Locking drawer slides deliver secure, full-extension access for heavy drawers in garages, trucks, RV builds, and industrial cabinets. Built from thick, high-hardness steel with a galvanized finish, this side-mount slide pair supports up to 500 lb when closed and locked, helping keep tools and equipment from shifting on bumpy roads. Double-row ball bearings and nylon cushioning provide smooth travel with reduced noise.

• Delivers 3-fold full extension to access the entire drawer without blind spots.


• Locks securely with a double-lock press design to help prevent slide-out during transport.


• Supports heavy loads up to 500 lb capacity (200 lb when fully extended).


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


• Fits side-mount installations for cabinets, shelving, industrial drawers, RVs, trucks, and vending machines.

Upgrade storage where standard rails flex, stick, or drift open. These telescoping drawer slide rails are designed for stability under load and controlled opening/closing with a positive lock. Measure your drawer depth (excluding face frame/boards) before ordering, and choose a slide length shorter than the drawer depth for proper fit. Install with the correct alignment to get full travel and reliable locking. Grab yours today and build a drawer that stays put and pulls out smoothly when you need it.
