Wedge orientation: Install the wedge so it clamps the rail securely and evenly when tightened. Bonding: Use the included grounding/bonding screw as required by local electrical code. Keep drain path clear: If your installation uses a drain hole below the anchor, keep it clear to reduce standing water and corrosion. Seasonal checks: Re-check rail tightness periodically, especially after heavy use or freeze/thaw cycles.
