What base do you use?
It is used in connection with any Kingpin pedestal. The base depends on what type of Kingpin post you use. If you need some assistance selecting contact us at the number at the top of the page.
What measurement do the 7 x 7 dimensions refer to? Also, how tall is the actual post/mount assembly, once it's all assembled?
This product only includes the base mount, not the post. The 7 x 7 inch dimensions refer to the overall measurements of the base of the mount.
