The CB is designed to connect posts to concrete foundations for a wide range of lumber, glulam, and engineered wood product sizes. This column base is either cast-in-place or wet set into the concrete where the bottom of the base plate sits flush with the concrete for full post bearing. The CB is ideal for columns that require high structural values and rugged performance.

Outstanding Quality

These ties are super heavy duty and I have no doubt they will stand up to the job they are designated for. Considering the price, and the quality of the competetition, these are a real bargain. The delivery was free and super fast. I recieved them only a few days after initially ordering them. I highly recommend them if you need a quality way to support a 6x6 onto concrete.
