Heavy Duty Locking Drawer Slides 34 in Full Extension - 150 lb

In this review of the 1 Pair Heavy Duty Locking Drawer Slides (34 in) the bottom line is clear: these slides are for anyone who needs a strong, full extension slide with a secure locking feature for heavy drawers or equipment. The reviewer found the single biggest reason to buy is the combination of a 150 lb rated capacity with a reliable locking mechanism that secures the drawer when fully closed or fully open, making them especially useful in mobile or industrial settings where movement or vibration is a concern.

Key Features

• Locking mechanism: A simultaneous press on the black handles locks or unlocks both slides to prevent unintended movement when the drawer is fully closed or fully open.
• Heavy load capacity: The rails are rated to support up to 150 lb, suitable for tool drawers, equipment racks, or heavy storage.
• Durable construction: All three sections use 1.5 mm thick Q235 steel and cold-rolled steel for long service life and resistance to deformation under load.
• Corrosion resistance: The galvanized blue sealing finish increases oxidation and corrosion resistance for longer outdoor or mobile use.
• Full extension: Full extension ball bearing design provides complete access to drawer contents for easier organization and retrieval.
• Long cycle life: Tested to more than 150,000 open/close cycles, indicating a durable mechanism for repeated use.

Who It's For

These locking drawer slides suit homeowners fitting heavy cabinetry, hobbyists building tool storage, and professionals refitting RVs, trucks, or vending machines where a secure, full-access drawer is required. The locking feature makes them particularly useful for mobile applications where vibration could cause drawers to open.

Those who need integrated or specialized fasteners should note that only eight M4 screws are included and you may need to source additional or different-length screws for your specific installation. If you require a concealed undermount slide or soft-close action, this product is not the right choice.
