Liquatite® Conduit Types LA, ZHLA, CBLA, and CSA are CSA Certified “Heavy-Duty”
Electri-Flex product Types LA, ZHLA, CBLA, and CSA 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 CSA Certified 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.
Only conduit trade sizes ½” through 4” qualify for the (HD) “Heavy-Duty” designation.
