When you need heavy duty, durable trailer tie down anchors for your trailer, look into Flush Mount Recessed Stainless Steel D-Rings in a 4-Pack from US Cargo Control. D-Rings are an essential component of many trailer tie down systems, allowing you to customize your setup by placing attachments where you need them. While they are commonly used as anchor points for your tie down straps, d-ring tie down anchors can secure cargo and vehicles for storage or transport. They are also ideal for increasing load efficiency - if you move the same type of cargo, adding permanent trailer anchors can simplify the setup process. Our d-rings heavy duty are recessed and flush mount, meaning they won't get in the way when rolling items on and off the trailer (recessed) and the flat part of the fitting is designed to fit flush against the surface (flush). The recessed tie down anchors are made out of Type 316 stainless steel, which will withstand corrosion and rust well in marine environments. Note that Type 316 stainless steel forms a passive layer of corrosion on the surface but it does not accelerate to the core of the product, extending the life of the d-ring in high moisture environments. With a working load limit of 266 lbs. and assembly break strength of 800 lbs., the trailer anchors will act as anchors in your load securement setup. Use the tie down anchors for trailers, garages, sheds, enclosed trailers, and workplaces. Secure a variety of items including cargo, light motorcycles, ATVs, recreational vehicles, snowmobiles, hanging tools, and lawnmowers to be secured during transportation or storage. The flush mount tie down anchors are compatible with tie down straps and most ratchet strap end hardware, including S-hooks, snap hooks, grab hooks, and more. The next time you need to secure cargo or items inside your trailer, garage, or shed, US Cargo Control's Stainless Steel D-rings will help create anchor points and simplify the setup process.
