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.
