HiPerUSA Soft Link

Recommended Posts

Does anyone have instructions on how to make HiPerUSA's HiperLink soft links. I have been wanting to learn how soft links are made, just out of curiousity. I have received instructions regarding the No-sew soft link using Jump Shack's finger trapping method. Was just curious if someone knew how HiPerUSA made their soft links. I tried emailing them about buying some but no repsonse. I will not be using these on canopies or selling them; just for education.
Thanks

Ask Jerry Baumchen because Jerry sent me instructions on how to tie a similar link a few years ago.
I made a set for my 150 and they lasted hundreds of jumps. Now all the suspension lines are due for replacement, but with no signs of significant wear on the soft links.

First photo

Start with a finger trap loop
Notice how the legs separate. It's important.
Exact size depends on application.

Second photo

Now tie a knot across the two separate legs. Another loop is formed.

Third photo

Put the loop from the other end through the newly formed loop,
Then pull this loop over the new stopper knot.

These are very useful, not just for skydivers.
I use them to attach Costco blue tarps to a frame in the back yard.

Great to have a fastener that doesn't need more tying.

Meaning opening and closing don't involve tying and untying any knots.

Thanks Riggerpaul and Jerry! That's what I was looking for. I do have one question. With Jerry's method, there is the no-sew method to lock the finger trap in place. Does the knot way require a method to lock the finger trap or does that knot effectively lock it?
Thanks!

The third photo is completely locked.

I apologize for poor photo quality.

The "first loop" is the loop you see in the first photo.

The first loop goes between the 2 legs and then over the stop knot.

When it is going through between the separate legs, that is "under" the stop knot.

Then the loop goes around the stop knot, which is "over".

Going around the stop knot is what locks it.

The first loop cannot get out from between the separate legs because it would need to go around the stop knot.

That can't happen if the system is under tension.

Make one, you'll see when you have it in your hand.

If the stop knot could somehow come undone, this would fail.

But not likely if it is under tension.

Load it up, and it stays locked.

You need some slack to open it.

Very easy to make, and does not required sewing.

I use them for all sorts of things around the house and yard.

They don't open unexpectedly, and they don't fail if applied properly.

Okay, my back yard isn't life saving.

But these are very handy to have as one of my fastener options.

I do love knowing how to make this sort of stuff! It's fun!

Knots and related thing have always been an interest of mine.

Glad I could help!
