Technical Specifications

This fixture mounting system features a 4" octagon box configuration with 15.5 cubic inches of wire capacity, constructed from durable steel materials. The adjustable bar extends to 16" for standard joist spacing, while integrated 1-1/2" NM cable clamps provide secure non-metallic cable management. The assembly measures 4" wide by 1.5" high by 16" long and weighs 1.02 pounds. The system is fixture-rated for ceiling fan and heavy lighting applications, complying with NEC/CEC standards for structural support and electrical safety.

Installation Process

  1. Position adjustable bar between ceiling joists at desired fixture location
  2. Adjust bar length to achieve secure fit against joist faces
  3. Secure bar to joists using appropriate fasteners for joist material
  4. Route NM cable through integrated 1-1/2" cable clamps
  5. Make electrical connections within the 4" octagon box
  6. Install fixture mounting hardware and connect fixture per manufacturer instructions

Applications

Perfect for:

  • Residential Ceiling Fans - New construction and retrofit ceiling fan installations
  • Heavy Lighting Fixtures - Chandeliers, pendant lights, and substantial ceiling-mounted luminaires
  • Remodel Projects - Adding fixture support in existing construction without ceiling access
  • Light Commercial Applications - Office buildings, retail spaces, and small commercial facilities
  • Multi-Family Housing - Apartment complexes, condominiums, and townhome developments
  • Educational Facilities - Classrooms, libraries, and administrative areas requiring fixture mounting
  • Healthcare Facilities - Patient rooms, waiting areas, and administrative spaces
  • Hospitality Projects - Hotels, restaurants, and entertainment venues

Octagon Box System Benefits

Octagon electrical boxes provide superior fixture mounting capabilities compared to standard rectangular boxes, offering multiple mounting points and enhanced structural support. The octagonal shape distributes fixture weight more evenly, reducing stress concentrations that can lead to box failure. This design is particularly important for ceiling fan installations where dynamic loads and vibration require robust mounting systems.

Why Choose Integrated NM Cable Management?

The built-in 1-1/2" NM cable clamps eliminate the need for separate cable connectors, reducing installation time and ensuring code-compliant cable securing. This integrated approach provides cleaner installations with fewer components while maintaining the cable strain relief required by electrical codes. The steel construction ensures long-term reliability in demanding fixture support applications where Eaton Crouse-Hinds quality makes the difference.
