Cabinet hinges are critical components for ensuring smooth door operation in furniture and cabinetry. Identifying the correct hinge type is essential for replacements or repairs. Here’s a step-by-step guide to accurately determine your cabinet hinge model.
Step 1: Locate the Series Number
Most modern hinges feature a stamped series number on the underside of the hinge cup (the circular part attached to the door) or the baseplate (mounted to the cabinet frame). These alphanumeric codes, such as “H3127” or “SG-9,” are key to identifying the hinge’s specifications.
- Pro Tip: Use a flashlight and magnifying glass to inspect hard-to-see areas.
Step 2: Match the Hinge Type
Hinges vary by design, including overlay, inset, and concealed styles. Measure the door’s overlay (the distance it covers the cabinet frame) and compare it to industry standards:
- Full Overlay: 1.5″ (38mm)
- Half Overlay: 0.75″ (19mm)
- Inset: 0mm (door sits flush with the frame)
Step 3: Verify Compatibility
Check screw hole alignment and hinge dimensions. Common specifications include:
- Cup Diameter: 35mm (standard) or 26mm (compact).
- Opening Angle: 90°, 110°, or 165° (for soft-close mechanisms).
Step 4: Consult Manufacturer Charts
Brands like Blum, Salice, and Hettich provide online catalogs. Input your series number to access technical drawings, load capacities (e.g., 20kg per hinge), and installation guidelines.
Why Accuracy Matters
Mismatched hinges can cause misalignment, wear, or door sagging. Over 70% of cabinet malfunctions stem from incorrect hinge installation, leading to costly repairs.
