How To Install D-Rings in A Trailer

Do you want to install D-rings in your trailer? If you want to know how-to install D-Rings, then it is best to read this easy step-by-step guide on how-to install D-rings in a trailer.

What is a D-Ring?

D-Ring, as the name suggests, is a 'D' shaped piece of cargo securing hardware that is either mounted directly to the surface of a trailer or secured to a D-ring tie-down strap. It enables the user to customize his trailer's configuration with load-specific trailer tie-down anchors. That is why D-rings are also called Ring Anchors.

The working of D-ring is quite simple. All you have to do is to pull it up in an upright position so that you can hook a tie-down with it. When you are not using it, simply push it back so that it gets leveled down with the floor.

Installing D-rings in a Trailer

Step 1: Choose the best location in your trailer to mount your new D-ring tie-down. Just check the underneath of your trailer to ensure that there isn't anything in the way that won't allow you to put the backing plate underneath or to drill a hole.

Step 2: Measure the exact location on which you are going to have d ring installed.

Step 3: Take a pilot bit on a hole saw (hole cutter) and drill down before the hole saw is used to cut the hole (it is recommended to use 3-1/4 inch hole saw).

Step 4: If the trailer floor is made of plywood, you could drill all the way through. If you do not want to do it, then you can simply drill halfway through the board. Once you are done with it, the center section should be chiseled out before you start drilling holes.

Step 5: Once you have 3-1/4 inch hole drilled, set D-ring's top half into the hollowed place.

Step 6: You'll notice that each side of the hole is hitting the bolt that holds the actual loop in place. Remove a little bit of all parts that are hitting the bolt. As a result of it, you'll see that D-ring's top section will drop down flat with the surface.

Step 7: Mark out holes from the top section of D-ring to drill them and to put bolts through them. Use suitable bolts along with nuts and lock washers to be used on the underside.

Step 8: Put your backing plate underneath the trailer and make sure that it is lined up with the holes you just drilled. Put two or three bolts in it to keep it in place. Put lock washers and nuts on each bolt. Now that all the hard work is done, simply tighten the bolts, and there you have it- a perfectly installed D-ring in your trailer.

The Bottom Line for You

Needless to say, when there is talk about vehicle recovery or anything related to it, the importance of D-rings cannot be neglected or underestimated. Installing D-ring in a trailer is not that much difficult. However, you have to make sure that the measurements are taken correctly to avoid any unnecessary damage to the trailer floor. This guide applies to almost all types of D-rings. If you prefer a service professional install your D-rings, contact NC Trailers for a service appointment.

Had the pleasure of buying our first trailer for our new business from them this weekend. And let me say I can’t say enough about this company. From the first call with Donna, till we drove off the lot hooked up, they were absolutely amazing! Their inventory is intensive yes, but the customer service is extraordinary! Our purchase experience start with a transfer to Zach who was welcoming and extremely knowledgeable! Shancie took care of the financing and made everything so easy and simple, and Tammy was fast with our paperwork! Noah and Ryan went above and beyond for the install and hookup of all the accessories we choose! These folks are the best around and hire the most wonderful crew! Highly recommend them for any trailer purchase or service needs!

I would like to take a minute and recognize several people at NC trailers. From the start it was Zach & Sam in sales which went above and beyond the process of helping me pick the correct trailer and helping me complete all necessary paperwork when I was literally 1800 miles away driving down the road.

Shanice in financing made financing the trailer simple and quick, and behind the scenes Tammy in tag/title department was doing her magic so it all came together as one cohesive unit the day of picking the trailer up.

Speaking of picking up the trailer, Ryan & Noah truly went above and beyond expectations working in the pouring rain, while not compromising standards of making sure everything went smoothly and that I was hooked up correctly while taking the time to fully go over every aspect of the trailer and how to hook and unhook the trailer.

Tyler in Service & Parts was very helpful with information regarding the Gooseneck hitch for my next trailer.

Thank you to each Team member of NC trailers. I HIGHLY recommend this company to anyone needing a trailer.

So, if you need any type of trailer, accessory or even a repair, NC trailers should be your First and only stop. They truly make you feel like Family and the trailers are rated top in the Industry and priced very reasonably.

Head on over to NC trailers and get your trailer today. Tell them Mitch with a “M” not a “B” sent you, and you should receive an extra smile or two.

I have to say I had great experience with the staff at NCtrailers in Thomasville, NC. The staff up there were amazing. I had the pleasure of being David’s first sale for his new career dealing in this type of equipment. He has had many years in sales and it shows but he decided to venture into a new atmosphere of sales. Working through the contract side of things Shanice was very thorough and was able to give me all the details I needed. She was so inviting and made you feel comfortable through would could be a stressful process.

Tammy was a sweetheart with the tag and title paper work and talked me through all the necessary links and info I would need to setup the last little bit of info.

Ryan and Noah had me all hooked up and ready to go and even took the time to help me find a short in my connection on my truck so I would be comfortable knowing all the lights and everything worked properly on the new trailer.

All in all I had a great experience with the entire staff from parts to sales to service. I will most definitely be recommending them to anyone I know for their trailer needs.

Now wish me luck on my lawn care company venture.

After searching many sites, I settled on calling NC Trailers of Thomasville, NC. Zach was very helpful over the phone answering my questions. After I decided on a trailer I drove 3 1/2 hours to arrive at their location only 30 minutes before they closed. They didn’t mind my late arrival or staying to complete the sale. I changed my mind on the trailer I wanted and Shaun was very quick to redo all the paperwork for the sale. Noah was also helpful in going over the trailer with me and answering questions I had. And thank you Tammy for saving me a trip to NCDMV, at NC Trailers they can do your DMV registration and you leave with tags already installed. The trailer pulled smoothly all the home.

This company was great! Zach showed us great options, and helped us pick the perfect trailer for our needs. Shawn explained all of the extra packages we could add to it, and finalized the contract. Tammy did a great job at making sure we had our title, tag,and registration taken care of. And, Ryan and Noah got us hooked up and ready to go. Because they have an on-site parts and service department they were able to install the needed brake controller the our truck wasn't equipped with. Wonderful place. Will definitely recommend!
