How to Choose the Right Coupler for Your Activity

Selecting the best coupler shouldn’t be overwhelming. Consider the following factors while making your choice:

1. Activity Type

Are you climbing, training, or doing both? Climbers may prefer screw-lock or auto-lock couplers for security, while fitness enthusiasts might lean towards quick-draw couplers for easier transitions.

  • Follow Weight Limits: Each coupler has a maximum load capacity, so never exceed it.
  • Secure the Lock: Always double-check that screw-lock or auto-lock mechanisms are properly engaged before use.
  • Practice Proper Placement: Ensure the coupler is positioned correctly to prevent cross-loading (i.e., uneven stress distribution).
  • Keep it Clean: Dirt and debris can interfere with locking mechanisms, so regular cleaning is essential.
