- Product Introduction
A premium rail fastening component, the Professional SKL Clip is made to create strong, robust, and long-lasting connections between the sleeper and the rail. The SKL clip reduces vibration, noise, and track deformation by ensuring that rails stay securely in place under dynamic train loads as part of a comprehensive rail fastening system.
The Professional SKL Clip is made by Wuxi Lanling Railway Equipment Co., Ltd. using precision forging and heat treatment techniques on premium spring steel. It is perfect for heavy-duty and high-speed railway applications because of its exceptional flexibility, fatigue resistance, and corrosion protection.
