Mackay WCS100 Rubber Wheel Chock, EPDM, Duro 70
Available
Mackay wheel chocks are made from moulded black EPDM rubber, which Mackay says gives high UV resistance and longer life (manufacturer-stated). They are available in multiple sizes, suitable for light and heavy duty vehicles such as cars, utes, caravans, buses and trucks (manufacturer-stated).
The store lists four part numbers, WCS100, WCM150, WCL150 and WCXL400. Mackay says to always use wheel chocks in pairs and notes that the width (B*) is also available in selected widths (manufacturer-stated). The two Mackay catalogues print different dimensions for these part numbers, so both sets are shown in the table.

Length (A), width (B*) and height (C) are in millimetres from the Mackay Vibration Isolators catalogue (Industrial Edition 09/2026). The earlier Industrial Rubber Technology catalogue prints different dimensions for some of these part numbers, and also gives the Duro and weight, which the newer catalogue does not. The earlier figures match the size shown in the store option. Contact Mackay to confirm the size before ordering where fit matters. Mackay prints all properties as nominal and asks you to contact them for technical advice.
Selecting the right option
Match the chock to the tyre and the vehicle. Mackay does not publish a vehicle weight, tyre size or holding-load rating for these chocks, so check the size with Mackay, especially for heavy vehicles. Always use them in pairs (manufacturer-stated), and because the two catalogues differ on dimensions, confirm the size before you rely on it.
