The Simpson Strong-Tie HD9B Holdown is a self jigging anchor that ensures the bottom bolt that attaches to the stud or post is seven times the diameter of the bolt. This holdown uses the same design as the HDQ8-SDS2.5 holdown that is proven to greatly reduce deflection while under load. All the HDB style holdown anchors are designed to provide loads for intermediate-load-range shearwalls, braced wall panels and lateral applications. The HD9B must be connected to a minimum of 3-1/2" of material.

I needed 24 Simpson post bases for a project. Amazon had 8, for an oddly low price, so I ordered them. I ordered the balance from DHC for a few dollars more, and they arrived in two days, drop-shipped from Simpson. The ones from Amazon came one at a time over the next ten days. Won't make that mistake again. 5/14/17
