4. Installation
This section outlines the steps for installing the Blum Compact 33 Hinge on face frame cabinets. Ensure you have the necessary tools: a screwdriver, a drill (if pre-drilling is required), and a measuring tape.
4.1 Prepare the Cabinet Door
- Bore Hole for Hinge Cup: The Blum Compact 33 Hinge requires a 35mm diameter bore hole for the hinge cup. This hole should typically be drilled 3mm from the edge of the cabinet door. If replacing existing hinges, ensure the new hinge cup fits the existing bore hole.
- Positioning: Place the hinge cup into the bore hole on the cabinet door.
- Secure Hinge Cup: Use the provided #6 x 5/8 inch screws to secure the hinge cup to the cabinet door. Ensure the hinge is flush and securely fastened.

4.2 Attach Hinge to Cabinet Face Frame
- Position Door: Hold the cabinet door in its closed position against the cabinet opening. Ensure proper alignment.
- Mark Screw Locations: With the door correctly positioned, mark the screw locations for the hinge arm on the cabinet face frame. The hinge is designed for face mount applications.
- Pre-drill (Optional but Recommended): For hardwoods, pre-drilling small pilot holes can prevent wood splitting.
- Secure Hinge Arm: Use the remaining #6 x 5/8 inch screws to firmly attach the hinge arm to the cabinet face frame.

5. Adjustment
After installation, minor adjustments may be necessary to ensure proper door alignment and operation. The Blum Compact 33 Hinge allows for two types of adjustments:
- Height Adjustment: The hinge provides a height adjustment range of ±9/64 inches. This allows you to move the door up or down relative to the cabinet opening. Locate the appropriate screw on the hinge arm and turn it clockwise or counter-clockwise to achieve the desired height.
- Side Adjustment: A side adjustment of ±1/8 inch is available. This moves the door left or right, helping to achieve even gaps between doors or between the door and the cabinet frame. Identify the side adjustment screw and turn it as needed.
Adjustments should be made incrementally, checking the door's alignment after each turn until the desired position is achieved.
6. Maintenance
The Blum Compact 33 Hinges are designed for durability and require minimal maintenance. Regular care can extend their lifespan and ensure continued smooth operation.
- Cleaning: Wipe hinges periodically with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners or harsh chemicals, as these can damage the finish.
- Lubrication: Lubrication is generally not required for Blum hinges. If squeaking occurs, a small amount of silicone-based lubricant can be applied to the pivot points, but avoid over-lubricating.
- Inspection: Periodically check all screws for tightness. Loose screws can lead to door misalignment or hinge failure.
7. Troubleshooting
This section addresses common issues you might encounter with your Blum Compact 33 Hinges.
| Problem | Possible Cause | Solution |
