These are the same D rings I install in the trailers I sell, when I set them up for Holding down almost ANYTHING!
These D Rings weigh a little over 4.5 POUNDS a piece. Please Call or email for shipping quote if ordering more than 1. eBay usually over calculates for shipping.
Each ring is rated to 15,000# working Load, and 46,000 Max Load. The "D ring" part measures 3" x 4" INSIDE (5" x 6" outside), and is a full 1" thick (they are larger than they look in the picture!). If you are looking for a big Ring, this is the biggest one I sell!
I usually weld them right on a frame cross member for a strong mount. The price is for one, so buy as many as you want, shipping discounts for large orders.
1" Thick Loop
The weld on bracket is a full 1/2" thick, and is 2-1/4" wide and 2-1/4" long.
