Liquatite® Conduit Types LA, ZHLA, and CBLA now CSA Certified “Heavy-Duty”

ELECTRI-FLEX COMPANY, Roselle, IL, announces product Types LA, ZHLA, and CBLA now conform to C22.2 No. 56-17 Annex A “Heavy-Duty” for CSA Certification. The “Heavy-Duty” Annex requires liquidtight flexible metal conduit to pass additional tension, cold flexibility, connector compatibility, and crush tests.

The Heavy-Duty Difference means that these conduit types passed vigorous testing, above and beyond standard CSA and UL 360 standards.

  • Tension – Withstands greater tension force.
    • Tested to 500 lbs. which is a 66% greater force applied versus standard CSA and UL testing.
  • Cold Flexibility – Superior flexibility in cold temperatures.
    • Placed in a freezer for 4 hours, 300% longer cold exposure and then wrapped around a smaller mandrel with a 30-37% tighter bend radius.
  • Connector Compatibility – Stronger connector attachment.
    • Pulling force of 350 lbs., which is 133% greater force applied versus UL testing.
  • Crush – Excellent crush strength.
    • Meets the same tough standards as UL, 1,500 – 2,000 lbs. depending on conduit diameter.
