers that.

Is it strong enough for a fully loaded rack?
It's tensile tested to 3 tons.

Will it fit a roof-mounted carrier?
No, it's for towball- or baseplate-mounted carriers such as a Snap-On, Hanging Rack or SA2018.
