Semi-Inter Tube (SI)

Condition: New product

The Semi-Inter (SI) Interlock tubes are connected firmer than Square Locked (SL) conduits. By interlocking U-shaped stainless steel tape the flexible tube becomes stronger. The Interlock tubes resist high lateral pressure, twisting and pulling, with repeated bending which makes them an ideal solution for protecting optical fibers and light guides.
