Whether you're advertising a sale, promoting an event, or displaying your business outdoors, a banner is only as effective as the way it's installed. One small but important feature that helps keep banners securely in place is the grommet.
Banner grommets make installation easier while helping reduce stress on the material during use. They provide reinforced attachment points that allow banners to be hung with common hardware such as zip ties, ropes, hooks, or bungee cords.
If you're ordering a custom banner for the first time, here's what you need to know about banner grommets, where they're placed, and whether your banner needs them.
What Are Grommets?
A grommet is a reinforced ring inserted into a hole in a material. On banners, grommets create durable attachment points that make it easier to secure the banner without placing direct stress on the printed material.
Although grommets are used across many industries—from clothing and curtains to tarps and tents—they're especially common on vinyl banners because they help support the banner during installation and display.
What Do Banner Grommets Look Like?
Banner grommets are small circular rings installed around pre-cut holes along the edges of a banner. They are commonly made of metal, although some applications may use plastic grommets depending on the material and intended use.
Once installed, the ring reinforces the opening, allowing ropes, zip ties, hooks, or other fasteners to pass through without the banner material tearing as easily.
What Are Grommets on a Banner Used For?
While grommets are small, they play an important role in how a banner performs throughout its lifespan.
Make Banner Installation Easier
Grommets provide ready-made attachment points, making banners quick to install using common mounting hardware. Instead of creating your own holes, you can simply thread zip ties, rope, hooks, or bungee cords through the grommets and secure the banner where needed.
Help Prevent Tearing
Without reinforced attachment points, the material around a mounting hole can experience concentrated stress, especially if the banner is pulled tight or exposed to movement. Grommets distribute that stress around the opening, helping reduce the likelihood of tearing during normal use.
Improve Banner Stability
Properly placed grommets allow tension to be distributed more evenly across the banner. This helps keep the banner flatter and more secure, reducing sagging or shifting after installation.
Support Repeated Use
Many promotional banners are used more than once for recurring events, seasonal sales, or trade shows. Grommets make it easier to remove, store, and reinstall banners without creating new attachment holes each time.
Where Are Grommets Placed on a Banner?
The placement of grommets depends on the banner size and how it will be displayed, but most follow standard installation practices.
Standard Grommet Placement
Grommets are typically installed around the perimeter of the banner to provide multiple attachment points. This allows the banner to be secured evenly across its edges rather than relying on only a few fasteners.
Corner Grommets
Nearly all grommeted banners include reinforcement at each corner. Since corners often experience the greatest pulling force during installation, these attachment points help keep the banner securely mounted.
Additional Grommets for Larger Banners
As banners increase in size, additional grommets are often added along the edges. Extra attachment points help distribute tension more evenly and reduce stress between mounting locations.
Can Grommet Placement Be Customized?
Some print providers offer custom grommet placement for specialized installations or unique display requirements. If your banner needs to fit a specific frame, structure, or mounting system, check with your printer to see what finishing options are available.
Do You Need Grommets on Your Banner?
Not every banner requires grommets, but they're one of the most popular finishing options because they're compatible with many installation methods.
When Grommets Are Recommended
Grommets are often a good choice for:
- Outdoor advertising
- Storefront banners
- Fence banners
- Community events and festivals
- Sporting events
- Temporary promotional displays
- Banners that will be reused
Situations Where Grommets May Not Be Necessary
You may not need grommets if your banner is:
- Installed inside a banner stand
- Mounted within a frame
- Displayed using another finishing method designed for your hardware
- Permanently secured without exposed attachment points
Questions to Ask Before Choosing Grommets
Before selecting banner finishing options, consider:
- Where will the banner be displayed?
- How will it be mounted?
- Will it be used indoors or outdoors?
- Will you reuse the banner for future events?
- Does your mounting hardware require reinforced attachment points?
Answering these questions can help determine whether grommets are the right choice for your application.
How to Hang a Banner With Grommets
One advantage of grommets is their flexibility. They work with several common installation methods depending on where the banner will be displayed.
Using Zip Ties
Zip ties are one of the simplest ways to attach banners to fences, railings, and temporary structures. Thread a zip tie through each grommet and tighten it enough to hold the banner securely without overstressing the material.
Using Rope or Cord
Rope or cord works well for suspending banners between poles, posts, or other support structures. Using multiple attachment points helps distribute the banner's weight more evenly.
Using Hooks or Screws
For walls, buildings, or other fixed surfaces, hooks or screws can be used with appropriate hardware to mount banners through their grommets.
Using Bungee Cords
Bungee cords provide a small amount of flexibility, allowing the banner to move slightly instead of remaining under constant tension. This can be helpful for banners displayed outdoors where movement is expected.
Installation Tips
For the best results:
- Use all available grommets whenever possible.
- Apply even tension across the banner.
- Avoid pulling the banner excessively tight.
- Match your hanging hardware to the installation surface.
Inspect hardware periodically if the banner will remain installed for an extended period.
Design Tips When Adding Grommets
Although grommets are installed after printing, it's still important to account for them during the design process.
Keep Important Content Away From Edges
Avoid placing logos, text, QR codes, or other important design elements too close to the banner's edges. This helps ensure they remain fully visible after finishing and installation.
Account for Mounting Locations
Think about where the banner will be displayed. If attachment points will be visible, avoid positioning critical information where ropes, zip ties, or other hardware could distract from the message.
Maintain Adequate Safe Margins
Following recommended safe margins gives your design enough clearance from trimming and finishing areas while helping preserve a clean, professional appearance.
Common Banner Grommet Mistakes to Avoid
Choosing the right finishing option is only part of the process. Proper installation and design also contribute to banner performance.
Choosing Too Few Attachment Points
Large banners need enough mounting points to distribute their weight evenly. Relying on only a few fasteners can place unnecessary stress on the material.
Ignoring Environmental Conditions
Outdoor banners may experience wind, rain, or frequent movement. Selecting appropriate mounting hardware and securing the banner properly can improve its overall performance.
Blocking Grommets With Design Elements
Avoid placing essential information directly next to the edges where mounting hardware may partially obstruct the design.
Using the Wrong Hanging Hardware
Choose hardware that's appropriate for both the installation surface and the banner's intended use. The right combination helps keep the banner secure while reducing unnecessary strain on the material.
Banner grommets may be a small feature, but they make a big difference in how a banner is installed, displayed, and maintained. By reinforcing attachment points, they help simplify installation, improve stability, and support repeated use for promotional displays, events, and business signage.
Whether you're ordering a banner for indoor or outdoor use, understanding how grommets work can help you choose the right finishing option for your display and get the most from your investment.
