5. Installation Guide (Setup)

5.1 Pre-installation Checks

• Measure Cabinet Depth: Ensure your cabinet depth is between 19.3"-20.1" (490-510mm) for 18-inch slides.
• Measure Drawer Length: The drawer box length should be 18 inches (457mm).
• Side Clearance: Maintain a side clearance of typically 1/2" to 1" between the drawer box and the cabinet interior for optimal function.

5.2 Step-by-Step Installation

Refer to the following steps and the installation video for a visual guide.

1. Separate the Slides: The drawer slides consist of two main parts: the cabinet member and the drawer member. Gently pull the slide apart to separate them.
2. Install Rear Mounting Brackets: Attach the rear mounting brackets to the back of the cabinet interior using the provided screws. Ensure they are level and at the correct height.
3. Install Cabinet Members: Secure the cabinet members (the longer parts of the slides) to the cabinet sides. The front end of the slide should be flush with the front edge of the cabinet opening. Use the provided screws and ensure both sides are parallel and level.
4. Install Locking Devices: Attach the adjustable locking devices to the underside of the drawer box, near the front.
5. Install Drawer Members: Secure the drawer members (the shorter parts of the slides) to the bottom sides of the drawer box.
6. Insert the Drawer: Align the drawer members with the cabinet members and gently push the drawer into the cabinet. The locking devices on the drawer should engage with the front of the cabinet slides. Listen for a click to confirm engagement.
7. Adjust Drawer: Use the adjustment features on the locking devices to fine-tune the drawer alignment for a perfect fit and smooth operation.

6. Operation

Once installed, your Knobonly drawer slides provide smooth and quiet operation:

• Full Extension: Pull the drawer completely out to access all contents. The slides are designed to extend fully, offering approximately 15 inches (379mm) of pull-out length.
• Soft Close: To close the drawer, gently push it until the soft-close mechanism engages. The drawer will then slowly and quietly pull itself shut, preventing slamming and reducing wear and tear.

7. Maintenance

To ensure the longevity and smooth performance of your drawer slides, follow these simple maintenance tips:

• Cleaning: Periodically wipe down the slides with a clean, damp cloth to remove dust and debris. Avoid abrasive cleaners.
• Lubrication: The slides are pre-lubricated. If you notice any stiffness over time, a light application of a silicone-based lubricant can be applied to the moving parts. Avoid oil-based lubricants as they can attract dust.
• Check Fasteners: Occasionally check all mounting screws to ensure they are tight. Loose screws can affect performance and stability.

8. Troubleshooting

• Drawer does not close softly:
  • Check for obstructions in the slide mechanism or drawer path.
  • Ensure the drawer is not overloaded, exceeding the 85 lb capacity.
  • Verify that the soft-close mechanism is properly engaged and not damaged.
• Drawer is stiff or difficult to open/close:
  • Inspect the slides for dirt or debris and clean as per maintenance instructions.
  • Check if the slides are properly aligned and level. Misalignment can cause friction.
  • Ensure all mounting screws are securely fastened.
• Drawer wobbles or is unstable:
  • Confirm that the drawer box is correctly seated on the locking devices and fully engaged with the cabinet members.
  • Check for loose screws on both the drawer and cabinet members.
  • Verify that the drawer box itself is structurally sound and not damaged.
• Drawer does not fit or align correctly:
  • Re-check all measurements against the specifications in Section 4 and 5.1.
  • Utilize the adjustable locking devices to make minor adjustments to the drawer's position.
