The Manfrotto 243 Car Window Mount Pod with 234RC Swivel Tilt Monopod Head is for use with a camera, binocular or spotting scope when viewing from an automobile. It can also clamp to any other thin, flat material similar to tempered car window glass. The 243 head swivels 90° in either direction on its single pivoting axis, and features a reversible 1/4″-20 mounting thread. The maximum load is 5.5 lbs, but since it clamps to glass, the max weight allotment may vary by the strength of the glass. Thus, only lighter weight optical devices should be used in conjunction with this mount.
