How strong is the webbing material that holds the D-ring on each corner ?

Decent. It has held up all summer with no problems, but we haven't had a really windy day this summer.

There is plenty of velcro in place to keep things secure but keep in mind that this is for low angle work only. Most of the force is on the buckle itself, with very little on the velcro. Edit: If you're talking about the velcro that keeps the V-Ring in place it has no use while on rope. Purely cosmetic.

More than strong enough. This holder snatches the knives right out of your hand and doesn't want to let go. In fact you have to rotate the knife into its back edge to break the hold on it and remove it.

I have no idea. It's pretty sturdy. The stringing and adjustments seem pretty straight-forward. I wouldn't be concerned unless I was letting a few Silverback gorillas play with it.

Maybe an inch. I use it for both a lax bounce back - tighten with bungee cords - and a golf hitting net.

I would think it would tell you that in Specs section of the product. That being said, it is quite flexible and can be pulled as tight as you want it (IMHO) by looping the bungee cords.

It seems to be pretty strong. I stretched it enough to get a good, tight wrap without it breaking. I don't know just how much it would take, but at least I didn't have a problem with it breaking.

It is strong, but it's still aluminum, I suppose if you didn't use too much force. I think I'd just buy a boat hook.

It seems to be plenty strong, and is plastic. I used it on my hardhat for hours and it stayed in place.

You could use two d-rings sewn to one end and tighten that way, like a webbing belt. The webbing is fairly slick, I've never tried to use a d-ring with this, so it may come loose. http://www.amazon.com/gp/aw/d/B004BP1WNE/ref=mp_s_a_1_4?qid=1415130511&sr;=8-4π=SL75

None whatsoever. It is very strong and pliable. Works well. I use a harness as opposed to a collar.

As the magnets are working through glass(I think that is what you mean when you say both sides) and also dealing with wind and the elements, I would suggest nothing thinner then a 1/4" thick. You would probably get more strength with a block magnet then a disc if the rectangular shape would work for you.

I have stretched it over huge heavy loads of bagged leaves in the bed of my pickup truck and it has not torn. It seems to be made of quality bungee cord material. Let me suggest though that one might do well to remove 12 of the 16 hooks as all you really need are the corner hooks. The excess hooks, if left on, present a huge problem with the whole net getting snarled up like a Gordian knot. I have stretched this net from the front tie downs, up and over bags that were 2' higher than the cab and then connected to the bottom of the rear bumper with no problems. But, of course, I lash a few pieces of 550 nylon line over the top to prevent shifting and to secure the load more snugly.

strong enough for a 220lb guy to use it as a hammock..so about 55lb per each corner tie out

The straps are really well built, and can handle a lot of weight. The stitching through the body is also really solid and will hold up well. The only possible weak point I see are the attachment points of the D-rings. They're stitched and riveted on, but depending on your strap configuration it sometimes pulls them at odd angles and over time they could start to rip away. But honestly I have mine loaded with school books and nothing looks like it's going to break or tear anytime soon.

I purchased the 3/8" version and it holds my rope light firmly in place. My rope light is outdoors subject to heavy winds at times and i have had no issues.

It seems really strong to me. I clip it to my clogs and my sneakers. It has never come off and doesn't seem any looser because of use.
