The Vevor 24" full-extension drawer slides are built for heavy-duty storage applications with a 500 lbs load capacity. Made from high-hardness steel with a galvanized finish, they are designed for durability, rust resistance, and smooth operation. A locking mechanism helps keep drawers securely in place, while double-row ball bearings and nylon cushioning support quiet, controlled movement. These side-mount slides are suitable for cabinets, industrial drawers, RVs, trucks, and vending machines. The package includes one pair of slide rails with installation hardware.
