A Primer on the Installation of Couplers

Anodized aluminum reverse-threaded couplers
designed for use with any of the many innerduct
or PE conduit types.

- Air-tight for pressurized cable propulsion systems
- Reverse threaded
- Designed for smoothwall, ribbed, or corrugated duct

1. Use an innerduct cutting tool to cut the ends of the innerduct squarely. The cut at the end of the innerduct should be at a 90 degree angle to the innerduct wall.

2. Shove both ends of the innerduct into the coupler so that the innerduct wall is as parallel as possible to the ridges on the outside wall of the coupler.

3. Turn the coupler in the direction of the arrow on the coupler label using a strap wrench, vice grip, or similar tool.

4. Tighten to 100~150 foot-pounds of torque
