Buying Guide
When selecting 3/4″ EMT LB conduit bodies, consider the environment, installation method, and maintenance plan. Construction material affects weight and corrosion resistance; aluminum LB bodies are lighter and corrosion-resistant, while zinc alloy parts can offer higher strength in certain environments. Key factors include:
- Type and function: LB conduit bodies help with loops, pulls, and access for maintenance. Confirm the LB designation and ensure the body supports 3/4″ EMT conduit.
- Cover and gasket: A reliable gasket prevents moisture and dust ingress. Look for units including a gasket and a securely fastened cover.
- Installation method: Set screw vs. threaded connections impact ease of service. Choose based on anticipated maintenance frequency.
- Material: Aluminum is lightweight and corrosion-resistant; zinc alloy offers strength for demanding environments.
- Location and code: Use dry-location-rated LB conduit bodies where appropriate and confirm local code compliance for electrical installations.
For projects requiring multiple access points, consider multi-pack options to reduce total hardware handling and ensure consistent installation quality. Always follow manufacturer guidelines for torque, cover seating, and gasket compatibility to maintain conduit integrity over time.
