Hardware Resources Hinge - 3390 Series Collection

The Hardware Resources 3390 Series is an economical, standard-duty concealed European hinge with self-close action, designed for both face-frame and frameless cabinet builds. It is a 105-degree opening compact hinge whose cup sits fully hidden behind a closed door. Overlay options span 1/2-inch through 1-1/2-inch, making the same series compatible with full-overlay, partial-overlay, and inset-style doors.

The 3390 Series is the value tier in the Hardware Resources compact European hinge program and provides standard self-close action without a damper. The 8390 Series is the soft-close counterpart in the same catalog, adding a built-in damping mechanism that slows and cushions the door as it closes. Buyers who need a reliable, no-frills self-close hinge at a lower cost are served by the 3390; those who want whisper-quiet closing or are outfitting higher-end cabinetry typically choose the 8390.

Overlay refers to how far the door face extends over the cabinet opening when closed. The 3390 Series offers five overlay increments — 1/2-inch, 3/4-inch, 1-inch, 1-1/4-inch, and 1-1/2-inch — and selecting the wrong one will throw door alignment off across an entire cabinet run. Measure the actual door-to-opening overlap before ordering, and use the same overlay value consistently across a kitchen or bath project so door reveals stay even.

For replacement or retrofit work where holes are not machine-bored to 8 mm, the dowel-less or cleat version is the appropriate choice, as it mounts by screw directly into existing material without requiring precisely bored cup holes. The 8 mm press-dowel version is best suited to new production runs where a boring machine sets consistent hole locations. A four-way adjustment variant is also available and is particularly useful on older cabinetry where cabinet boxes may be slightly out of square, reducing setup time during dial-in.
