Experience the stability and performance of our Heat - shrink Seal Closures, a traditional choice for ensuring secure fiber optic connections. These closures come with an Oval Port that serves as the entry point for loop - through cables, providing a smooth and efficient way to integrate cables into your network. During the installation process, heat - shrink tube and other consumables are used to create a tight and durable seal. The heat - shrink technology offers excellent protection against moisture, dust, and mechanical stress, ensuring the long - term reliability of your fiber optic splices. These closures are suitable for applications where a high - level of sealing and protection is required, such as in outdoor aerial or underground installations. While they do require the use of consumables during installation, the end result is a secure and stable fiber optic connection that can withstand the test of time.
