No matter what size aircraft you need to safely secure we have aviation wheel chocks for you if it is a small personal aircraft or the largest of military transport planes we have heavy-duty chocks for your application. Our aviation wheel chocks come in a wide variety of weights and sizes but what they have in common is that they are all made of high-density urethane plastic. Urethane is designed to have complete resistance to most common aircraft fluids and will not degrade, even when faced with years of harsh weather. You cannot compare urethane aircraft wheel chocks to their cheap wooden alternative. Wood wheel chalks often wear down over time and pose the risk of splintering, possibly causing FOD or foreign object damage. Therefore, for smaller vehicles such as trucks and trailers, we also offer rubber chocks at affordable prices.
