MORE DEVICE SPACE WITH CLEARLY GROUPED ENTRY PATTERNS

Double- and triple-gang weatherproof boxes provide additional wiring and device space for installations that require more than a single-gang enclosure. The catalog range groups the available hole patterns by gang size, opening count, and entry arrangement so buyers can compare configurations on one page.

The powder-coated aluminum construction keeps the larger enclosure formats manageable during installation. Ordinary models and side-opening versions remain clearly separated, with the X suffix identifying catalog numbers that include side openings.

  • Multi-gang capacity: Supports double- and triple-gang device and wiring arrangements.
  • Grouped configurations: Organizes different hole counts and entry patterns for easier comparison.
  • Powder-coated aluminum: Combines a lightweight metal body with a confirmed applied finish.
  • Consistent suffix rule: Identifies side-opening models with an X at the end of the catalog number.
