Need extra clearance between your bike carrier and the rear of your car? The Holdfast Base Plate Extension gives towball- and baseplate-mounted carriers the reach they need to clear a rear-mounted spare wheel — a common issue on SUVs and bakkies. Three lengths cover almost every fitment scenario.

Who It’s For

The extension works with any of our baseplate- or towball-mounted bike carriers where spare-wheel clearance is a problem, including:

  • Snap-On — our clip-on rear carrier range.
  • Hanging Racks — towball-mounted vertical carriers.
  • SA2018 — our flagship towball platform carrier.

Specifications

  • Lengths available: 12cm (SKU 220810) · 20cm (SKU 220820) · 30cm (SKU 220830)
  • Tensile tested to 3 tons — engineered for full-load carrier use
  • Hardware: stainless steel for long-term corrosion resistance
  • Finish: black powder coating matched to Holdfast’s baseplate range

How to Choose the Right Length

Measure the gap between your existing baseplate or towball and the point at which the carrier would contact the spare wheel. Round up to the next standard length. The 30cm extension suits deep rear-mounted spares on 4x4s; the 12cm handles most smaller SUVs and sedans.

Pair With the Right Accessories

Match the extension with bike carrier accessories like stabilising straps, cam straps, or number plate holders. For fitment queries, use our Find Your Fit tool.

Peace of mind on the road: the right extension means your bikes are secure, spare-wheel access is preserved, and nothing scrapes on the car during transit.
