These are much larger than expected however they provide even more piece of mind than I was originally aiming for which is al ways a good thing. I bought 4 of these and mounted them in the bed of my 01 ram 1500 short bed to secure up to 2 bikes at a time. Proved awesome value for the first 6 hour drive I used them loaded down with 2 brand new 300 xc-w's 2 weeks ago.
Purchased one of these to add another hitch point to my trailer for bike transport. Stoutly built with a nice finish. Way more than you need for light machines, but it never hurts. This is the largest you could use and still have it work with the carabiner clip straps, though. A couple of mine needed just a light filing to clear. You can get this same D-ring at local hardware stores, but RM's price is much better. Throw one on your next order that qualifies for free shipping, and you can't beat it.
This thing is HUGE! so im sure it would hold a couple bikes. I love it and its great for the the price. I gave it a 4 out of 5 because my carbiner clips on my tie downs will not clip over the D ring because its to big. I have to loop the strap through and hook back to the strap.
I couldn't tell from the picture but these are some serious rings. Very heavy duty. I bought them to add to my trailer as another tie down point and it's prob more secure than the trailer itself at this point.
These things are monsters! By the description they seem big but when I got them they were thick rings with thick metal bases that the bolts go through. These things could tie down a semi! They look a little overkill for my small single quad trailer, in fact I think they will outlast the trailer! Definetely a great buy and a great price. Easy to install just need to have bolts with nylon inserts on the nuts so they don't back out or lock washers for install.
This thing is a monster. I did not think it would be this big. the base plate is 1 and 3/4 inches by 3 and 3/8 inches. the actual D ring is 3 and 3/4 inches wide and 3 and 3/4 inches tall. it's about 5/8 of an inch thick too. it will definitely hold anything down and keep it secure too. i bought for chaining things down in the bed of my truck and i can only imagine what a pain it would be to try and cut through this. unfortunately it was a little to big to fit it where i wanted it which is why i posted dimensions.
