Raco RACO7120-1 Saddle Box For Ceiling Fans
The RACO7120-1 is a 4″ round, non-metallic saddle box designed for ceiling fans and fixtures. It features self-gripping NM/SC wire entry clamps, which provide secure wire management during installation. The box is built to support heavy fixtures, with ratings for up to 70 pounds for a ceiling fan and more for lighting fixtures. This makes it a practical choice for most residential ceiling fan setups where a dedicated fan-rated box is needed.
Key considerations include compatibility with standard joists and the mounting versatility typical of saddle boxes. The integrated clamps reduce the need for additional hardware, simplifying retrofits or new installations. For homeowner projects aiming for a balance of cost, reliability, and straightforward installation, this RACO model offers a well-rounded option.
Westinghouse Fan Master Support Box
The Westinghouse Fan Master is a versatile saddle-style support box with a 16-1/2 cubic inch wire capacity. It accommodates wider joists where a standard saddle box would not fit and can be mounted on either side of a joist without splitting wiring. It supports fans up to 70 pounds and fixtures up to 150 pounds, making it a strong candidate for upgrades or downgrades in ceiling fan installations. Its adaptability and robust weight ratings are advantageous for varied ceiling framing layouts.
Westinghouse Fan Master Jr. Box
The Westinghouse Fan Master Jr. is a smaller sibling in the Fan Master line, designed for standard joist scenarios while still offering a saddle-style installation. It shares the one-sided wiring concept and supports fans up to 70 pounds and lighting fixtures up to 150 pounds. It is a practical option when the joist space is conventional and a full-size Master box would be unnecessary. This model can streamline projects that require a compact but sturdy fan box solution.

It is described as a draft-tight fixture box and is designed for use in ceiling fan and fixture installations where a saddle configuration is needed. The unit prioritizes ease of use and straightforward installation, with the understanding that it is manufactured for standard US electrical work and commonly used in retrofit projects.
4-Inch Round Non-Metallic Ceiling Fan & Fixture Saddle Box
This 4-inch round non-metallic saddle box is a straightforward, saddle-style option that emphasizes domestic manufacturing. It is tailored for ceiling fan and fixture installations with a focus on reliable performance in regular residential settings. While not always matching the weight ratings of heavier-duty boxes, it serves well in standard installations where simplicity and cost-effectiveness are priorities.
Southwire MSBFAN Box
The Southwire MSBFAN is a ceiling fan and light fixture support box featuring depth adjustability and quicker installation compared to nail-on alternatives. Its thicker wall material adds rigidity and stability, contributing to reliable mounting for fans up to 70 pounds and lighting fixtures up to 150 pounds.

The Hubbell-Raco 7120 is a 4″ ceiling fan box with a saddle type design and a depth of 2-5/8″. It is noted for being non-metallic and manufactured in the United States. This box aligns with standard home renovation projects where a reliable saddle box is required to support ceiling fans and fixtures with comfortable installation and robust structural integrity.
Hubbell Raco 936 Retro-Brace Box
The Hubbell RACO 936 Retro-Brace ceiling fan box is designed for old-work installations with adjustable joist spacing. The 1.5-inch deep retro-fit brace can extend from 16 to 24 inches in length. It supports ceiling fans up to 70 pounds or lights up to 110 pounds, making it a strong option for preserving original décor during renovations while maintaining secure mounting.
Buying Guide: Key Purchase Considerations
Box Type And Compatibility
Saddle boxes are ideal where the ceiling joist is accessible and the box can be anchored on the side of the joist. Consider whether you need a standard saddle box, a Jr. version, or a wider-joist compatible design. Match the box diameter (commonly 4 inches) to your fan or fixture mounting requirements.
Weight Capacity
Check the labeled fan and fixture weight limits. Most residential ceiling fans fall under 70 pounds, while some light fixtures can reach 150 pounds. If you anticipate heavier fixtures or future upgrades, choose a model with higher capacity and sturdy mounting hardware.
Wiring And Accessibility
Look for boxes with integrated clamps and simple wire-entry features. Some models support single-side wiring, while others accommodate flexible wiring arrangements on either side of the joist. Ensure the installation method aligns with your existing electrical wiring plan.
Installation Environment
Consider whether you are mounting on standard joists, wider joists, or retro-fitting into older spaces. Old-work designs like retro-brace models can simplify renovations, whereas new-work boxes provide straightforward mounting for fresh installs.
Durability And Material
Non-metallic boxes are common and often easier to work with, while metal boxes provide higher rigidity in demanding environments. Dust, moisture exposure, and long-term vibration can influence material choice, especially in rooms with high humidity or near ceilings with movement.
Brand And Availability
Popular brands like RACO and Westinghouse maintain broad compatibility across many fixtures and fan models. Availability via trusted retailers and compatibility with your local electrical code should factor into your decision.
When evaluating options, compare how each product’s installation features align with your ceiling structure, desired fixture weight, and maintenance preferences. This helps ensure a safe, durable, and code-compliant ceiling fan installation.
