Locking Drawer Slides, 52 in Full Extension, 500 lb Pair

Heavy duty locking drawer slides keep large drawers stable and secure with a dual-lock system for travel, workshops, and industrial storage. Built from thick, high-hardness steel with a galvanized finish, these full extension ball bearing slides deliver smooth, quiet movement and access to the entire drawer. Ideal for cabinets, shelving, tool storage, RV builds, trucks, and vending equipment where load strength and controlled opening matter.

• Delivers up to 500 lb load capacity for heavy drawers, equipment trays, and storage modules.


• Locks securely with a double-lock design to help prevent slide-out on bumps and inclines.


• Glides smoothly with double-row ball bearings and nylon cushioning for quieter open/close action.


• Extends fully with a 3-fold full-extension design for easy reach to the back of the drawer.


• Fits side-mount installs; measure drawer depth first so slide length is not ≥ drawer depth.

Upgrade builds that can’t risk shifting cargo or hard-to-reach storage. These telescoping side mount drawer slide rails combine high load support with a positive locking latch, making them a practical choice for mobile drawers and high-use shop drawers. Use them in cabinets, industrial drawers, RV compartments, truck storage, or custom shelving where durability and controlled access are priorities. Confirm your drawer and cabinet measurements (excluding face frame boards) before ordering to ensure proper clearance and extension. Grab yours today and finish your heavy-duty drawer setup with confidence.
