Why should cord and lock be selected together?
The lock relies on geometry and friction to grip the cord. If the cord is too thin it may slip; if it is too thick, adjustment can become difficult or the lock may not close correctly.
30-SECOND SUMMARY
Quick answer: shock cord and cord locks
- Cord diameter and lock channel geometry must be compatible.
- Surface friction affects both holding force and ease of adjustment.
- The complete assembly should be tested at the real working tension.
Shock cord and cord locks should be selected as one mechanical-textile system. A good cord can perform poorly in an incompatible lock, and a good lock cannot compensate for the wrong cord diameter or surface. This guide is designed to help purchasing, product-development and production teams separate the key technical criteria and move directly to the relevant Bilge Örme product pages.
Measure real cord diameter
Nominal product names are not enough. Measure the actual relaxed cord and evaluate how its diameter changes under tension, especially when passing through a tight lock channel.
Consider surface friction
A smooth braid may slide easily but require more locking force. A textured surface may grip more strongly but increase adjustment friction. The intended user experience should guide the balance.
Check spring force and ergonomics
The cord lock should be operable by the target user while maintaining the necessary hold. Gloves, outdoor use and repeated adjustments can change the ergonomic requirement.
Test the system under load
Use the actual cord, lock, end fitting and attachment geometry. Cycle the system repeatedly and verify holding, release and recovery before production.
TECHNICAL NOTE
A product name alone does not guarantee technical equivalence.
Size, surface, working stretch, recovery, sewing or connection method and the final operating conditions should be evaluated together. When replacing an existing component, a physical sample and real use case provide the strongest reference.

Questions about shock cord and cord locks
Can any cord lock be used with any elastic cord?+
No. Diameter, surface and lock geometry need to be compatible.
Should the cord be tested stretched or relaxed?+
Both conditions matter because diameter and surface behavior can change under tension.
Can Bilge Örme supply cords and accessories together?+
Cord and accessory combinations can be evaluated as a project-specific solution.
