A cracked grommet can turn a routine restring into a string-breaking problem. These small plastic parts protect string where it passes through the racket frame, and the right replacement depends on the frame’s design—not just its brand or head size.
Most rackets use a standard grommet strip and a bumper guard, but some have shared holes, longer grommets or special port systems. Here’s how the main tennis racket grommet types work, what to look for, and five frame-specific replacement options to consider.
What Do Tennis Racket Grommets Do?
Grommets line the holes in a racket frame. They keep strings from rubbing against sharp or exposed graphite as the strings move during impact. The bumper guard is the protective strip around the top of the frame; it often connects to the grommet strip and helps shield the racket when it scrapes the court.
Grommets wear over time. Look for cracked or missing plastic, a sharp edge near a string, or a string that repeatedly breaks at the frame. If you spot damage, have a stringer check it before the next restring. A fresh set can protect your strings, but it must match your exact racket model and generation.
Common Tennis Racket Grommet Types
| Type | How it works | What to know |
|---|---|---|
| Standard grommet strip | A row of small tubes sits in the frame holes and guides individual strings. | Common on conventional frames. The strip is usually replaced as a set. |
| Bumper guard | A tougher strip covers the frame across the racket head’s top edge. | It takes wear from court contact. Many replacement kits include it with the grommet strip. |
| Shared-hole grommets | A wider or specially shaped grommet lets two strings pass through one frame hole. | Follow the racket’s stringing pattern; the strings must sit correctly without pinching. |
| Long or enlarged grommets | These give a string more room to move or change its angle as it leaves the frame. | They’re part of a racket’s design. Replacing them with standard pieces can affect fit and string movement. |
| Port systems | Larger openings and inserts guide strings in place of many small conventional grommets. | Seen on certain Prince O3 frames. Use the correct port inserts and stringing instructions. |
Five Frame-Specific Replacement Options
These are examples of replacement kits to investigate, not universal parts. Choose the kit listed for your racket’s exact model, head size, string pattern and generation. Two rackets with the same name can use different grommet shapes.
1. Babolat Pure Drive replacement grommet and bumper set
A sensible choice for a Pure Drive owner whose bumper has worn down from frequent court contact. A model-matched set restores the original coverage and string-hole fit. Pros: Made for the frame’s layout; a practical refresh for a well-used racket. Cons: Pure Drive versions differ, so a set for one generation may not fit another.
2. Wilson Blade 98 replacement grommet and bumper set
Blade players can look for the set made specifically for their 98-square-inch model and string pattern. This is especially useful if the racket is otherwise in good shape but the bumper or a string hole has become damaged. Pros: Preserves the intended hole layout and frame coverage. Cons: Blade 98 versions and patterns vary; check both before ordering.
3. HEAD Speed MP replacement grommet and bumper set
For a Speed MP, a matching kit is preferable to trying to adapt a similar-looking strip. It’s a straightforward replacement option when the bumper is worn or a grommet no longer protects the string. Pros: Designed around the model’s frame holes. Cons: MP, Pro and other Speed models are not automatically interchangeable.
4. Yonex EZONE 100 replacement grommet and bumper set
An EZONE 100 owner should choose a set marked for the right EZONE generation and frame size. Keeping the original grommet layout helps the strings sit as intended, particularly around shared or specially shaped holes. Pros: A model-specific fit is more reliable than generic parts. Cons: EZONE 98 and 100 sets, or different model years, may not match.
5. Prince O3 port inserts and grommet parts
If you play with a Prince O3 racket, look for the correct port inserts or replacement parts for that exact frame. O3 openings are not ordinary grommet holes, so a standard strip is not a substitute. Pros: Maintains the racket’s designed port setup. Cons: O3 parts are frame-specific and may take more care to fit; ask a stringer if you’re unsure.
How to Choose and Replace Grommets
- Check the full model name and generation. Use the markings on the racket or ask a knowledgeable retailer or stringer to identify it.
- Replace the set when several areas are worn. One damaged grommet may sometimes be repaired, but widespread cracking usually calls for a full strip and bumper replacement.
- Don’t force a close-looking part. A poor fit can leave a string exposed or make installation difficult.
- Consider the timing. Grommets are easiest to replace during restringing, when the strings are already out. If a string is sitting against bare frame material, deal with it sooner.
Installation takes patience: the strip has to sit evenly, and strings must pass through the correct holes without being trapped. Many players leave the job to their stringer, especially with shared holes or port systems. Avoid levering hard against the frame with a sharp tool; that can damage the racket while you’re trying to protect it.
Frequently Asked Questions
Do grommets affect how a tennis racket plays?
They mainly protect the strings and frame, but a racket’s special grommet or port design can influence how strings move. Replace worn parts with the correct design rather than changing the setup by improvising.
Can I replace one broken grommet instead of the whole set?
Sometimes. A stringer may be able to fit a replacement tube or make a small repair if the damage is isolated. If the strip is brittle or several holes are worn, replacing the full set is usually the better fix.
Are racket grommet sets universal?
No. They’re shaped for particular frames, and even different generations of the same model may use different parts. Confirm the exact model, size and year where possible.
When should I replace the bumper guard?
Replace it when it is worn through, split, loose or no longer covers the frame properly. A scraped bumper is common, but exposed frame material or strings touching a sharp edge need attention.
Final Thoughts
Standard strips, bumper guards, shared-hole grommets, enlarged grommets and port systems all serve the same basic purpose: protecting the string and frame. The key is matching the replacement to your racket. Check for wear during restringing, and ask your stringer to identify the right part if the model or generation is unclear.
