The Simpson Strong-Tie OCB810 Ornamental Column Base is a precision-engineered cast-in-place column base designed to prevent wood members from rotating while delivering a refined, finished appearance. Featuring a flat black powder-coated finish, the OCB810 offers a significantly more durable and better-looking result than standard paint applications. The base plate is specifically designed to sit flush with the concrete surface, creating a clean, seamless transition between structure and finish. Manufactured in the United States, this column base is built to meet the demands of both structural integrity and ornamental appeal.

Frequently Asked Questions

How should the OCB810 base plate be installed relative to the concrete surface?

The OCB810 is designed as a cast-in-place column base, and the bottom of the base plate should be installed flush with the concrete surface. This flush-mount design creates a clean, seamless transition between the structure and the finished surface.

What fasteners are required to install the OCB810?

Installation of the OCB810 requires two 3/4" machine bolts. Ensuring the correct fasteners are used is important for achieving the rated load capacity of the column base.

What is the minimum side cover required for the OCB810 to achieve full load capacity?

A minimum side cover of 3 inches is required for the OCB810 to achieve its full allowable load capacity. If this minimum side cover cannot be met, the allowable loads must be reduced accordingly.

How does the powder-coated finish on the OCB810 compare to standard paint, and what are the column base dimensions?

The OCB810 features a flat black powder-coated finish, which provides a more durable and attractive appearance than standard paint applications. The base has a W1 dimension of 71/2 in. and a W2 dimension of 91/2 in., and its Gauge 3 heavy-duty construction supports allowable loads that are increased 60% for wind or earthquake loading.
