These items come with a 50" tall post. The "2-piece post" version is much cheaper to ship than the "1-piece post version", and the 2-piece post is just as strong! 
All flat posts are predrilled for mounting standard 12"x18" or 18"x24" traffic signs (*signs not included). All needed nuts and bolts included.
The round post version included two pipe post brackets designed for use with 1 5/8" pipe posts.
The 14" cast iron base weighs 20 lbs.. The 17" base weighs 24 lbs.. Both of the cast iron bases also have mounting holes that allow you to use concrete bolts to secure the cast iron base to the pavement for a permanent installation (*concrete anchor bolts not included).
We also have "Replacement Parts" available for the B14 and B17.
