Why Upgrading Your Stringing Clamps Matters
Using outdated, low-quality clamps completely compromises the tension integrity of your racquet and destroys expensive strings. Poorly engineered clamps lead to immediate tension loss and dangerous string slippage. More critically, imprecise grip jaws increase the risk of crushing delicate multifilament strings, causing premature on-court breakage.
Self-Aligning Biangular Tech
The Claws 3.0 feature patented technology that self-aligns to all string types, keeping them perfectly parallel for exact tension accuracy.
Multi-String Capability
Our advanced flying clamps distribute clamping pressure evenly, easily handling two or three strings simultaneously to speed up your workflow.
Double Flying Clamp Speed
For stringers tired of being chained to a heavy, clunky stringing machine clamp base, our double flying clamp system provides unmatched maneuverability.
Premium Adjustable Knobs
Easily dial in the perfect clamping force. Use firmer pressure for slick co-poly, or soften the grip to protect delicate natural gut strings from crushing.
Main and Cross String Agility
Portable flying clamps allow you to seamlessly transition between main and cross strings without the restrictive tracking rails of fixed base clamps.
Starting Clamp Security
A heavy-duty starting clamp is an absolute must-have tool for starting mains and securing high-tension tie-off knots without crimping.
Electronic Tensioner vs Drop-Weight Compatibility
When using an electronic constant-pull tensioner, the machine actively micro-adjusts the string during the pull. If you are using cheap, inferior clamps, the string will slowly slip through the teeth, completely negating the precision of your electronic machine. This is a common issue for users transitioning away from entry-level drop-weight or manual crank stringers.
PRO STRINGER aluminum flying clamps are explicitly engineered to match the extreme accuracy of electronic tensioners. By selecting the correct clamp type (Claws vs Badminton Clamp) and adjusting the tension knob, you guarantee that the constant-pull accuracy makes it directly into the final string bed without any tension loss or permanent string deformation.
Frequently Asked Questions
What is the difference between Claws and Badminton clamps?
The primary difference is the tooth spacing. Our Claws (2.0 and 3.0) feature wider spacing designed for tennis and squash strings, while the Badminton Clamp uses micro-tooth spacing to securely grip ultra-thin strings (0.61mm-0.68mm) without slippage.
Are double flying clamps as accurate as a fixed stringing machine clamp base?
Yes. While fixed base clamps are stationary on a track, premium flying clamps like our Claws 3.0 provide superior mobility and self-aligning technology, allowing you to clamp main and cross strings perfectly parallel across the racquet head without compromising tension.
Why do I need a specialized starting clamp for knot tying?
Starting clamps use a heavy-duty spring mechanism to act as an extension of the string and hold high tension outside the frame. This prevents the string from pulling back through the grommet, securing tie-off knots perfectly without crimping.
How do I adjust the clamping pressure for co-poly versus natural gut?
Use the adjustable knob on the Claws to actively modulate pressure. Slick co-poly strings require firmer pressure to prevent sliding through the teeth, whereas natural gut and soft multifilament strings require a lighter touch to avoid permanent deformation and crushing.
How can I stop my stringing clamps from slipping or crushing strings?
Always clean the teeth of your clamps with rubbing alcohol to remove string wax buildup. Then, identify the optimal pressure by incrementally tightening the adjustable knob until the string stays perfectly secure without flattening. If crushing occurs, reduce pressure; if slipping occurs, increase it.
Trusted by Thousands of Players
Hear from top ATP & WTA players who trust Pro Stringer for their tournament preparation
I bought mine on the internet a few years ago with my dad's help. I use Pro Stringer when I'm at home because paying for two new strings a day is too much. Brought it with me on my challenger tour. It’s very easy to use... I just read the instructions and now string in under 20 minutes!
"This is a legit stringer, it just works! A consistent string job every time for my players. What more do you want? Our USC players traveled all through Europe for 6 weeks with 2 of the machines… we did not have to hunt down a shop to get some random tensions in the rackets."
It's a great machine, no doubt. I have had it for many years, and I still use it when I'm training in Brisbane. The machine gives me consistent results when I'm overseas playing tournaments, and setting it up is easy.
I can’t believe how small Pro Stringer is and how perfectly it works for my rackets! Incredible technology!
The Blue Steel 1.28mm I developed with Pro Stringer is the best string on tour, and trust me, I’ve tried many strings. The feel and spin is second to none as well as the durability. With the snap-back ability it has a consistent response on every shot and my entire career is now based on it. Give it a try and I promise you won’t be disappointed.
