If you want a durable, made-in-the-USA door restraint to keep your truck box lid from slamming shut, choose Buyers Products Company 3027065; if you need a robust, stainless steel lock replacement kit to secure your car audio gear and heavy tools in a truck bed toolbox, choose Loclink Truck Tool Box.
• Buyers Products Company 3027065: Strength lies in its aircraft-grade, PVC-coated wire construction that prevents over-extension of drop doors; trade-off is it is a single-component accessory, not a full storage or locking solution. This pick is for owners who already have a sturdy box but need a reliable safety tether.
• Loclink Truck Tool Box: Strength comes from its high-quality 304 stainless steel paddle latch and comprehensive replacement kit that secures the entire container; trade-off is the larger footprint and heavier weight compared to a simple lanyard. This pick is for anyone needing to replace a broken lock or upgrade security for valuable cargo like car audio systems.
This product is not a storage unit itself; it is a precision-engineered component designed to solve a specific mechanical annoyance. The core function of the Buyers Products Company 3027065 is to act as a door lanyard, keeping the heavy lids of drop-door and swing-door truck boxes from swinging too far open. Without this restraint, those heavy metal doors can slam back down with dangerous force, potentially damaging the hinges, the box, or your fingers. The design utilizes a universal fit with two swagged eyelets, meaning it is built to attach to most standard truck boxes regardless of the specific brand or model you own.
The material choice here speaks volumes about its intended lifespan. Constructed from PVC-coated galvanized steel wire, this lanyard resists rust and corrosion better than bare metal alternatives, which is critical for equipment sitting out in the elements day after day. The "aircraft grade" designation suggests a high tensile strength relative to its size, ensuring it won't snap under the tension of a heavy door. At just 9.63 inches long, it provides enough slack for the door to open fully for access but stops it before it becomes a hazard.
Who should buy this? If you are a contractor, landscaper, or weekend warrior who uses a truck box frequently, and you are tired of chasing a runaway door or hearing the dreaded clang of metal hitting metal, this is the fix. It is also ideal for those who value American manufacturing, as this item is proudly made in the USA. However, if you are looking for a new tool box, a locking mechanism, or a way to store items inside the bed, this will not help you. It is purely a safety and convenience add-on for existing hardware.

In contrast, the Loclink Truck Tool Box solution focuses on security and containment. This is a complete lock replacement kit featuring a stainless steel locking paddle latch, designed to be the primary barrier against theft and unauthorized access. The standout feature here is the material composition: the paddle latch is crafted from high-quality 304 stainless steel. This material is renowned for its resistance to corrosion and wear, making it suitable for harsh environments where salt, rain, and road grime are constant threats. The surface treatment is polished, which not only looks professional but helps prevent dirt from sticking to the mechanism.
What makes this particularly useful for serious users is the scope of the package. You do not need to hunt for screws, gaskets, or keys elsewhere; the kit includes everything required for installation: the lock itself, a gasket, two keys, four screws, and nuts. The dimensions are substantial, measuring approximately 5.85 inches by 4.25 inches, with a panel thickness requirement of between 0.08 and 0.2 inches. This ensures a solid fit across a wide range of truck boxes, RVs, campers, and utility vehicles like ATVs and UTVs. The compatibility list is extensive, covering everything from standard truck bed toolboxes to cargo haulers.
This product is essential for anyone whose current lock is broken, stripped, or simply insufficient for their needs. It is especially relevant for those transporting expensive equipment, such as car audio systems, power tools, or sensitive electronics. A standard padlock often lacks the integrated strength of a built-in paddle latch, which is why upgrading to this system provides a more permanent and secure solution. If you need to replace an old, failing lock mechanism and want a part that matches the durability of the box itself, this is the logical choice.

I would personally choose the Loclink Truck Tool Box for my own setup, primarily because I am using my truck for hauling car audio equipment and other high-value gear. While the Buyers Products lanyard is an excellent piece of engineering for keeping a door safe, it does nothing to stop someone from opening my box and taking my speakers. The Loclink lock provides a fundamental layer of security that a simple tether cannot match. Its 304 stainless steel construction feels rugged enough to last for years, and having the keys and mounting hardware included means I can get my box secured immediately. For anyone prioritizing the safety of their contents over the mechanical safety of the door hinge, the Loclink option is the clear winner.
