Review on 🔒 4 Pack Large Square D-Ring Tie-Down Anchors: Heavy Duty Steel Cargo Tie-Downs for Trucks, Trailers, Flatbeds, and Pickups (Hardware Not Included) by Jim Polacek

Delivered on time. Excellent cargo D rings for securing cargo to or in a transport trailer. They're nowhere near enough to carry heavy equipment like a tractor weighing 10,000 pounds or more. Lock plates on this particular product are not included and are not required. Let me explain why they may not be needed if the D-rings are adjusted according to the weight of the load. Support plates are only required if the wooden floor is sufficient for the weight of the load. Keep in mind that a "wooden floor" is probably not as strong as a trailer's steel/aluminium frame. The weight of a load attached to a standard 3/4 inch (about 1/2 inch) plywood will help determine which is more important in a tight turn, emergency stop, close range, crash, rollover, or jackknife is. Second, the number of lashing straps and their rated working load compared to the actual weight of the load. I tow up to 2 large 1200lb bikes in a 20ft cargo trailer (costs $10k-100k) or 1 side x side up to 1500lbs. My load is secured with at least 4 straps connected with 4 D-rings. I use at least 4 with a working load of 1000lbs each (that's 4000lbs when the bike is held together by the D-rings). This is an exaggeration to a degree, but the key factor to keep in mind is that you are attaching the load to the plywood. or attaching a trailer to the cargo (rather desirable). In this case, the weight of the load versus the weight of the trailer, whichever is heavier, is the deciding factor. That being said, if you are transporting bikes or a small mower (less than 1000lbs), use 4 of them rated at 2000lbs. Load per piece (never use less than 4 for stability) attached to a plywood floor with no bottom board is sufficient. Intelligence.
