The key to getting the most out of your new Gstrings is learning how to adjust the 3D-Sling to produce the various grip positions: edge, jug, crimp, sloper, pinch (horizontal and vertical), mantle and undercling. It’s easy and quick to change from one grip position to another once you understand the basic principles and practice it a few times. It easiest to remove the Gstring from whatever they’re hanging from, make the adjustment, then re-hang. It’s possible to adjust them while they hanging from their mounts but it’s a bit clumsy and you need a chair, step-stool, or short ladder to do it.

The photo sequence below illustrates the simple process of adjusting the 3D-Sling by loosening the Prusik knot and sliding the hang loop along the sling. This allows you to set the different grip positions and fine tune the angle (difficulty) of each position... more

Classic


Locate the locking loop of the Prusik knot on the hang loop.

   

Loosen it by flipping it back with your thumb.

   

Insert three fingers and cradle the loosened Prusik knot...and

   

...pull up and slide the knot forward or backward along the sling to the new position.


 
 
 

Press the locking loop back in place and pull to tighten the Prusik knot.
                

                 

Make sure to keep the Prusik knot centered in order to keep the Gstring hanging straight. 
  

           

If needed, the overhand knot can be loosened and retied to make minor adjustments in the hanging height of the Gstrings.

 

Periodically check the cords for wear by the holes where it goes into the hold. Also check the knots inside of crimper to make sure they’re secure.


The “fine print”

  1. Gstrings are designed for exercise only and should only be used as described in this website. Each Gstring should be suspended so each of the four cords of the sling holds an equal amount of the climber’s weight. Using a single Gstring repeatedly with only two of the four cords holding over 200 lbs can lead to metal fatigue and possible failure of the hold.  The vertical pinch grip is an exception to this. In this position it is designed to hold the climber’s weight using just two of the four cords for support. It is the sole responsibility of the user to follow these instructions.

  2. Climbing-related activities are inherently dangerous and the risk of death or serious injury can never be completely eliminated. It is the climber’s responsibility to seek competent climbing instruction and then make his/her own choices regarding acceptable risk.




 

How to adjust for different grip positions

When first receiving your Gstrings, after travel, or after adjusting the angle of the grips, make sure the spreader bar is locked down all the way against the bottom of the hold and that the cords of the 3D-sling are pulled through the holes. Because the 3D-Sling on the Classics are stiff, they can push up through the holes and pop the spreader bar up.

Also, make sure that all four cords of the 3D-Sling are of equal length so they equally support your weight. If they are unequal, pop the cord-lock tube up and shorten the longer leg by pulling cord slightly through the tube, then re-lock the cord by pushing the tube down against the bottom of the grip.
