All our springs are manufactured from Stainless Steel to BS EN 10151, Grade 1.4310
- The constant force spring is a resilient, rolled up spring.
- Provides a constant and lasting force to the connection
- Manufactured from stainless steel EN standard 1.4310
- The spring can be applied by hand without any tools
- Corrosion resistant
- The sheating needs to be positioned under and on top of the first turn
- In a cable joint, the constant force spring is protected by self fusing insulation tape
