A bracket mountable electrical box having a mounting assembly or device that can secure the electrical box to a mounting bracket. The mounting assembly or device can include one more arms that can define at least a portion of a channel that can receive the mounting bracket. The channel can be selectively closed, or at least partially deformable, in a manner that can assist in retaining the engagement between the mounting bracket and the mounting assembly or device, and thus the electrical box. Such configurations can accommodate securing the electrical box to the mounting bracket without at least the use of additional tools.
