Video Transcript for Brophy Backing Plate Review

Today we're going to be taking a look at the Brophy Backing Plate designed for use with the recessed 5,000 pound D-Ring tie down. This part number is BP05. As you can see the four bolts that come through our tie-down are going to run right through our backing plate, allowing us to put on a lock washer and a nut and really spreading out that holding force over a greater area. As you can imagine if we just had the four bolts coming through here we'd be limited in the amount of space that was actually holding our tie-down down. Once we have this incorporated it's going to spread that our, dissipate that energy and give us a good, strong tie-down connection point. This works great in an enclosed trailer which we are using today. Also just about anywhere else that you've got the room to put that backing plate behind your D-ring where you need a hold down connection point. Here's that part number RR05.

That's that Brophy 5,000 pound recessed D-Ring. Here you can see the four bolts that are coming through this right down into our backing plate. Now that we've seen what it does and how it's going to work, that's going to complete today's look at the Brophy Recessed D-Ring Backing Plate, right here, part number on that is BP05. .

Backing Plate for Brophy Recessed D-Ring Tie-Down Anchor - BP05

Average Customer Rating:  4.9 out of 5 stars   (56 Customer Reviews)

Zinc-plated steel backing plate reinforces a Brophy recessed D-ring tie-down anchor (RR05). Plate bolts on underneath the floor of your trailer to reinforce the area under the anchor for maximum support. Mounting hardware not included.


Product appearance and workmanship met all expectations. All four (4) BP05 items were consistent in quality and dimensions. The BP05 provides reinforcement of load anchor points when an anchor can not be fastened to a frame-member of the trailer's chassis.

After a year of use, there has been no problems with the BP05. Not much hauling for car shows in the past year, but I did head to the Rocky Mountains to pick up another antique car, a 5,000 lb. land yacht. An emergency stop on the interstate highway while descending the mountains put the load anchors and BP05s to the test. All is well.

While I had to wait for supply delay issues, they are worth it. My new ATC trailer came with 4 tie-downs and backing plates exactly like these. I have used the trailer with a car and look forward to adding these 8 additional tie-downs for motorcycles. They are of great quality and function properly.


Good, solid hardware.


Just what we needed, gives excellent support on our wood and metal floor trailers and truck flatbeds! Will buy again.


Recently ordered D rings and backing plates for my enclosed trailer. A quality product and quick shipping, but most impressive was the customer service. I would rate the items ordered as 5 stars. However, the etrailer customer service is 10 stars.


I went to a local store and bought four tie down anchors to put in my enclosed trailer. I also bought all the hardware I thought I would need to install them. Upon returning home, I went on line to learn the proper way to install them. That's when I found out that I needed a backing plate which was not offered to me at the local store. I ordered a set of four from I received them in the expected time and they are now installed and I am very pleased with the product. The bolts I bought were a little bit long and because of the thickness of the flooring I had to cut all the way thru. I used bathroom tub and tile caulk to seal the hole and wood underneath and I will paint it after the caulk cures. You can buy the entire kit from which is what I should have done. I guess you learn from your mistakes.


This is a good compliment to the D ring s.


I had purchased the RR05 at a local retailer, but they did not have the backing plate, so I ordered from e-Trailer. In retrospect, I wish I had just ordered the RR05 kits from e-trailer. The ordering process is simple, great email comminication during order & shipping processing, and very fast delivery.

(I worked on my trailer in the garage during Huricane Irene, and completed installation of 5 of these D-Rings. )

Thanks e-trailer. Great site!


Works great for our enclosed trailer for our tie downs

Great backing plate and a must for wood floor trailers !


My backing plates arrived on time. Although I did not buy the tie downs from etrailer the backing plates fit perfectly. I would recommend etrailer. I am very satisfied with this purchase thank you.

by: is an easy company to do business with. I found their product pricing and shipping costs to be fair. Shipping and communication was good. I would use again.


I could not find these anywhere locally. This will work well with the d-rings I'm mounting in the floor of my trailer. Ideally these could be welded to the frame for maximum security but through 3/4" flooring I don't expect any problems. Thanks for the fast service!


I received the set of 6 BP05 D-Ring backing plates very quickly and they are a very heavy duty plate with a nice zinc corrosion resistant coating. I am very pleased with etrailer.coms service and commitment to providing quality items at a reasonable price. Mike


Would not buy tie down rings with out the backing plates


Quick delivery! Great shopping experience! Price was 1/3 what the local trailer dealer wanted and I was able to get the backing plates as well. Saved me a lot of money!


Excellent service from order to delivery. There was much follow up and notification of the status of the order. I am a military officer who loves follow up and follow thru and I think you have this process nailed!


These backing plates are thicker than the ones that came in my toy-hauler, which makes them much stronger. These plates are plated , instead of painted as well, which makes welding easier if that's your intention, as I did. Way better quality than expected. Thanks!


Got it quick, fit great, works great. Will be a return customer and highly recommend!

The product seems to be working great. Thanks for reaching out!

these were the wrong parts I needed. I talk to Allison in customer service and she offered to allow a return I declined but she help me order the correct backing plate and processed the new order. Allison extremely helpful, pleasant to deal with and took care of my issue without any problems...Great help


These plates are worth every penny. They were installed on a trailer that didn't have support plates on the tiedown.


Worked perfectly with the RR05 D-Rings. Excellent for distributing the force of the mounting bolts to a greater area.


It does not fit the D-Ring it is supposed to reinforce other wise I am sure it would work just fine. This came unwrapped in a box full of shiny polished Plastic parts. Fortunately it was a short distance and the single layer plastic wrap prevented any damage.


You have to have this to complete your D ring install.
