Ensure the box supports the weight of your pendant fixture plus any dynamic load. Most standard boxes support 50 lbs while specialized ones go higher.

Safety Certification
Look for UL ETL or CSA listings to confirm the box meets national electrical codes. These certifications ensure tested safety standards.
Certified boxes reduce risk and ensure compliance with local regulations.
Installation Type
Old work boxes include features like live hinges for retrofits. New construction boxes may need bar hangers or stud mounting.
