- Designed for durability and reliability, the sleeves are constructed with an inner EVA meltable adhesive tube and a polyolefin heat shrink outer tube 
- Strength member within the sleeve is made of tempered stainless steel with rounded and polished edges 
- Entire assembly is heat bonded to ensure that all members maintain perfect alignment during shipping, handling and the shrinking process for the best in optical fiber protection 
- Does not affect the characteristics of the fiber light guide 
- Protect the fiber splice point, improving its mechanical strength, reduce damage to the fiber installation 
- Heat shrinkable tube ends shrink, make it transparent tube fiber optic splice status at a glance 
- Strengthening core using stainless steel needle, grinding both ends, to avoid breaking the fiber
