• 【Bottom-Mounted Concealed Design】Maximize space utilization with this bottom-mounted concealed drawer runner, perfectly suited for under-stair cabinets, kitchen corner cabinets, and narrow storage areas. The undermount design hides the rails beneath the drawer, creating a refined, clutter-free appearance while freeing up valuable interior space for larger or oddly shaped items.
• 【High-Strength Steel & 120kg Load Capacity】Crafted from premium cold-rolled steel with a thickness of 2.0mm and a special electroplated coating, this heavy-duty drawer slide resists oxidation, rust, and corrosion. It supports an impressive load capacity of 120kg (265 lbs) without breaking or deforming, making it ideal for under-stair storage, large home cabinets, and kitchen systems.
• 【Full-Extension Three-Section Slide】Enjoy complete access to every corner of your drawer thanks to the 3-fold full-extension design—original length 15.75" (400mm) extends fully to 35" (900mm). This allows the drawer to be pulled out entirely, providing easy visibility and access to stored items, while leaving ample room for screw installation inside stair cabinets or deep storage units.
• 【Smooth & Quiet Operation】Equipped with double rows of high-quality solid steel ball bearings and a rear rubber mute pad, this ball bearing drawer slide ensures exceptionally smooth push-pull motion with minimal noise. Open and close your drawers effortlessly, enjoying a quiet, comfortable home experience even in bedrooms or living areas.
• 【Multi-Hole Fixing & Easy Installation】Scientific positioning hole design offers multiple secure fixing points, preventing the runner from loosening or falling off over time. Recommended for stair cabinet widths between 30–60cm with a reserved installation height of 53.8mm between cabinet and bottom plate.
