Step-by-Step Installation for Flawless Results
- Drill or punch a precise 1.14" hole in your enclosure wall.
- Slide the cable through the fitting body and compression nut.
- Insert the body into the hole from the inside, then thread the nut from outside and hand-tighten.
- Use a wrench to snug it up (torque per specs to avoid over-compression).
- Test the seal with a water spray or submersion check before powering up.
This straightforward process cuts install time by up to 50% compared to traditional glands, letting your team move faster without sacrificing safety.
