Draper 50mm Swivel Bolt Fixing Rubber Castor with Brake. 12mm bolt diameter swivel bolt fixing. Non-marking rubber tyres. Sold in polybag with label.
To calculate the safe working load (SWL) for each castor take the weight of the load in kilograms and divide by the number of castors minus one,
100kg divide by 3 (4 wheels minus 1) = 33kg.
So each castor would need to be rated at a maximum S.W.L of 33kg.
