3×1 In-Line Cordelette Load Sharing Anchor

The 3×1 In-Line Cordelette LSA is designed to distribute load evenly across three anchor points aligned in a straight line. This configuration is particularly useful when dealing with multiple anchor points that are not equally strong or when the direction of the anticipated load is straightforward.

Key Components:

  • Cordelette: A loop of high-strength cord, typically 6-7mm in diameter and about 5-7 meters in length, used to connect multiple anchor points.

  • Anchor Points: Three individual anchors (natural or artificial) aligned in a straight line relative to the expected load direction.Rigging Lab Academy+3Wikipedia+3Wikipedia+3

Setup Steps:

  1. Identify Anchor Points: Select three solid anchor points that are approximately in line with the anticipated load direction.

  2. Attach Cordelette: Wrap the cordelette around each anchor point, forming loops that will converge at a central point.Alpinesavvy

  3. Create Master Point: Bring the loops together and tie an overhand or figure-eight knot to form a master point where the load will be attached.

  4. Equalization: Adjust the lengths of the cordelette segments between the anchors and the master point to ensure that the load is evenly distributed among all three anchors.

Advantages:

  • Load Distribution: By equalizing the tension among the three anchor points, the system shares the load, reducing the force on any single anchor.

  • Redundancy: The use of multiple anchors provides a backup in case one anchor fails.

  • Versatility: This setup can be adapted to various terrains and anchor configurations.

Considerations:

  • Angle Between Anchors: Keep the angles between the anchor legs as small as practical (ideally less than 60 degrees) to minimize the force on each anchor.

  • Extension: Be aware that if one anchor fails, the system may extend, potentially causing shock loading. To mitigate this, knots or limiting devices can be added to the cordelette legs.

  • Inspection: Regularly inspect all components of the anchor system for wear, damage, or shifting during use.
