Target, yes, Mark's OP refers to using a tow hook loop on the extension, not a ring.
By the way, I found 50 ft. of "550 Paracord" (3.18mm dia, 150lb working load) at Lowe's for $6.70. This is probably pretty close to what Mark uses for his extension. This size paracord gives plenty of clearance for tow hooks. It ties into a nice secure tow hook loop using a Yosemite Bowline knot. Be sure
you can pull hard on either side of the loop cord and not
have the loop slip into a smaller one. The Yosemite Bowline knot is easy to tie wrong if you've had too many beers.
