To use the M-2 mount with an import tripod that uses a 10 mm attachment bolt (such as many Vixen tripods, Celestron CG4, CG5, VX, Etc), use this column. Like the M-2, this column is made in the USA of 6061-t6 aluminum. The M-2 mount head bolts to the top of the column with three side screws. This eliminates rotation between the mount and column.
Add the extension column only to the mount head purchase. Mounts to import tripods using a 10 mm attachment bolt.
Note: This column is made for the M-2 head. The head attaches to three holes at the top of the column. So the column will not work with our former M1 mount
