Questions & Answers


Can this be used on a 4x6?

Asked by Jason September 6, 2020

For post bases that do not attach to all four sides of the post, the post may be wider than the base and overhang the base in one direction as long as the bearing area provided by the base is sufficient for the post. Note: the APBVB44R is sized for a rough (true to size) 4x6. If you're looking for a base for nominal lumber (i.e 4x = 3 1/2" actual), please see the ABP44. Thank you!

How do you secure the 4x4 to the anchor? What size bolt and does it feed all the way through?

Asked by Stan August 2, 2020

The APVB44R requires a 5/8" diameter *anchor bolt to connect the base to the concrete. The post connects to the base with a quantity of 4 - Outdoor Accents SDWS22312DBB structural wood screws inserted through an STN22 washer. *it is up to the Designer/Engineer of Record to specify the anchor bolt type, length and embedment. Thank you!

The video shows it being used only on a concrete pad. Could this base be used on a wooden deck?

Asked by Rudy June 5, 2020

This base is only tested/rated for installation on concrete. Thank you!

What I like about it: The base is hollow, so water easily drains away from the post. Made of nice, thick metal. Satin black in color. Requires an anchor bolt to secure to foundation. Looks great with the rough cedar 4x4 What I don't like: Doesn't come with screws or decorative nuts. You'll pay more for these than the cost of the bracket. It says the bracket is adjustable, but it adjusts in only one direction The bracket opening is way bigger than the 4x4. So the bracket bends in when secured by the screws
