We can ship to virtually any address in the world. Note that there are restrictions on some products, and some products cannot be shipped to international destinations.
When you place an order, we will estimate shipping and delivery dates for you based on the availability of your items and the shipping options you choose. Depending on the shipping provider you choose, shipping date estimates may appear on the shipping quotes page.
Please also note that the shipping rates for many items we sell are weight-based. The weight of any such item can be found on its detail page. To reflect the policies of the shipping companies we use, all weights will be rounded up to the next full pound.
You may return most new, unopened items within 30 days of delivery for a full refund. We'll also pay the return shipping costs if the return is a result of our error (you received an incorrect or defective item, etc.).
You should expect to receive your refund within four weeks of giving your package to the return shipper, however, in many cases you will receive a refund more quickly. This time period includes the transit time for us to receive your return from the shipper (5 to 10 business days), the time it takes us to process your return once we receive it (3 to 5 business days), and the time it takes your bank to process our refund request (5 to 10 business days).

Protect your assets and prevent trailer theft with our Heavy Duty Kingpin Lock. Designed for fleet owners, owner-operators, and logistics managers, this lock provides an impenetrable physical barrier that prevents any unauthorized fifth-wheel coupling. Whether your trailer is sitting in a yard, at a truck stop, or on a job site, this high-visibility security tool ensures your cargo stays exactly where you left it.
Forged from high-grade steel, the "cup" design completely sleeves the kingpin, making it impossible for a tractor to engage. Its robust construction is specifically engineered to resist bolt cutters, saws, and hammer attacks.
High-Strength Steel Construction: Built with a heavy-duty casting that withstands extreme physical force and tampering attempts.
Universal Fit: Precision-engineered to fit all standard kingpins on semi-trailers, RVs, and fifth-wheel campers.
High-Visibility Finish: Coated in a bright "safety yellow" or "caution orange" to alert potential thieves from a distance that the trailer is secured, acting as a powerful visual deterrent.
Pick-Resistant Cylinder: Features a specialized lock cylinder that is resistant to picking and drilling, providing an extra layer of professional-grade security.

🛑 Pro Tip for Maximum Security
To ensure long-term reliability, occasionally spray the lock cylinder with a dry graphite lubricant to prevent sticking caused by road salt or debris. Always keep the bright finish clean; a highly visible lock is your first line of defense because most thieves will move on to an easier, unsecured target rather than risk the time it takes to defeat a physical lock.
