Plan for Strong Joints: Position five sets of holes strategically for structural integrity.

Label Sections Clearly: Mark “center,” “left,” and “right” sections, along with directional indicators (top, bottom, inside wall).

Define “Inside Wall”: The perspective from inside looking toward the street.

Ensure Proper Alignment: Arrange all sections in their final positions before drilling.

Use Correct Drill Bit: Choose a size that fits T-nuts for a secure connection.

Secure Fit for Water Resistance: Proper drilling and alignment ensure a strong, watertight seal.
