Good Anchor Ties, but not the Best
Mounts easily, but not the sturdiest base anchor tie for a larger arbor. Had to brace top of 4 arbor corners to keep the light sway down. Originally purchased 4 other stronger Simpson Strong Ties, but they were too big at the base to anchor to an 8” diameter concrete post. I guess I could have bought a 10” Auger bit, but couldn’t justify the 1 time use for over $100.00.

Secure base for railing post
I used these to secure the handrail post for my porch to a concrete pad at the base of the stairs. Set in place with threaded rod and epoxy into a drilled hole, and this holds the post securely. Added some structural screw side connectors for additional security

    Good post base
    I intalled this post base onto a retaining wall. The top of the wall was filled with concrete so I used a Simpson Strong Tie to secure the post base into the concrete.

      I used this to create a shear point for our mailbox mounting post. The part mated up nice & square between the lower and upper post sections.

      I like how Simpson has redesigned this product into one piece instead of the base plate being separate. It makes it easier to install.

      this product was used for a new pergola addition that is attached to the house. it served our purposes great, the only downside was the pilot holes had to be redrilled in order to get the tapcon screws to go in all the way. There isn't enough clearance for the head of the drill if you use the holed provided. Once installed they were super solid and worked perfectly!

      A great post anchor when you can't 'go to ground'!
      When you are trying to make a firm upright connection to a flat surface this is a great fix! It mounts to both surfaces securely and makes a stable post for your project.

      Just what I needed.
      I used two of these to anchor the stair rail posts at the base of stairs to a new deck I built. I also have angle ties anchoring the stair stringers to the concrete pad on the other side. By tying the posts to the post base and the stringers it made everything very sturdy.
