4 Pack | D-Ring Tie-Down Anchors (Large Square), Recessed Pan Fitting D-Rings Heavy Duty Steel Cargo Tie-Downs,Truck/Trailer/Flatbed/Pickup Anchor, Note: Hardware NOT Included.

Delivered on time. Great cargo d-rings to secure cargo to or inside a transport trailer. These are far from being adequate for transporting heavy equipment such as a 10,000lb tractor or more. Backup plates on this particular item, not included and not needed. Let me explain why they may not be needed if the d-rings are installed according to the weight of the cargo.The back-up plates are only needed if the wood flooring is adequate for the weight of the cargo. Keep in mind, that "wood floor" is most likely not as strong as the steel/aluminum frame of the trailer. The weight of the cargo attached to a typical 3/4" (some 1/2") plywood will help decide what's more important in a hard turn, emergency stop, close call, a wreck, overturn, or jack-knife. 2nd are the tie down straps, how many, and their working load rating compared to the actual weight of the cargo. I transport up to 2 large 1,200 pound motorcycles in a 20 foot cargo trailer, (valued at $10,000 to $100,000) or 1 side x side up to 1,500 pounds. My cargo will be attached by at least 4 straps connected to 4 d-rings. I use a minimum of 4 with a working load of 1,000 pounds each (that's 4,000 pounds holding the bike to the d-rings collectively) Overkill to a point but, the key factor to keep in mind, are you attaching the load to the plywood or attaching the trailer to the load (more likely desired). When sht happens, cargo weight vs trailer weight, the heavier of the 2 is the controlling factor.With all this said, if you're hauling bicycles or a small riding mower (under 1,000 pounds) using 4 of them rated at 2,000 pound working load each (never use less than 4 for stability), attached to the plywood flooring without the back-up plate is good enough.With no reservation, I would recommend this set of 4 to anyone keeping the cargo vs trailer weight, and safety in mind.

I purchased 2 sets, three days apart, and ended up with a different set . The one on the Left came in first and has a spring , The second set came in with one lock washer that had no chance in 'D'ring heaven to touch enough to hold in place , I ended up placing a spring in place of the worthless one lock washer so it would not raddle its life away. Somewhere in the yokohama D-ring restaurant,I mean manufacturing things got a little confusing .I mig welded them in place and worked great . I was a little hungry after welding them in . They smelled a little bit like Teriyaki .

Excellent quality for the price, cheaper than local farm supply and same quality. See template, these are large, and will handle medium 1500lb. shackle or chain hook. Rings are spring loaded, so they retract.Happy with the product, this is an up or down vote for me.-Use a hole saw to install, I didn't need to modify the hole. Make sure you use grade bolts, large washers when mounting through 1.5" lumber on most trailers. Bolt half of the tie-down to the steel subframe if possible...be smart...if the item to which you are bolting these to won't hold the weight limit, then the product won't either...the working value listed is for the break strength of the product, not your installation.

Company really should add a cut out stencil with tie downs. It would make install much quicker and easier. Lost a star.

These tie down anchors are very sturdy and as described. They work very well. I did not need the backing plate for the loads I expect to secure. I made a cardboard template for the area to cutout which was time consuming. Including one with the anchors would be very helpful for the installation and surely wouldn't add much to the cost to package them.

These are sturdy and once installed they work well. However, the very oddly-shaped bottom side makes it difficult to cut out a proper recess for them. The bottom side is sloped sharply from the ring end to the hinge end, and the outline is difficult to manage with a circular shape under the ring and an oblong shape at the hinge side. In and of itself this odd shape wouldn't be a problem, but the 4 carriage bolt holes are so close to the recessed area that there is almost no room for the bolts to anchor into the wood. Also the odd shape combined with the proximity of the bolt holes means that a simple circular mounting hole won't work - either the mounting hole is too small for the anchor to seat properly, or the mounting hole is so large that it encroaches on the bolt holes. Ultimately you have to do a bunch of custom, near-precision woodworking to make a suitable mounting hole. It took me nearly an hour to get the first one installed in my trailer, and they didn't get much faster after that. I recommend looking for a different model that has a simpler shape for mounting and more clearance between the mounting hole and the bolt holes.

I haven't had a chance to install these yet, but I did inspect them closely. They're pretty beefy, have very nice form and finish, and I can guarantee that if you're securing something like an ATV or motorcycle or sled and were to get into a major accident, the tiedown straps would break before these d-rings would. I've been in skilled trades for over 20 years, I figure I have a fairly good idea about that.

I needed about 20 of these to finish my project on my new trailer. I had looked everywhere and found DC Cargo Mall had just what I needed and at a price I couldn't find lower anywhere. Forget what the installation instructions say on their website, it is much easier than that. I like 'em and I believe they will last as long as my trailer.
