Protect your trailer or caravan wheel bearings with the genuine Holroyd 1 ¾‑inch (45 mm) Hub Dust Cap. Designed for easy pressure-fit installation, this metal cap shields grease-packed hubs from dust, dirt, and water—helping to extend bearing life and reduce maintenance.

Key Features:

• Precision fit for 1 ¾‑inch (45 mm) hubs — engineered by Holroyd to suit lighter duty trailer and caravan axles. The press-fit design ensures a snug seal to keep contaminants out.
