The Vevor heavy-duty drawer slides are designed for side-mount applications where strength, stability, and full access are essential. Built from high-hardness steel with a galvanized finish, they support demanding storage setups in cabinets, industrial drawers, RVs, trucks, and other commercial applications. The 3-fold full extension design helps you reach the entire drawer, while the locking mechanism keeps contents secure during movement. Double-row ball bearings and nylon cushioning promote smooth, quiet operation. This pair includes mounting hardware for convenient installation.
