Load Sharing Anchor 2×1 Figure Eight System

Overview

The load sharing anchor 2×1 figure eight system is a streamlined rigging method for sharing load between two anchor points. This setup relies on two figure eight loops tied into a single rope to create a load-sharing system that is simple to rig, easy to inspect, and field-resilient.

It’s most effective when your anchor points are reasonably aligned with your expected load direction, and you need a solution that uses minimal hardware with strong redundancy.

System Purpose

This system is designed to:

• Share load between two independent anchor points

• Use standard rope and figure eight knots to build redundancy

• Provide a clean, compact solution with limited extension risk

• Offer a fixed, non-adjustable load-sharing anchor with equal or near-equal tension distribution

This is a load-sharing system, not dynamic load-distributing. Once tensioned, it remains fixed and does not equalize during movement.

Rigging Instructions

1. Select Your Anchor Points
   Choose two independent, reliable anchors capable of bearing the system’s full load. Ensure they’re aligned in a way that minimizes tension imbalance.

2. Tie Two Figure Eight Loops
   Using a single rope, tie a figure eight on a bight near one end. Repeat the process to form a second loop farther down the line, leaving enough space to align with the second anchor.

3. Clip Each Loop to Its Anchor
   Use locking carabiners to secure each loop to a separate anchor point. Verify that both loops are cleanly dressed and properly oriented for the anticipated load path.

4. Connect the Load
   Attach the main system load (e.g., directional, mainline) to the rope between the two figure eight loops. This center point will now act as your master focal point.

5. Verify Load Distribution
   Adjust rope spacing as needed to ensure both loops are engaged under load. Once tension is applied, both anchors should share the force without slack.

Advantages

• Simple and fast: Uses only rope and basic knots

• No specialized gear required: No pulleys, slings, or adjustables

• Strong redundancy: Both anchors bear load with built-in backup

• Compact and easy to inspect: Clean, visible knot structure with no hidden friction points

Limitations and Considerations

• Fixed load distribution: Not self-equalizing if load shifts

• No shock absorption: Must be rigged tight to avoid slack or extension

• Loop placement matters: Uneven spacing can cause imbalance

• Anchors must be sound: Each must be capable of full load on its own

Use Cases

• Equalizing mainline or belay systems

• Anchoring directionals or edge transitions

• Redundant back-ties in natural or artificial environments

• Rescue systems requiring quick setup with minimal gear

Final Thought

The Two to One Load Sharing Anchor using figure eight loops offers dependable performance with very little gear. It’s a trusted, fast-to-build option when your anchors are in line and your focus is on strength, simplicity, and speed. In skilled hands, it provides solid redundancy and load-sharing without the complexity of more dynamic anchor systems.
