In the world of precision archery, your D-loop is the critical link between your release and your bowstring. A poorly installed loop can lead to inconsistent anchor points, peep rotation, or even dangerous equipment failure. To help you achieve a competition-grade setup, Pine Ridge Archery has provided a definitive guide on how to install the Nitro String Loop.
Follow these professional steps to ensure your loop is secure, centered, and built to last.
1. Preparation and Leveling
Before you ever touch the string material, you must ensure your baseline is correct. Start by placing your bow in a high-quality bow vise. Use a string level to ensure the bow is perfectly vertical. Next, snap an arrow onto the string and use an arrow level to find your 90-degree horizontal plane. This ensures that when you install the loop, your nocking point is perfectly tuned to your rest.
2. Preparing the Nitro Material and the Top Knot
Nitro String Loop material is known for its durability, but it requires proper "mushrooming" to stay secure. Take one end of the material and fray the fibers slightly. Apply light heat with a lighter until the end melts into a rounded, flared "mushroom" shape. This flare acts as a safety stopper that prevents the cord from pulling through the knot under the high tension of a compound bow. Once cooled, tie your first knot above your nock point and pull it firmly to set the seat.
3. Centering and Alignment
Precision is a game of millimeters. Before you fully tighten the top knot with tools, re-check your levels. Ensure the loop material is positioned exactly where the arrow sits level. It is much easier to make micro-adjustments now than after the material has been stretched.
4. The Bottom Knot: Preventing Peep Rotation
This is the step where most amateurs make a mistake. When tying the bottom knot, you must ensure it is tied in the opposite direction of the top knot. By alternating the direction of the knots, the torque created by the release is neutralized. This prevents the string from twisting during the draw, which is the primary cause of frustrating peep sight rotation.
5. Finishing and Stretching
Once the knots are positioned, cut the excess material, leaving enough to fray and mushroom the bottom end just like the top. Finally, the most important step for longevity is the "set." Insert a pair of D-loop pliers or heavy-duty needle-nose pliers into the loop and apply significant pressure to stretch the knots tight. This ensures the loop won't move or "creep" after you start shooting.
By following this Pine Ridge Archery method, you’ll enjoy a rock-solid anchor point and a peep sight that comes up straight every single time.
