From the Technical Data Sheet

  • Enables airflow to eliminate bundling limitations. NEC 310.15(C)(1)(d).
  • Rigid connection to structure eliminates the need to tie off to the ceiling grid below. NEC 300.11(A).
  • Finish: zinc plated.
  • Support spacing governed by the applicable local building code.
  • Dry locations only, per the listing.
  • Rated load carries a minimum 4:1 factor of safety on ultimate tested capacity per ICC-ES LC1041 and UL 2239.
  • The rated load applies to the support assembly only; the attachment to structure is evaluated separately (Section 01).
  • Drawings not to scale.
