Our fixtures are all supplied with a mounting bracket that can mount to most electrical or junction box sizes. Fixtures will either be supplied with a 4" universal circle bracket, or a 4" strap bracket depending on how the fixture is mounted. Any junction box that is 4" or less at it's mounting points will be compatible with the brackets we supply, and will be concealed behind the fixture canopy.
Important Note: The U/2 sconce and U/1 light fixture require use of a 4" round junction box due to the canopy and mounting system used.
