Rumber chocks are safer, better performing and more cost-effective than any option available. Unlike cheaper chocks that are hollow and made of rubber, Rumber chocks are completely solid throughout and made from an extremely durable composite. Other chocks are more likely to crack, rot or get crushed and need to be replaced frequently costing you more over time. Rumber chocks are just the opposite. They will never crack, rot and are virtually indestructible, so they’ll never need replacing. Bottom line, Rumber chocks are a safer product with a higher cost savings. If that isn’t enough, Rumber chocks are guaranteed forever with a no questions asked replacement policy. Yet another reason Rumber is the last chock you will ever buy.
