Excellent Coupling for Electricians

The material is highly durable and resistant to wear and tear, ensuring a longer lifespan. The only minor downside is that it may require additional tools for installation, but the end result is well worth it. Overall a great product for electricians looking for reliable…

Easily reusable EMT conduit

Fully cast zinc connectors are best used when living in a humid climate. Some steel connectors are galvanized and others are bare steel. The EMT is not intended for use in adverse weather conditions, but under the eaves, on the porch it is fine, but the humid or coastal climate will give it problems. In such situations, cast zinc fittings are worth the extra cost. I've used EMT light wall tubing in construction and in numerous businesses I own and rent for decades, but it wasn't until I retired

Pros
  • Electrical
Cons
  • Long lead time
