Drawer slide, load capacity up to 45 kg, with ball bearing, 550 mm extension, 10 pairs (20 pieces)

【Industrial Solid Steel Ball Bearings for Superior Weight Support】The drawer slide rail is designed with two sets of internal ball bearings, all made with solid steel balls. In addition to maintaining the slide rail's mobility, it effectively increases the slide rail's load capacity. The full-extension drawer slides allow access to the entire space, and the drawers can be fully extended for easy storage. 【Rustproof, Long Lifespan】The surface of the rail undergoes an electrophoretic blackening process, which isolates it from direct contact with water and air to prevent oxidation and rust and improve corrosion resistance. More than 100,000 opening and closing tests have been carried out to verify its durability, and the normal lifespan of the sliding rail is over 30 years. 【Full Extension Slides】Full extension slides allow access to the entire space, and drawers can be fully extended for easy storage.
