Distributing grommets or attachment points on PVC flex banners in a strategic manner is crucial for ensuring optimal display and preventing issues such as sagging, wrinkles, or damage. The placement of grommets should provide even tension across the banner and allow for secure installation. Here's how to distribute grommets or attachment points for optimal display:

1. Determine Banner Size and Orientation:

   - Start by determining the size and orientation of the PVC flex banner. Consider whether the banner will be displayed horizontally (landscape) or vertically (portrait).

2. Calculate Grommet Placement Spacing:

   - Calculate the spacing between grommets or attachment points based on the banner's dimensions and the desired tension. In general, spacing between grommets should be approximately 24 to 36 inches (61 to 91 cm) apart, but this can vary based on the banner's size and the expected wind load.

3. Plan Grommet Rows:

   - Divide the banner into rows for grommet placement. Typically, banners have grommet rows at the top and bottom edges and additional rows evenly spaced along the sides. The number of rows and their placement may vary based on the banner's size and intended use.

4. Mark Grommet Locations:

   - Use a pencil or chalk to mark the precise locations where grommets will be inserted. Ensure that the markings are straight and evenly spaced along the banner's edges.

5. Insert Grommets:

   - Follow the manufacturer's instructions to insert grommets at the marked locations. Grommets consist of two parts: the grommet itself and the washer. The grommet is placed on one side of the banner, and the washer is placed on the opposite side.

6. Reinforce Banner Edges:

   - Consider reinforcing the edges of the banner with extra layers of PVC material or by creating a hem. This provides additional strength and durability, especially for large banners.

7. Stagger Grommets Along the Sides:

   - To ensure even tension and prevent sagging, stagger the grommets along the sides of the banner. In other words, the grommets in adjacent rows should not align vertically. This distributes the tension more evenly.

8. Use Corner Grommets:

   - For larger banners, consider adding corner grommets or attachment points. These can be used to secure the corners of the banner and prevent flapping.

9. Reinforce Grommet Areas:

   - Reinforce the areas around the grommets with additional material or patches to prevent tearing, especially in windy conditions.

10. Consider Wind Load:

    - If the banner will be displayed outdoors and is susceptible to wind, you may need to use additional grommet rows or consider wind slits or perforations to allow wind to pass through.

11. Inspect and Adjust:

    - After inserting the grommets and securing the banner, inspect the tension and appearance. Adjust the tension as needed to ensure the banner is taut and free from wrinkles.

12. Securely Attach Accessories:

    - If using ropes, bungee cords, or other accessories for banner installation, attach them to the grommets or attachment points securely. Ensure that the banner is evenly tensioned.

Proper grommet placement and distribution are essential to achieve a professional and visually appealing display for PVC flex banners. Careful planning and attention to detail during installation can ensure that the banner remains secure and aesthetically pleasing throughout its use.
