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 ordered 6 galvanized metal post bases, which were bulky and heavy. Shipping cost was quite high. DHC contacted me to see if I would agree with their plan to ship from a "different location nearer to me" to save shipping costs! Of course I agreed. Awesome that a company cares enough to go to that length to help a customer. I will order again from DHC for sure! Thank you! 03/13/17
