A tennis stringing starting clamp gives you a secure way to hold string before the machine’s regular clamps can take over. It is especially useful when beginning the mains, handling a short string end, or working with a machine whose fixed clamps cannot reach a convenient spot.
Although it looks simple, a starting clamp can save time and prevent loose strings during a job. The right choice depends on how often you string, how much you want to spend, and whether you need it as a main tool or an occasional backup.
What a Tennis Stringing Starting Clamp Does
A starting clamp is a spring-loaded tool with two jaws that grip a string. Unlike a machine’s fixed clamps, it is not attached to the turntable, so you can place it wherever the job requires. It holds tension on a string while you pull another section, start a string bed, or make a temporary “bridge” to tension a short end.
For example, when starting the mains, you can clamp the first main outside the frame, pull tension on its partner, and then continue the pattern. It can also help when tying off a knot, though you should use it to control the string—not as a substitute for following the machine and racket manufacturer’s recommended tensioning process.
Five Starting Clamps to Consider
These options suit different budgets and stringing setups. Check the current model details and included accessories before buying, since designs and availability can vary by retailer.
| Starting clamp | Best suited to | Advantages | Trade-offs |
|---|---|---|---|
| Gamma Starting Clamp | Home and frequent stringers | Recognizable stringing accessory; practical for regular use and as a backup clamp | Costs more than basic generic options; check jaw condition and alignment |
| Tourna Starting Clamp | Players who want a dedicated stringing tool | Simple, purpose-built design that can handle common starting and bridge tasks | Compare spring feel and jaw finish with other models before choosing |
| Stringway Starting Clamp | Stringers who value precision and build quality | From a specialist stringing brand; a considered choice for a busy setup | May be harder to find, depending on your location |
| Babolat Starting Clamp | Babolat users and stringers buying matching tools | Useful dedicated option from a major racket-equipment brand | Availability can vary; compare its price with other specialist clamps |
| Pro’s Pro Starting Clamp | Budget-conscious or occasional stringers | Often a lower-cost way to add a starting clamp to a home toolkit | Inspect the jaws and spring carefully; consistency can vary between examples |
How to Choose Between Them
If you string several rackets a week, a well-made clamp with smooth, even jaws is worth paying for. A clamp that grips consistently is easier to trust when you are holding tension on a delicate string. If you string only your own racket now and then, a budget model may be adequate, provided it grips securely and does not leave marks.
Also consider the rest of your setup. A starting clamp is handy on both drop-weight and electronic machines, but it does not fix poorly adjusted fixed clamps or replace a tension head. If possible, test the clamp on a spare piece of string before using it on a fresh set.
How to Use a Starting Clamp Safely
- Check the jaws. They should meet evenly, with no dirt, sharp edges, or obvious damage.
- Place it on the string. Position the string straight between the jaws. Avoid clamping across a knot or a damaged section.
- Let the spring do its job. Close the handles enough to grip firmly, but do not add extra force that could crush or flatten the string.
- Keep it clear of the frame. Make sure the clamp does not rub against the racket or press on a grommet as the string moves.
- Release it under control. Hold the string securely before opening the clamp, especially if it is carrying tension.
Different strings respond differently to clamping. Soft multifilament and natural gut can be more vulnerable to crushing or surface damage than many durable polyester strings. If the clamp leaves a deep indentation, slips, or frays the string, stop and inspect the jaws rather than simply squeezing harder.
Common Uses Beyond Starting the Mains
- Creating a bridge: Grip a short string section so the tension head can pull it when there is not enough length to reach normally.
- Holding a string during a tie-off: Keep the string from slipping while you finish a knot, using care not to overload the frame or string.
- Backing up a fixed clamp: Provide an extra hold when a fixed clamp cannot reach the ideal position.
- Checking clamp performance: A starting clamp can help you spot string movement, though it should not replace proper calibration and adjustment of your machine.
Think of it as a flexible helper, not a cure-all. If a fixed clamp slips on every job, clean and adjust it according to the machine’s instructions. Using a starting clamp to compensate for a faulty machine clamp can hide the real problem.
Frequently Asked Questions
Do I need a starting clamp to string a tennis racket?
No. Many rackets can be strung without one, especially on machines with well-positioned fixed clamps. It becomes more useful for starting mains, dealing with short string ends, and adding flexibility to your setup.
Can a starting clamp damage tennis string?
Yes, if the jaws are dirty, damaged, misaligned, or squeezed too tightly. Test the clamp on spare string and check for flattening, fraying, or deep marks before using it on a racket.
Can I use a starting clamp instead of a machine clamp?
It can serve as a temporary backup in some situations, but it is not a replacement for properly adjusted machine clamps. Follow your machine’s instructions and make sure the string is held securely before releasing tension.
Is an expensive starting clamp always better?
Not necessarily. A reliable clamp should grip evenly, release smoothly, and avoid damaging string. Frequent stringers may benefit from a sturdier specialist model, while an occasional stringer may be satisfied with a less expensive clamp that passes those checks.
Final Thoughts
A tennis stringing starting clamp is a small tool that adds useful flexibility to a stringing setup. Choose one with clean, even jaws and a spring that holds securely without crushing the string. Whether you pick a Gamma, Tourna, Stringway, Babolat, or Pro’s Pro model, inspect it before use and treat it as a helper—not a substitute for sound stringing technique.
