Key benefits Reliable elastic performance: stores energy when stretched and returns to its original length after the force is removed, maintaining consistent tension. Durable and long lasting: made from spring steel for repeated use and sustained stability in demanding applications. Easy to attach: double hook ends enable quick, secure connections to pull ropes, tension bands, and other mounting points. Compact and versatile: small overall footprint with a wire diameter of 1.5 mm, an outer diameter of 12 mm, and a length of 40 mm, suitable for tight spaces. Specifications Wire diameter: 1.5 mm Outer diameter: 12 mm length: 40 mm Material: spring steel Configuration: double hook ends for convenient connections to hooks, holes, ropes, and bands Performance and compatibility Elastic ensures reliable tension without manual reset after each actuation. Suitable for systems requiring quick and repeatable engagement and release of tension. Hooks on both ends support versatile attachment to rope, band and other fixture holes without specialized hardware. Design notes The double hook design provides straightforward integration into existing assemblies, reducing setup time and simplifying maintenance. Practical use scenarios Household or workshop rope tensioning: install in a small ropedriven mechanism to maintain steady tension and allow easy adjustment. Fitness equipment and portable setups: connect tension bands or resistance bands to create adjustable, secure connections that to rest after use. Small machinery or cabinet applications: use in compact systems where a spring is needed to keep components in alignment or to provide a controlled retraction force.
