Measure the installation area and compare it with the product dimensions, hole spacing and mounting requirements. If unsure, send us your measurements and product code before ordering.
Useful measurements may include overall length, width, height, hole-to-hole distance, mounting depth and material thickness. A clear photo with a ruler can also help identify a suitable replacement.
A different model may work if its dimensions, mounting points, function and load requirements are compatible. Compare the specifications carefully and seek advice before modifying an installation.
Check the overall size, centre-to-centre hole spacing and the proportion of the fitting to the door, drawer or panel. Match the mounting measurements first, then choose the preferred design and finish.
Measure from the centre of one mounting hole to the centre of the other hole. Do not measure from the outside edges, as this can give the wrong replacement size.
Consider the panel material, thickness, opening direction, mounting space, frequency of use and desired finish. Use the product dimensions and installation method to confirm compatibility.
Consider the total load, number of wheels, floor condition, wheel diameter, mounting type, movement direction and whether a brake is needed. Confirm the model specifications for your application.
As a basic guide, divide the total loaded weight by the number of wheels, then allow a safety margin for uneven floors and changing loads. Confirm the rated capacity of the exact model before use.
Fixed castors move mainly in a straight direction, while swivel castors rotate to change direction. Many applications combine both types for stability and manoeuvrability.
A brake is useful when equipment must remain stationary during loading, use or storage. Check whether the brake locks the wheel, swivel action or both, and select according to the operating environment.
Consider floor hardness, unevenness, debris, noise and marking concerns. Wheel material and diameter affect rolling performance, so match the exact castor specifications to the floor and load.
Outdoor suitability depends on the material, coating and exposure to rain, humidity, chemicals and sunlight. Confirm the product specification and use appropriate corrosion protection for the environment.
Keep the hardware clean and dry, avoid harsh chemicals, repair damaged coatings and use suitable protective products when required. Regular inspection is especially important in humid or corrosive environments.
