Bow Setup & Tuning – How to Tie a D-Loop

In Part 4 of our bow build we look at something that every bowhunter needs to know – how to tie a d-loop.  The knots look a little intimidating at first, but once you do it a couple of times it becomes natural.  You’ll also learn why not every d-loop should be the same length, as well as a few things to look out for as your putting a new d-loop on your bow.

Additionally, here is a step-by-step pictorial of the tying process…

How to Tie a D-Loop - Step 1

Step 1 – Start with one end of your loop material overlapping the string.

How to Tie a D-Loop - Step 2

Step 2 – Wrap the loop material around the string, then back over the starting end of your loop material.

How to Tie a D-Loop - Step 3

Step 3 – Wrap the material around the bow string once again, then come up and through the “loop” that you formed with your d-loop material.

How to Tie a D-Loop - Step 4

Step 4 – Cinch this first knot down, being sure that the starting end of your loop material is seated tightly within the knot.  (See the plier trick in the video!)

How to Tie a D-Loop - Step 5

Step 5 – Form the “D” of your d-loop by arching the loop material over the string.  Be sure that the “legs” of your arch are on opposite (near/far) sides of the bow’s string!

How to Tie a D-Loop - Step 6

Step 6 – Wrap your loop material around the bow string, bringing it back through the “arch” or “D” of your d-loop.

How to Tie a D-Loop - Step 7

Step 7 – Bring the loop material back across the bow string, then come up through the loop that you just formed.

How to Tie a D-Loop - Step 8

Step 8 – Pull the end of your loop material, cinching the 2nd knot tight, and adjusting the size of the main loop.  (Keep in mind that your d-loop will stretch and increase in size!)

How to Tie a D-Loop - Step 9

Step 9 – Cut the excess loop material, leaving about a 3/8″ tail remaining.

How to Tie a D-Loop - Step 10

Step 10 – Fuzz the tail of your loop material, and then slowly melt it with a lighter.  Once the fray is melted into a nice ball, smash it flat against your lighter.

How to Tie a D-Loop - Step 11

Step 11 – Use a pair of needle-nose pliers to stretch the d-loop and set the knots.  It is perfectly safe to use quite a bit of force in this step.

That’s it!  Now it is time to shoot.

Let me know if you have any questions…

    Excellent tips Mark. Most pro shops I know charge $10-15 just to do this when it’s so simple to do at home!

    • SoleAdventure

      Thanks, Al. Not only will it save you some coin, but it could also save a hunt if you have a loop fail at the wrong time.

    Hey Mark,

    I have a quick question about D-loops. I have been looking into trying out a thumb release and notice that some models have twisting heads and some don’t. For the releases that don’t have twisting heads (like a Spot Hogg Whipper Snapper and your Scott Exxus) would I need to have a different D-Loop so I can shoot with the thumb button facing down (palm facing out instead of palm facing down). I imagine there would be some twist in the D-Loop, is this something you’ve experienced before?

    • SoleAdventure

      Great question, Kurtis. The twist that your place in your release hand to reach a comfortable anchor point can introduce some twist in your d-loop, but that doesn’t necessarily translate into torque on the bow’s string. What you want to watch out for are really small d-loops and incredibly stiff loop materials; that combination won’t have enough “give” to twist without affecting the bow string. I have used quite a bit of BCY’s loop material (it’s the standard in most places), and haven’t had any problems.

      • Kurtis Baus

        What would a “really small” loop measure? I don’t have my bow with me at the moment and don’t know what the measure from string to end of loop is.

        • SoleAdventure

          There’s no one magic number to look for. It depends on the size of the release jaws, as well as how much twist/torque you happen to put on the loop at anchor. I’ve seen guys that make their loops so small that there’s barely enough room to clip/hook the release behind the nock – and those are the small loops that I would start to look closely at for string torque.

    Now I know. Thanks Mark!

  • Wesley Levy

    Thanks for the tips! you’re right about the fact that once you do it a few times, it becomes second nature

    Hi, great tutorial. I’ve been battling a problem this summer that snuck up on. Over the summer, I started shooting low and couldn’t determine why. Then, after talking with my pro shop, discovered that, unbeknownst to me, he switched D loop material and as a result, the D loop started slowly moving up on my string raising my knocking point. My previous set up had the other D loop material and I never had that problem before. Can you recommend a D loop material that tightens up so much it will not move?

    Thanks, Shane
