These mounts are similar to our popular 3-way mounts without the clamp.  If you know that your installation will not require the clamping bracket supplied in the 3-way mounts, you can save a couple of dollars with these mounts.  All of these mounts are specifically used for mounting antennas to a flat vertical surface, such as the side of a van or motor home.  These brackets are made from cold rolled steel and are finished with chrome plating.  The K-24 is complete with FireStik's K-4 antenna stud with ring terminal connector.  The K-24A is complete with thier world famous K-4A antenna stud with screw on coax cable connector.  These mounts are also available in stainless steel versions.  All mounts come complete with mounting hardware.  The actual size of the bracket is 2.25" (57mm) wide by 2.9" (74mm) high (4.2" (107mm) with stud).  They protrude outward from the vertical surface 1.9" (48mm).
