Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your drawer slides. Please follow these steps carefully.
Pre-Installation Checks
- Slide Length: The slide length is 20 inches (500 mm).
- Fully Extended Length: The slides extend to 40 inches (1000 mm).
- Drawer Depth: Ensure your drawer has an internal depth of at least 20-22 inches.
- Clearance: A space of 0.5 inches (12.5 mm) is required between the drawer and the cabinet wall on both the left and right sides. This means the internal cabinet width minus the external drawer width should equal 1 inch (25 mm).

Installation Steps
- Separate the Slides: The drawer slides consist of three parts. Gently pull the inner rail until it detaches from the middle rail. There is a small plastic buckle at the back of the slide that allows for separation. Press this buckle to release the inner rail.
- Mount Inner Rails to Drawer: Attach the narrower inner rails to the sides of your drawer using the provided screws. Ensure they are flush and level.
- Mount Outer Rails to Cabinet: Attach the wider outer rails to the inside of your cabinet opening. Use a level to ensure they are perfectly horizontal and parallel to each other. Maintain the 0.5-inch clearance on each side.
- Insert Drawer: Align the inner rails on the drawer with the middle rails on the cabinet. Gently push the drawer into the cabinet until the slides engage. You should hear a soft click as the plastic buckle locks into place.
- Test Operation: Slowly open and close the drawer to ensure smooth movement and full extension. Adjust if necessary.

Operating Instructions
These drawer slides are designed for simple and reliable operation.
- Opening the Drawer: Pull the drawer handle to open. The three-fold full extension mechanism allows the drawer to slide out completely, providing full access to items stored at the back.
- Closing the Drawer: Push the drawer gently to close. The ball bearings ensure a smooth and quiet return. The rubber bumper pad helps absorb impact and reduces noise upon closing.
- Detaching the Drawer: To remove the drawer from the cabinet, fully extend the drawer. Locate the plastic buckle at the back of each slide (typically on the inner rail). Press the buckle (usually downwards for one side, upwards for the other) and pull the drawer forward to detach it. This is useful for cleaning or accessing the cabinet interior.
Maintenance
Regular maintenance ensures the longevity and smooth operation of your YENUO drawer slides.
- Cleaning: Wipe the slides periodically with a clean, damp cloth to remove dust and debris. Avoid abrasive cleaners.
- Lubrication: While the ball bearings are designed for long-term smooth operation, a light application of silicone-based lubricant (avoid oil-based lubricants as they can attract dust) can be applied to the moving parts if you notice any stiffness over time.
- Inspection: Periodically check all mounting screws to ensure they are tight. Loose screws can affect performance and stability.
- Load Capacity: Do not exceed the maximum load capacity of 100 lbs (45 kg) to prevent damage to the slides and drawer.
