The anchor bolt is sold separately and must be specified by the Designer/Engineer of Record as it would be specific to the project (i.e. is it new or existing concrete, demand loads, concrete strength, anchor location, local building codes, etc.). Thank you!
No, these would not be recommended for a railing application. Except for the MPBZ moment post base, post bases do not provide adequate resistance to prevent members from rotating about the base and are therefore not recommended for non-top-supported installations (such as fences, railings or unbraced carports). The top of the post must be restrained from moving horizontally by some other means, e.g., by tying the roof into a supporting structure or by adding knee bracing between the posts and beams (which of course would not be ideal for a railing condition). Alternatively, see the MPBZ for a post base that provides moment resistance for columns or posts. Thank you!
