Gri Gri Modification (the keeper cord)
« on: April 26, 2009, 11:10:49 pm »
I highly recommend not dropping your Gri Gri.  Not only will it brain some poor hapless sole at the base of your favorite bill wall crag, it will also exponentially increase your suffer factor by the power of two.  Can you imagine actually paying attention while belaying!  You'll never dig out the snacky cakes if you have you have to have your brake hand on the rope. 

Here's a common modification that I've found very useful over the years.  It takes a little while to get use to but is well worth it in the long run.  You'll only need to adapt to having your locker's gate open on the handle side of the Gri Gri so the cord remains on the locker while you load your Gri Gri.

It looks like this



Step one:  Locate the screw on back side of your Gri Gri.



Step two: Remove the screw.



Step three: Pry the plastic bottom down to access a small cavity.



Step four: Drill a very small hole in the plastic and insert a length of 2mm or 3mm cord into the cavity.  Tie a knot or melt the end of the cord to prevent it from coming out.

Step five-ish: Return the plastic cover and replace the screw. 



Step six:  Tie the knot of your choice in end of the cord.  I prefer a bowline (with Yosemite finish) because the loop is more round than a standard overhand/eight on a bight.  The length of you keeper cord should roughly match up with the biner hole of the Gri Gri.

It should end up looking something like this.



I hope this helps because if anything I have now totally forgotten how to use a non modified Gri Gri!

Comprehensive thread, thanks LB.

Coming into the modified Gri realm as the neophyte I am here: How does it work in use?
Say no to limbers, excavators and retro-bolters. No matter how much he smiles.

Is there a similar mod for my iPod?

This is definitely an essential modification.  It doesn't require any metal to be drilled, so if you are one of those people that worries about structural integrity, blah blah blah, don't sweat it.

One thing I recommend doing, when you tie the loop in the keeper cord, make it a smaller loop than what Lunchbox has.  I like it for the loop to be slightly tight on the carabiner, and maybe slightly longer than his, help it stay on the carabiner and not come off.  Which defeats the purpose.

So is this simply a keeper sling? If yes, how is it better than the keeper I girth to one side of the biner hole?

I kinda think of this as a "whatever floats your boat" sort of modification.
I don't drop much stuff. Bad habit, that............ ;-)
Mike, girthed keeper will perform same function.

iPod's require no drilling, simply duct tape it to your skid-lid, right next to your solar recharging panel.

Nice one, Kev. Quite.
Where would we be without duct tape?
And dead cats, of course.................

I'm just suprised that with two Gri Gri mod threads, there hasn't been the standard, "Don't Modify Anything or You'll Die" comment.. yet

No way, man.
this ain't no "school Marm crowd"..................Actually, with sore paws after a few days up, I could see some monkey fumble the gris, but it'd be a minor tragedy.
The gris is a convenience item, after all. Mods are par.

Hey, I'm all for mod's, if it wasn't for people with a little imagination, we'd still be pounding bongs.. (mind you, bongs made some damn nice footholds for us non-super-hero crack master types!)

I guess lunchbox's mod might benefit someone who was not intending to modify their Gri Gri for soloing, but if you use some form of the standard solo mod, you've already created an additional point to clip for anti-fumble insurance.

I've been known to pound bongs..........both kinds.
I like the keeper, but, with my fretfulness about droppin' ANYTHING, I'm pretty death gripped on my shizz.
Ya, know? Good trick for the quiver, though.Thanks, 'Box!
