I've been using this type of securing strap for a long time. The original I used went out of business and they used plastic D rings. Green Chile utilizes metal D rings, less like to weaken over time.
All the extra tie-foen points 8 could ask for - And they're secure!
Double D Ring Loop
I purchased more after using the strapping system to ride to the U.P. of Michigan. They worked great. No slippage.
