Abstract: A rail clamp assembly that improves the mechanisms whereby a rail is secured to the rail clamp assembly comprising a mounting base having a diagonally and generally elliptical-shaped channel formed therethrough and further comprising a clamp member. The clamp member has a diagonally formed throughway formed therethrough. The clamp member is received by the mounting base such that the throughway of the clamp member is aligned with the channel. The clamp member further comprises a protrusion which is received within a slot of the rail and the mounting base comprises a protrusion which is received within an adjacently situated slot of the rail. A side wall of the mounting base and an inclined surface of a flange of the clamp member are configured to engage with an inclined surface of the rail to further secure the rail to the assembly.
