- Purpose and benefit Protects badminton rackets from cracking caused by high tension during the stringing process by distributing pressure over a larger area. - Design features Ribbed line design provides improved grip and control during handling and setup; the increased contact area helps spread pressure more evenly. - How it works Bat up and down during stringing to guide and stabilize the racket, reducing stress points at the frame. - Performance impact Helps prevent frame damage during high-tension restringing and supports a smoother, more reliable stringing workflow. - Use scenarios 1) Re-stringing a badminton racket at high tension in clubs or professional settings. 2) Servicing frames that are prone to cracking under concentrated pressure. 3) Routine maintenance in workshops where multiple rackets are serviced. - Compatibility and usage notes Designed for badminton rackets during stringing operations. Suitable for common racket shapes; no model-specific claims. - Material and size Not specified in the provided information.
