3. Setup and Installation
The Kolbe Korners are designed for straightforward installation. Follow these steps to attach drawer fronts or bottoms securely:
- Prepare Components: Ensure your drawer box and drawer front/bottom are clean and free of debris. Identify the desired mounting locations for the Kolbe Korners.
- Position the Korner: Place a Kolbe Korner at the desired attachment point, typically on the inside corner of the drawer box where it meets the drawer front or bottom. The slotted holes should align with the direction of adjustment needed.
- Secure to Drawer Box: Using appropriate screws (not included), fasten one flange of the Kolbe Korner to the drawer box. Do not overtighten initially, allowing for minor adjustments.
- Attach Drawer Front/Bottom: Align the drawer front or bottom with the drawer box. Fasten the second flange of the Kolbe Korner to the drawer front or bottom using screws.
- Adjust Alignment: Utilize the slotted holes to make fine adjustments to the position of the drawer front or bottom. Slide the component until it is perfectly aligned.
- Final Tightening: Once alignment is satisfactory, fully tighten all screws to secure the Kolbe Korners in place.
4. Operating Instructions
The Kolbe Korners function as fixed mounting brackets once installed. Their primary 'operation' involves the initial adjustment phase during installation:
- Post-Installation Adjustment: If minor adjustments are needed after initial installation, slightly loosen the screws securing the Kolbe Korner, reposition the drawer front/bottom using the slotted holes, and then re-tighten the screws.
- Removal: To remove a drawer front or bottom, simply unscrew the Kolbe Korners from both the drawer box and the attached component.
5. Maintenance
FastCap Metal Kolbe Korners require minimal maintenance due to their durable metal construction.
- Cleaning: If necessary, wipe the corners with a dry or slightly damp cloth to remove dust or debris. Avoid abrasive cleaners.
- Inspection: Periodically inspect installed Kolbe Korners for any signs of loosening screws or damage. Tighten screws as needed.
- Storage: Store unused Kolbe Korners in a dry environment to prevent corrosion.
6. Troubleshooting
Most issues related to Kolbe Korners can be resolved with simple adjustments.
- Drawer Front/Bottom Not Level:
Solution: Loosen the screws on the Kolbe Korners slightly. Adjust the drawer front/bottom up or down using the slotted holes until level. Re-tighten screws. - Drawer Front/Bottom Not Flush:
Solution: Ensure the Kolbe Korners are fully seated against both the drawer box and the drawer front/bottom. Check that screws are tightened securely. If the issue persists, verify the dimensions of your drawer components. - Screws Stripping:
Solution: Use screws of appropriate length and diameter for your material. Avoid overtightening. If a hole is stripped, consider using a slightly larger screw or a wood filler to repair the hole before re-inserting the screw.
