Abstract: A junction box is adapted for flush and straight mounting in a hollow core of a masonry block, without the use of debris or the like in the core. The junction box has a thickness along a pair of side walls thereof defined by a separation of a generally-open front face from a generally-closed rear face. The junction box has a resilient tail-like member that extending away from the rear face of the junction box. The tail-like member has first and second ends with at least one bend or curvature along an intermediate portion and a length such that, in a compressed state, the second end bears against a first inside wall of the hollow core and at least portions of the junction box front face bear against an opposing second inside wall of the hollow core.
