Buying Guide
What to consider when selecting a non metallic sheathed cable connector:
- Size compatibility: match connector diameter to cable gauge (3/4″, 1″, etc.).
- KO vs snap/clamp style: KO offers knockouts in electrical boxes; snap/clamp types suit confined spaces.
- Material and finish: die-cast zinc or plastic affects durability and ease of installation.
- Pack count and project scope: choose packs that align with your project size to minimize waste.
- Environmental use: ensure moisture resistance if the location is damp or outdoors.
