6 Pieces Single Stud Fitting L Track 4,000LB Capacity with Stainless Steel Round Ring Aluminum Keeper Cargo Control for Airline Track Logistic Installation

I use them in my Sprinter van, in the L track, to tie stuff down.

strong enough to hold boxes down in my Jeep's cargo area

Fits perfect with the cargo track I purchased.

Nice sturdy O-track hold downs. Perhaps not as nice as the Genuine Ancra ones, but good and much less expensive.

Bought a used truck with an L track already installed on the inside of the bed rails. Wasn’t really sure what it was for, but with these rings, I now have several more tie downs. And bonus is that they are adjustable and can be moved. Could not be happier with this product.
