SmartStraps Surface Mount D-Ring, Heavy Duty, 3/8in Diameter, 5000lb, 9183, Black 2 Pack

I used these to hang a hammock on a stand that I built. They are very strong and seem to be well-made. Time will tell, but they are pretty beefy.

I use these in a very unconventional manner but they are absolutely fantastic and haven't found anything to match this quality!

Great product! Holds strong!

Strong and worth the price

These are crazy heavy duty!

very sturdy, more than I expected

Worked great for what I needed

Heavy duty 3/8 carriage bolts

I am using this product to mount and hang something from my brick wall, it worked perfectly for the application. It does come in 2 pieces (ring and plate to mount) so it was a little tricky to get mounted but worth it for quality and strength.

Very strong and well made. I only wish the D-ring was contained on the back of the strap. It isn't a problem if you are mounting these on a flat surface. Your mounting surface holds the D-ring in place. If you surface dips any between the mounting bolts like mine, the D-ring isn't held. I had to fabricate flat back plates to go under these for that purpose. I believe these would be much more versatile if designed with the D-ring contained. I was very surprised to see there was nothing actually holding the D-ring in place unless you mount it on a flat surface. Even then, the loose ring just rides against your paint, and will wear it off just due to vibration.
