Thank you for reaching out to Grand Brass Lamp Parts!
Our Ceiling Semi-Flush Mount Fixture for Dish Type Glass Shades (SKU: FXFD100NP) has the following approximate dimensions, as shown in the product's dimensional photograph:
- Ceiling Canopy Diameter: 5 inches
- Overall Fixture Height: 10-1/8 inches, from the top of the canopy to the bottom of the fixture
- Overall Socket Assembly Width: 8 inches
- Socket Assembly Depth: 4-3/4 inches
These measurements are approximate and provided for reference purposes. Unfortunately, we do not currently have additional verified measurements for the individual socket widths, spacing between the sockets, or the distance from the sockets to the bottom of the fixture.
For reference, please see the dimensional photograph below:

Regarding your request for a custom rod length of approximately 4 feet above the sockets, please contact Sales@grandbrass.com with your desired dimensions and installation requirements.
One of our lighting experts may be able to assist you with obtaining additional measurements and determining whether a custom-length rod configuration is available for your project.
