Replacing an old castor? Measure between the centres of two fixing holes along the long edge, then across the short edge, and compare with the hole centres above. Allow the swivel radius as clear space around each castor so it can turn freely.
Load check
How we work it out: on a real floor one castor is often carrying little or nothing, so we share the weight across one fewer castor than you fit (with 3 castors, across all 3). Tick the box to add a 30% margin for rough use.
Floors & use

- Cushions the load and soaks up vibration
- Quiet on most surfaces
- Copes with uneven floors, thresholds and outdoor use
- Good grip on smooth floors

Frequently Asked Questions
How do I fit a bolt hole castor?
Pass an M10 bolt through the 10mm hole in the top of the castor and secure it into your furniture, a threaded insert or a tube adaptor fitted inside the leg.
How much weight can a set of four carry?
Each castor is rated at 60kg. For a set of four we recommend a maximum of 180kg, as only three castors are usually in full contact with the floor at once.
Is the grey rubber wheel quiet and floor friendly?
Yes. The grey rubber tyre rolls quietly and is gentle on wood, vinyl, tiled and other smooth indoor floors.
Does this castor have a brake?
No, this is a plain swivel castor. For equipment that needs to stay in place, pair it with braked castors of the same size.
What is the total height of the castor?
The total castor height is 72mm from the floor to the top of the fitting, which keeps equipment low and stable.
Is this castor suitable for outdoor use?
It is best suited to indoor use on smooth, level floors. For rough ground or outdoor areas, choose a larger wheel.
