Video Transcript for Buyers Products Tie Down Anchors - Trailer Tie-Down Anchors - 337B40 Review

Speaker 1: Today we're taking a look at a Forged D-Ring with a Weld-On Mounting Bracket. Now this allows you to secure a load with confidence using the five-eighth inch forged D-Ring. The D-Ring includes a weld-on mounting bracket. The units are made from durable steel construction with plain finishing. The D-Rings are not approved for overhead use, so please keep that in mind.With this one you'll get a maximum load or break strength rating of 18,390 pounds, and a safe working load limit of 6,130 pounds. Again, the ring diameter is five-eighths of an inch.

A few measurements to go over with you real quick. The available space internally, edge to edge, is about three inches by three inches. External measurements is about four and one-quarter by four and one-quarter, and then the bracket right here, edge to edge, going in this direction is around two and a half inches. Edge to edge this direction, right around an inch and a half, and the overall height of that weld-on bracket is an inch and a quarter, right in that area.Again, it's made from durable steel construction with plain finishing, and the product is made in the USA.That's going to do it for today's look at the Forged D-Ring with a Weld-On Mounting Bracket.

Customer Reviews

Buyers Products 5/8" Forged D-Ring With Weld-On Mounting Bracket - 337B40

Average Customer Rating:  4.8 out of 5 stars   (17 Customer Reviews)


I specifically purchased these D-rings as they are made in the USA. The pictures on the website show that the D-ring is embossed with USA on it. I am disappointed that the product I received does not have USA embossed in it. In the world of rigging (at least for overhead) if it doesn't say USA we do not use it. I double checked to ensure I received the correct product and product skew matches.

At the end of the day, these are oversized for my needs so they will work fine.

Thank you for your review. I did contact Buyers and this particular d-ring is manufactured in the USA.
-- Etrailer Expert Heather A - 03/05/2021


This tie down is well made and heavy duty enough for the applications we needed it for. We would recommend this product and this company.


Yep. I asked if the D rings they show on line are the ones they're sending me as I wanted to be certain of the product being mfd. in the USA. Better forging material and proper heat treating. They sent what they said. They are being welded to 1/4 inch steel framing on a flatbed. Needed the 5/8 inch diameter as some serious loads require secure bullet proof attachment points. Prompt delivery. Been a customer several times with them. No disappointments.


Good tie downs still hanging in there


product was delivered as advertised. But then, as soon as the order was made, I received an email letting me know that they "bumped" me from ground shipping to the next faster category without charge (who does that anymore?). The package arrived quickly, and in tact. Very satisfied customer.


Great transaction as usual. This is not my first order from this company. And as the norm is with them very quick free shipping. Good prices and great products.


Easy to install
Worked great


Good quality,exactly what I expected


Shipped fast, after one year still working good.


Arrived quick. Described correctly


D-Rings are great quality and work well.


Well built, versatile, exceptionally st rong







Ask the Experts about this Buyers Products Tie Down Anchors

  • What is the Capacity of Buyers Products 5/8 Forged D-Ring 337B40MP
    The Buyers Products 5/8" Forged D-Ring # 337B40MP has a working load limit of 6,130 pounds. The break strength data was not provided. Usually the working load limit is a third of the break strength but again the exact figure is not provided. The capacity will also depend on what you have the D-ring mounted to. So for example if mounted to a steel frame you will likely be able to reach the WLL capacity. Attached to 1/2 inch plywood, not so much.

  • Does Buyers Products 5/8" Forged D-Ring # 337B40MP Have Capacity for Transporting Rock Crawler
    The Buyers Products 5/8" Forged D-Ring With 4-Hole Integral Mounting Bracket # 337B40MP that you referenced has a 6,130 lbs working load limit which would easily be enough for a Jeep rock crawler. Especially when you consider that you'd be using more than one and one by itself would have more than enough capacity.

  • How to Install the Buyers Products Hour Meter B40B45
    The Buyers Products Hour Meter part # 337B40B45 can be wired to any 10-80 VDC accessory that you need to monitor the run time on. It is primarily used for equipment maintenance and repair schedules. It will simply install inline on a power wire that leads from the power source to the accessory. For example, instead of running the accessory directly to the battery you would tie into the meter first and then run it to the battery which you can see in the attached photo.

  • Frame Mounted Forged D-Ring Tie Downs on Big Tex 70 Steel Car Trailer
    I can absolutely help you and make a recommendation. The floor of your Big Tex 70 car trailer is an 1/8 diamond steel plate. The 1/8 plate will be fine for a tie down point for anything but a car. You need a bracket not to fasten something down tight but to keep your car from moving. The rolling resistance would be too much for an 1/8 plate but sufficient for any type of other loads, like lumber, drywall, trash, pipe etc. You're going to need to drill into the frame to safely secure mounting...

  • Can Curt C45832 Tow Strap Loop Be Used to Tie Down a UTV
    The # C45832 strap loop itself has a 13K capacity, so the strength of this part itself wouldn't be an issue. If the combined capacity of the receiver hitches is greater than the 2370 lb dry weight of your UTV, this would be a good way of tying it down. If the receivers don't have that kind of capacity, I'd use a more traditional tie down setup like a couple of D-rings such as # 337B40MP and two ratchet straps like # BDW20325. You could rig it up as shown in the provided video.

  • Recommended Trailer Tie-Down Anchor That Is Made In The USA
    I have another option for you, but most of our Tie-down anchors including the Brophy D-Ring Tie Down Anchor w Backing Plate - Bolt-On - 1/2" Wide - Recessed - 1,600 lbs # RR5K are made overseas. For an option that is made in the USA I recommend the Buyers Products 5/8" Forged D-Ring With 4-Hole Integral Mounting Bracket # 337B40MP which has a 6130lb working load limit (WLL) meaning it will be plenty strong for securing your 2000lb tractor. I included a video of the # 337B40MP for you...

  • Recommended Solution for Tie Down Anchors to Use Wheel Nets on Aluminum Trailer
    I recommend using e-tracks like the Erickson Horizontal E-Track - Zinc Plated Steel - 2,000 lbs - 5' Long # E19148 because of the flexibility these provide you in regards to getting your UTV positioned. Because these are zinc plated steel, there won't be any corrosive reaction with your aluminum trailer, so there's nothing to worry about in that regard. I do recommend using the E-Track Backing Plates # e96RR. I do believe that this will also require less drilling than drilling 4 holes each...

  • Torklift or Other Product for Holding Camper on a Flat Bed F-550
    I would use the Buyers Products # 337B40MP forged D-rings with brackets in the four locations where they are needed. You could install into metal deck framing, or into typical 2-by lumber materail which itself has been secured to the fram of the truck. Then you could potentially use 4 Cargo Buckle # IMF14069 tie down straps rated for 2200 pounds each. Not only would these hold a camper on the flat bed, but when the camper is out, these parts will help secure other loads. You will need...
