20-Inch Locking Full Extension Drawer Slides, 500 lb Pair

Heavy duty locking drawer slides keep large drawers stable and secure while delivering smooth full-extension access. This pair of side-mount, ball bearing slide rails is built for demanding storage—workbenches, tool cabinets, industrial drawers, RV compartments, and truck builds—where standard slides flex or drift open. Dual locks help prevent accidental movement on uneven surfaces, while nylon cushioning reduces bounce and closing noise for a cleaner, controlled glide.

• Delivers 3-fold full extension so you can reach the entire drawer without fighting dead space


• Locks with a dual-lock mechanism to keep drawers closed and contents secured on bumpy roads


• Handles heavy loads up to 500 lb capacity (450 lb when fully extended) for tough builds


• Glides smoothly with double-row ball bearings plus nylon cushioning for quieter operation


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

Built from high-hardness steel with a galvanized finish, these full extension drawer slide rails are designed for long service life in high-use environments. Measure your drawer and cabinet depth (excluding face frames) before ordering; slide length should not be less than or equal to the drawer depth. If you need a secure, smooth-travel upgrade for a heavy drawer that must stay put, grab yours today and build with confidence.
