1. Installation Note: The clearance between the drawer and the cabinet wall must be 1.9 cm on each side (left and right), totaling 3.8 cm (internal cabinet width – external width 3.8 cm). Note: For installation. 2. Maximum Load Capacity: The slides are made of 2 mm thick, density coldrolled steel sheet (tensile strength > 400 MPa), ensuring your drawers remain stable and secure even when carrying items weighing up to 117.9 kg. They can withstand 150,000 openandclose cycles without damage. Note: The shorter the slide, the greater the weight load. 3. Equipped with a locking mechanism and removable handle. A blue handle is provided for locking and unlocking. When fully extended or fully closed, the slides automatically lock (in the locked state), preventing accidental sliding and keeping your drawer stable and secure. Gently press the locking handle to release it and slide . Removable: By pressing and holding the lock handle, the third rail (the narrowest section) can be detached. 4. 3Stage Full Extension Slide width: 53 mm, maximum load capacity: 120 kg. The '3stage full extension' allows the slides to be fully extended, enabling the drawer to be completely pulled out for easy access to the entire storage space.
