40 in Locking Full Extension Drawer Slides, 500 lb Pair

Locking drawer slides keep heavy drawers secure while delivering smooth, full-extension access for tools, gear, and storage. This side-mount, 3-fold telescoping rail set is built from thick, high-hardness steel with a galvanized finish to resist rust and wear in workshops, RVs, trucks, cabinets, and industrial drawers. Double-row ball bearings and nylon cushioning help reduce noise and bounce for controlled opening and closing.

• Delivers up to 500 lb load capacity for heavy-duty drawers, slide-outs, and equipment trays


• Locks securely with a simple press to prevent unwanted movement on bumpy roads or mobile setups


• Extends fully with 3-fold travel so you can reach the entire drawer without blind spots


• Glides smoothly with double-row ball bearings and nylon cushioning for quieter, steadier motion


• Fits side-mount installations in cabinets, shelving, RVs, trucks, vending machines, and shop builds

Built for demanding storage builds where stability matters, these full extension drawer slide rails combine high load strength with a positive locking latch for safer transport and everyday use. Measure your drawer depth (excluding face frame/boards) before ordering; the slide length should be less than the drawer depth for proper fit and operation. Upgrade a sagging drawer, add a locking slide-out tray, or reinforce a tool drawer with confidence. Grab yours today and get your next build moving smoothly and staying put.
