Dicor's Versa-Lok® ABS Hub Covers provide great appearance coupled with the best retention system on the market today. Made of temperature-stable ABS plastic, Versa-Lok® Covers come in sizes to fit most trailer wheels. Rather than depend on friction fit like similar covers, the Versa-Lok® ABS Hub Cover actually locks onto the wheel with a simple twist. This patented attachment system allows easy access to the wheel hubs for checking or lubricating purposes without the potential damage caused by prying them off.
