Anchor Fundamentals
A bomber anchor is your lifeline in trad climbing.
ERNEST Principles
Every anchor should be:
- Equalized: Load distributed across pieces
- Redundant: Multiple independent pieces
- No Extension: Won't shock-load if piece fails
- Efficient: Quick to build, minimal gear
- Solid: Bomber individual placements
- Timely: Built quickly but carefully
Minimum Standards
Number of Pieces
- Minimum 2: For top-rope
- Preferred 3: For climbing
- Consider 4+: In marginal rock or critical situations
Quality
- Each piece should hold full load independently
- Combine marginal pieces to create bomber anchor
- Never rely on single marginal piece
Anchor Components
Protection Pieces
- Cams, nuts, or bolts
- Natural protection (trees, rock features)
- Fixed gear (test thoroughly)
Connecting Material
- Cordelette (7mm, 18-20')
- Static rope
- Dyneema slings
- Quad setup
Master Point
- Where rope clips in
- Should be easily accessible
- Usually locking carabiner(s)
Direction of Load
Consider:
- Downward: Most anchors
- Upward: Overhanging situations
- Outward: Traverse starts
- Multi-directional: Variable loading
Common Anchor Configurations
We'll cover specific setups in the next article:
- Cordelette anchors
- Quad/Triquad
- Sliding-X
- Pre-equalized
Critical Checks
Before using anchor:
- ✓ Each piece bomber individually?
- ✓ Load equalized?
- ✓ System redundant?
- ✓ No extension if piece fails?
- ✓ Master point accessible?
- ✓ Direction of load correct?
Partner Check
Always have partner verify:
- Individual placements
- Rigging configuration
- Carabiner gates
- System redundancy
