Simpson Strong-Tie CB44PC 4x4 Column Base with Black Powder-Coated Finish is a cast-in-place column base engineered by Simpson Strong-Tie to help prevent wood members from rotating at the base. Designed so the bottom of the base plate sits flush with the concrete surface, this column base delivers a structurally sound connection point for 4x4 posts. Its textured black powder-coated finish provides a significantly more durable and better-looking result than standard paint finishes.

Key Features

• Cast-in-place design with base plate installed flush with the concrete surface
• Helps prevent wood members from rotating about the base
• Textured black powder-coat finish - more durable and better looking than standard paint
• Engineered for 4x4 column size applications
• Allowable loads increased 60% for wind or earthquake loading (no further increase allowed; reduce where other loads govern)
• Minimum side cover for full loads is 3" for CB models
• Made in the United States by Simpson Strong-Tie

Approved Applications

• Cast-in-place post base installations where the base plate must be flush with concrete
• Structural connections requiring resistance to wood member rotation
• Applications subject to wind or earthquake loading (60% load increase allowable)
• Not recommended for non top-supported installations such as fences or unbraced carports, as post bases do not provide adequate resistance to prevent members from rotating about the base

Frequently Asked Questions

How should the CB44PC be installed relative to the concrete surface?

All CB models should be installed with the bottom of the base plate flush with the concrete surface. This ensures proper load transfer and structural performance as designed.

What fasteners are required to install the CB44PC?

The CB44PC requires (2) 5/8" bolts. Always use all specified fasteners to achieve the rated allowable loads.

Can the CB44PC be used for fences or unbraced carports?

No. Post bases like the CB44PC do not provide adequate resistance to prevent members from rotating about the base and are therefore not recommended for non top-supported installations such as fences or unbraced carports.

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

A minimum side cover of 3" is required for CB models to achieve full allowable loads. Ensure this clearance is maintained during installation.

Note: Product dimensions and/or screw or bolt holes may differ from picture. Use all specified fasteners. Allowable loads have been increased 60% for wind or earthquake loading. No further increase allowed; reduce where other loads govern.
