Upgrade your cabinet storage with these heavy duty undermount drawer slides, designed for smooth movement, reliable support, and convenient access to stored items. Built from carbon steel with a three-stage full-extension mechanism, these drawer rails support loads up to 260 lbs while allowing drawers to extend fully for easier access. The ball bearing system and built-in silencer help minimize noise, making these slides a practical choice for under-stair cabinets, storage drawers, and DIY replacement projects.

Key Features

• 260 LB Load Capacity: Heavy-duty carbon steel construction supports loads up to 260 lbs. The galvanized steel plate provides corrosion and rust resistance, while the design has undergone 10,000 dynamic load tests.

• Three-Stage Full Extension: Allows drawers to extend fully, improving visibility and access to items stored toward the back compared with two-stage drawer slides.

• Smooth and Quiet Operation: Steel ball bearings and a high-quality spring provide stable sliding movement, while an integrated silencer reduces noise during opening and closing.

• Versatile Size Options: Available in four nominal lengths—16, 24, 32, and 40 inches—to accommodate different cabinet configurations and replacement needs.

• Practical Installation Design: Suitable for under-stair cabinet applications. Ensure sufficient clearance between the cabinet bottom and drawer, and select a slide length no greater than the cabinet body length.
