Abstract: This document describes a high-security mounting system for retail device display. The mounting system includes a shelf and table system having a variety of security features that help reduce theft of electronic devices presented for retail display. The devices are mechanically fastened to a stand, which is mechanically fastened to a mounting surface of the mounting system using a series of holes defined in the mounting surface. A tray is fastened to an underside of the mounting surface and is usable to house the devices' electrical cords extending through the holes. A rigid placemat is attached to the stand and wraps around an edge of the mounting surface to capture a portion of the underside of the mounting surface to resist a pull force on the stand. Optionally, a riser can be used to adapt a device's configuration of mounting hardware to the holes in the mounting surface.
