Replacing the Sling and Hang Loop (Classics)

(replacing the 3D-Sling on PROs)

Needed:

  1. 54” of 5mm cord for each 3D-Sling (a total of 9’ for both grips).

  2. 28” of 4mm or 5mm flexible accessory cord for each hang loop (a total of 56”). 4mm cord will provide more holding friction, though it will be slightly harder to release the Prusik knot each time when adjusting.

  3. (Note: Any 5mm climbing accessory cord can be used for cord replacement. However, the original 3D-Sling uses two different types of cords: A stiff spun polyester (similar to Spectra) with a high friction sheath is used for the sling so the Gstring can easily be hung over the head and will hold its position; A flexible but static polyester double braided sheath and polyester core which is more flexible and smooth is used for the hang loop, allowing easy sliding and adjustment along the sling. If you desire an original 3D-Sling and hang loop replacement set, you can order them ordered here.

Steps for replacing one piece 3D-Sling

  1. 1)Study the old 3D-Sling carefully before removing it so that you understand how it is threaded and attached to the Gstring.

  2. 2)Cut off the old sling with knife or scissors by cutting close to the crimper hole.

  3. 3)Remove knots from inside the crimper hole. If they don’t come out easily, use a dowel, pencil, or chopstick to push them out.

  4. 4)Take off the cord-lock tube and save to re-use.

  5. 5)Make sure the ends of all new cords are burned so they won’t unravel.

  6. 6)Thread cord through the cord-lock tube and center the cord-lock tube so that each leg of the sling is equal, then fold each at right angles to the cord-lock tube.

  7. 7)Take one end of the cord and pass through the hollow in bottom of the “G” and thread it from the inside out and pull through until the cord-lock tube is even with the hole.

  8. 8)Take the other free end of the cord and thread through the other hole in the bottom of the “G” from the inside out. Pull tight so the cord lock tube is seated firmly against the bottom of the grip.

  9. 9)Take a free end of the cord and cross it over the back of the sloper to the crimper hole on the opposite side of the grip and thread through the crimper hole going from the outside in and out the end.

  10. 10)Pull out approximate 6 inches

  11. 11)Take the end of the other cord and do the same but crossing to the hole in the other side of the crimper.  The two legs of the sling should cross and form an “X” on the back of the sloper.

  12. 12)Tie an overhand knot in each end and tighten the knot so there is 1/4”-1/2” of tail.

  13. 13)Stick each knot inside the hollow of the crimper. It may take some force to get the knot inside the hollow of the crimper.

  14. 14)Each strand of the sling should cross from one side of the grip to the other forming an “X”.

  15. 15)Pull as hard as possible on each cord where it goes into the crimper in order to tighten and “set” the knots.

  16. 16)Check the sling to make sure that each loop is exactly equal in length. If they are not equal, adjust them until they are. This may take of bit of trial and error. Lift up the cord-lock tube and pull a small amount of cord from the long side through the tube to the other side. Then lock the cord-lock tube back down by pulling on each cord where it emerges from the hole in the jug while pressing on the cord-lock tube until it is firmly against the bottom of the grip. The cord-lock tube helps lock the sling in place so one side does not become longer than the other while using. It’s extremely important that the length of each side of the 3D-Sling are equal and balanced or it will be difficult for the grip to hold it’s position and for your weight won’t be evenly distributed among the sling cords of each grip.

  17. 17)Retie the hang loop around both sling cords using a Prusik knot

  18. 18)After hanging and using for a bit, recheck to see if both sides of the cord are still equal. As the knots tighten they can get out of balance. If they are out of balance after using for awhile, repeat step 16

Alternate method for re-slinging Gstrings - two piece sling, (no cord-lock tube)

Instead of using one long continuous piece of cord for the 3D-Sling and the spreader bar, you can cut the cord into two equal pieces (about 27-29” each). The disadvantage is that there are twice as many knots which can tighten or loosen and cause the length of the cords to become unequal. It’s also harder to equalize the two slings once the knots have been weighted.

  1. 1)Remove old sling as described above (steps 1-3).

  2. 2)Burn all ends of the two cords so they will not unravel.

  3. 3)Thread one end of each cord through the holes in the crimper and pull out 6”-8” of the cord

  4. 4)Tie an overhand knot in the end leaving only 3/8” - 1/2” of tail. Tighten the knot and then pull/push it back inside the hollow of the crimper. (The stiff cord and tight location inside the crimper will not allow it to loosen once it’s tightened and set in place.)

  5. 5)Take the free end of each cord and cross over the back of the sloper, crossing the cords to the hole on the bottom of the “G” on the opposite side of the grip. Thread through the jug hole going from the outside in.

  6. 6)Pull 6”-8” through each hole and out the side, then tie another overhand knot in each cord leaving 1/2” of tail.

  7. 7)Tighten the knot and pull the slack back through so that the knot is tight against the bottom of the inside of the “G”.

  8. 8)Test to see if each cord is equal in length so that all four “legs” of the cord are equal. The best way to do this is to hang them from where you use them and pull on it with your weight

  9. 9)If one legs is longer undo the overhand knot on that side and shorten appropriately.

  10. 10)Retie the overhand knot and test again for equal lengths of each cord. If still unbalanced repeat steps 5 and 6 until you are satisfied that they are equal.

  11. 11)Retie the hang loop around both sling cords using a Prusik knot.

  12. 12)After hanging and using for a bit, recheck to see if both sides of the cord are still equal. As the knots tighten they can get out of balance. If they’re out of balance after using for awhile, repeat steps 9 and 10
