The most reliable method is to use a post support system that holds the column securely in position while the concrete cures. The Big 5 Adjustable Post Support clamps onto square tubing and uses adjustable bracing arms to keep the post plumb, level, and stable throughout installation.
Yes. The Adjustable Post Support is designed for a wide range of square tubing installations, including carports, pergolas, shade structures, fencing, gate posts, signage, and structural steel columns. It helps ensure accurate alignment and reduces installation time on-site.
Unlike temporary timber bracing, an adjustable steel post support provides precise alignment, greater stability, and repeatable results. It reduces the need for additional labour, allows hands-free concreting, and helps prevent post movement or rotation while the concrete sets.
