Abstract: A bannister attachment especially adapted for facilitating the mounting of a child safety gate includes a longitudinally extending body member possessing on a front face two spaced, substantially parallel rails defining a central recessed mounting channel adapted for releasably receiving extensible abutment feet extending from a side edge of a conventional child safety gate. Top and bottom box frame members secured to the elongated body member are selectively mountable around the end post of a bannister of a stairway to semi-permanently secure the bannister attachment at the head of a stairway. The bannister attachment provides a safe, secure, and ornamentally attractive device for facilitating the mounting of a conventional child safety gate.
