It guarantees smooth operation and reliable locking, even with frequent use, outdoors, or under heavy loads. Its precision engineering and smooth tactile feel make it ideal for apparel and accessories demanding superior functionality and quality. In addition, TRC auto-lock slider (plastic) combines structural robustness with a clear and functional aesthetic and is therefore suitable for a wide range of applications, including sportswear, leisurewear, children's clothing, luggage and multipurpose equipment. We guarantee that each slider undergoes rigorous testing protocols, including testing for locking strength, durability, and colorfastness, to ensure lasting strength and consistent performance over extended use.

Quality Advantage：

TRC pullers are made of high-strength zinc alloy. This material gives them a stable structure even with frequent and prolonged use, prevents deformation and cracking, and ensures excellent durability and optimal corrosion resistance. Each puller is precision-made using CNC die casting. This process guarantees tight dimensional tolerances, ensuring perfect compatibility with various zipper sliders and tapes, thus reducing the risk of jams and improving the smoothness and reliability of the entire system. The surface of TRC pulls is polished, electroplated, or painted. This results in a smooth, clean surface that won't irritate clothing or skin. It also offers excellent colorfastness and high abrasion resistance, significantly extending the product's lifespan.
