Pergola Bracket Kit for 4x4 Inch Posts

This kit provides four 3-way carbon steel corner brackets designed for standard 4x4 inch lumber with an actual inner size of 3.5x3.5 inches. Each bracket uses 2 mm thick material with a black powder coating and integrated drainage holes to protect wooden posts from moisture damage. The package includes 112 self-drilling screws and 16 stainless steel expansion bolts for immediate assembly.

Suited for Square Timber Frames.

Builders constructing gazebos, patio pergolas or log cabins with square 3.5-inch beams will find the brackets match the timber profile exactly. The 3-way design handles corner junctions where three members meet at 90 degrees. Installers working with round logs, metal posts or lumber thicker than 3.5 inches cannot use these brackets without modification.

3.5 Inch Inner Width Decides Fit

The critical measurement is the 3.5 inch (92 mm) internal cavity that receives the post. Verify your timber measures 3.5 x 3.5 inches before purchasing; a larger or smaller cross-section will prevent the bracket from seating correctly. The 90-degree boot structure and full-coverage wings are engineered around this single dimension.

Questions about this item

Will the 3.5 inch inner size fit my 4x4 posts?

Yes, the bracket inner dimension is 3.5 x 3.5 inches (92 x 92 mm) to match the actual size of standard 4x4 soft or hardwood beams.

How do I anchor the brackets to a concrete patio, and what step is often missed?

Drill into the concrete and use the 16 included 304 stainless steel expansion bolts; the step often missed is tightening each bolt to the specified torque so the bracket seats fully on the post.

What hardware will I need to replace if the self-drilling screws strip out over time?

The kit supplies 112 self-drilling screws; keep spares on hand because they are the primary fasteners securing the wooden beams to each carbon steel bracket.
