Phyfalip Heavy Duty Drawer Slides 3 Fold Full Extension Locking Side Mount Rails 12 to 40 Inch Pair Load Capacity 250 lb Corrosion Resistant

The drawer slides are crafted from high - density, high - strength Q235 industrial - grade cold - rolled steel and industrial solid steel balls, having undergone 150,000 push - pull tests without damage, with a maximum load capacity of up to 250 lb that varies according to the slide length, ensuring long - lasting durability for at least 30 years.

Equipped with a blue handle for locking and unlocking, the slides automatically hold still when fully extended or fully closed to prevent casual sliding and keep the drawer stable and safe, and by gently pressing the lock handle, it unlocks for free sliding and can be detached by holding the handle and pulling outward.

Featuring 3 - fold full extension, the drawer can be pulled out completely for easy access to the entire drawer, and with two rows of high - quality solid steel balls inside, it operates smoothly even when fully loaded, making the act of opening the drawer comfortable.

The slides have superior rust resistance compared to others due to the special galvanized blue sealing surface treatment, ensuring long - term use in various environments without corrosion.

When installing, choose the rail size according to the drawer depth with the drawer length greater than or equal to the slide length and a tolerance of 0.7in/20mm - 1in/30mm, and maintain a 19mm/0.75in space between the drawer and the cabinet wall on each side.

One set includes a pair of slides without screws, and M5 screws are applicable; you can purchase different M5 screws according to specific application scenarios, and if you encounter any installation problems, you can contact for assistance.
