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 rigorous testing, above and beyond standard CSA and UL 360 standards. Liquatite products that meet CSA Annex A “Heavy-Duty” include Types LA, ZHLA, CBLA and CSA. Only conduit trade sizes ½” through 4” qualify for the (HD) “Heavy-Duty” designation.
