ONE DEVICE POSITION. MULTIPLE CONDUIT-ENTRY OPTIONS.

Single-gang weatherproof boxes provide a compact enclosure format for one device position while offering several conduit-entry arrangements. The grouped catalog options make it easier to select the required number and location of openings without treating every hole pattern as a separate product page.

The aluminum body uses a powder-coated finish, and the catalog structure distinguishes ordinary patterns from side-opening versions. Models with side openings carry the X suffix, helping buyers identify the required configuration during selection and ordering.

  • Single-gang format: Provides a compact enclosure layout for one device position.
  • Multiple hole patterns: Offers several conduit-entry arrangements within one product family.
  • Aluminum construction: Keeps the enclosure body comparatively lightweight.
  • Clear model identification: Uses the X suffix to distinguish side-opening configurations.
