  • Patent number: 12372200
    Abstract: A mounting bracket for an electrical box can be configured for use with a support that has a first and a second rail. The mounting bracket can include a first attachment device that is secured to mounting body and a second attachment device that is secured to the mounting body opposite the first attachment device. To secure the mounting bracket to the support, the first attachment device can be configured to engage one of the first rail or the second rail and the second attachment device can be configured to engage the other of the first rail or the second rail. Each of the first and second attachment devices can include a first arm configured to extend on a first side of the corresponding first or second rail, and a second arm configured to extend on a second side of the corresponding rail, opposite the first arm.
