48 Inch Locking Full Extension Drawer Slides, 500 lb Pair

Heavy duty locking drawer slides deliver full-extension access and secure hold for large drawers, tool storage, and vehicle builds. Built from 0.77 in (19.5 mm) thick high-hardness steel with a galvanized finish, these side-mount ball bearing slide rails are designed for smooth travel and reduced rattle. The press-to-lock mechanism helps keep drawers shut during movement—ideal for RVs, trucks, cabinets, shelving, and industrial drawers where stability matters.

• Delivers up to 500 lb load capacity for heavy drawers, equipment, and storage builds


• Locks with a press to keep drawers secured on bumpy roads and during transport


• Glides smoothly with double-row ball bearings for consistent open/close performance


• Reduces noise using nylon cushioning to help prevent bounce and harsh slam


• Fits side-mount installs in cabinets, shelving, RVs, trucks, vending machines, and shop drawers

Get reliable full-extension reach without sacrificing security. The 3-fold telescoping design lets you access the entire drawer, while the locking and latching action adds control when the drawer is extended or stored. For best fit, measure cabinet depth and drawer length (excluding face/frame boards) before ordering; slide length should be less than the drawer depth. Upgrade your build with stable, rust-resistant slide rails—grab yours today.
