Slider keeper. Use it to keep the slider down at the bottom of the risers and out of the way for swooping.

That is a slider holder to hold his slider behind his head. Most of the one's I've seen are attached to your jumpsuit and not your rig.

The Mullins kids have them on their rigs now. They are wrapped around the reserve pin cover so that in a cutaway the keeper just slides off the pin cover with the slider.

Well, that's the theory anyway.

I'm not so sure it has been tested and proven it actually works as well as most people hope it will.

Look at where the force will actually be applied -- will that provide enough leverage to open the reserve flap by only cutting away? If not, will the main depart fast enough to clear the reserve when it deploys?

Well, Hooknswoop's tests proved that the velcro wouldn't hold a canopy to the velcro keepers anyways, so I would think it would be a non-issue.

However, obviously, I am not a rigger and I've been known to be wrong many times.

Right, a small patch of Velcro that was recently mated will not support a jumper's weight, or more if they are pulling any "G's". I tested this exact scenario with an intentional cutaway.

Also, most cutaways happen before the slider is stowed. Not all, but most.

Can you define "a small patch of Velcro"?

Take a look at the photo in the original post in this thread. I dunno, looks like it's maybe five or six inches of one inch wide material to me. If that's three inches of male and three inches of female, that might be one thing, but if it's six inches of male and six inches of female -- holy smokes -- I'd wager that would hold quite a bit.

4 inches by 1 inch of pile/loop and 1 inche by 1 inch of hook. I also use 2 squares of 1 inch by 1 inch to make the loop that goes aroung the reserve flap. Gives it another way to release, for a total of 3.

Guys,

The men in black at raeford have been using this type of slider stow for a while. Call up Skymonkey1 or Skymonkey2 for details.

I don't know about whether this theory has been tested, either, but I was told the peak force for an RSL to pull the reserve pin if a worst-case ring alignment configuration (if the jumper is head-down during the cutaway and the ring at the end of the RSL slides all the way up against the static ring) can be 600 pounds.

On the one hand I doubt this is a realistic amount to get from one riser of a cutaway canopy that isn't held by both risers anymore.

On the other hand this assertion is something that may have some testing behind it. There may be design and testing data indicating just how hard a cutaway canopy really can pull on the RSL / risers. If it's some huge figure, we can assume several square inches of velcro here or there won't make a difference.

So, who knows about tested RSL pull strengths?

why not just make one on your jumpsuit? For the times when youre not jumping your suit just stow it without a keeper behind your head. Why fucking with shit near your reserve? That seems stupid to me.

The concept is that it gives the main one more chance to depart.

If it were attached to your jumpsuit and the velco -didn't- separate, then you'd really feel stupid for awhile -- maybe the rest of your life.

Well, considering that the only actual tests that have been run that I know of were done by Hook with the velcro patch on the suit, and it was shown to work, I'll stick with that.

If you pull that little tab really really hard in freefall you fall slower.

Naw, not really.

Actually it inflates a rubber raft... you know, for water landings.

Do you honestly think your slider holder is that strong? You might be better off just not bringing the slider past the links then? Problem solved.

No, but limiting risk is a good idea.

That is when it is used, to keeop the slider down at the 3-rings. It wouldn't work if the slider wasn't pulled down past the links.
