How to Easily Install the Channel on Wrap-around Heat Shrink Sleeves

While installing wrap-around heat shrinkable sleeves—such as our RSBJ series closures—many technicians face difficulties when trying to insert the stainless steel channel into the rail, especially especially when the sleeve is slightly deformed or cold. This step is essential for sealing the sleeve securely around the cable joint, so doing it properly is key to long-term performance.

If you're struggling with this step, you're not alone. In this video guide, we walk you through the proper method to make the channel installation faster, easier, and more reliable.

Common Challenges

Technicians often face these problems:

• The sleeve rail is flattened or deformed

• The material is too stiff in colder environments

• The channel gets stuck halfway through

These techniques are especially useful when using our RSBJ heat shrink closure series, which are widely recognized as reliable alternatives to Raychem/TE/CommScope XAGA 500, 530, and 550 systems.
