Robbor D Ring Tie Down Anchor 4 Pack – Heavy Duty 6000 lbs Breaking Strength, Surface Mount Tie Down Ring for Trailer Cargo Control, Motor Bikers, ATV's Review

Put them on my trailer to tie my Can-am x3 Max. Fairly easy to install with 3/8" carriage bolts, flat washers and lock washers. Definitely recommend for this use case.

These D-rings will do the assembly. The only reason I gave it 4 stars for ease of installation is because I installed steel back plates under the trailer floor for extra strength.

Thick, strong, well finished surface! BIG! Thick, very nice strap rings, the plates are strong and well made. Exactly what I needed and way more than I expected. I can't wait to put them on and get them working!

I installed them on a new trailer that I use to transport my Polaris RZR. These things are so strong I have no doubt you can lift the entire trailer off the ground with these anchors! This RZR stays in place no matter how hard the trailer hits it during transportation.

D-rings fit and work properly. I can't say anything about durability as they have just been installed and haven't been exposed to the elements for a very long time. They are strong but probably overkill for use on my car carrier to protect my portable generator. I definitely recommend this product.

They're pretty powerful. I used them as anchor points to secure myself next to the trailer. There are bigger and thicker ones, but at a price. They seemed like a good compromise that was strong enough and not too expensive. In fact, they seem strong enough - and are rated - so I bought class 8 nuts and bolts to secure them. I figured there was no point in breaking strong anchors because of the clamp fittings.

I used them as mounting points for a 600 lb bike on a backcountry ride. They arrived on time, were as described and did their job for the bike. I'm sure they will carry more weight if needed, but I enjoy using them (and they are now attached to my trailer for future use). They didn't come with trailer fasteners (screws) but a quick visit to the hardware store and I got what I needed.
