Abstract: A merchandise display and anti-theft system, for use in displaying an electronic device such as a laptop computer, comprising a base plate and a rail. The rail is mounted transversely onto a merchandise display shelf. The electronic device is selectively attached to the base plate by a crossbar. A front bracket assembly and a rear bar are provided to restrict the extent to which the electronic device may be moved in a forward or reverse direction upon the base plate. The crossbar, front bracket, and rear bar are fastened to the base plate with screws extending from beneath the base plate, in order to prevent removal of the electronic device. After mounting the rail to the shelf and affixing the base plate to the rail, the screws which hold the cross bar, rear bar, and front bracket to the base plate are inaccessible, thereby preventing theft of the electronic device selectively affixed to the base plate.
