Nickel Concealed Hinge for Flush Inset Doors on Face-Frame and Frameless Cabinets

This Grass Tiomos concealed hinge is built for inset doors, placing the door flush inside the cabinet opening on both face-frame and frameless cabinets. Dowel mounting seats the hinge in the door with no cup screws, and a self-close spring draws the door shut automatically.

Key Features

• Inset full-crank geometry positions the door flush within the cabinet opening, with an even reveal on all sides.
• Self-close spring pulls the door shut over the last few degrees of travel without a separate closer.
• 110 degree opening provides standard everyday swing for inset cabinet access.
• Dowel mount presses into pre-bored dowel holes in the door, eliminating cup screws for a clean CNC-ready installation.
• Three-way adjustment dials height, depth, and side position after the door is hung.
• Works on face-frame and frameless cabinets when paired with the matching Grass Tiomos base plate.

Inset Doors That Sit Flush and Close on Their Own

An inset door lives inside the cabinet opening rather than overlapping it, so the geometry that seats the door correctly is what this hinge is built around. The full-crank arm carries that inset position, letting the door clear the opening as it swings while keeping the reveal even on all sides. The 35mm cup bores into the door back, and the arm connects to a Grass Tiomos base plate mounted to the cabinet, sold separately. Dowel mounting simplifies the door side of the install: the dowels press into pre-bored holes without cup screws, which makes it a natural fit for CNC shops running inset work at volume. The self-close spring handles the close, pulling the door home from a few degrees open.

Steel Build in Nickel

The hinge body is steel finished in nickel. Three-way adjustment covers plus or minus 3mm in height and side, and plus 3mm to minus 2mm in depth, which is enough range to bring inset doors to a consistent reveal after the cabinet is set and any seasonal movement has settled in. Maximum door thickness for this hinge is 24mm, covering standard and slightly thicker inset doors. The Grass Tiomos boring pattern runs at 42mm, which differs from the 45mm pattern used by other brands, so confirm this against your existing boring setup before ordering a replacement.

Who Reaches for This Hinge

This hinge suits cabinet shops and finish carpenters doing inset work on face-frame or frameless boxes, where a self-close mechanism is enough and a softer, damped close is not required. CNC production environments benefit from the dowel mount, since the press-in connection skips the cup-screw step and keeps the boring sequence consistent. For inset projects where a quiet, cushioned close is the goal, a Grass Tiomos soft-close inset hinge is the closer fit. For doors thicker than 24mm, move to a thick-door hinge in this series.

Inset Doors Done Clean, From the First Hinge to the Last

Specify this hinge when the project calls for inset doors that close automatically, install fast with dowel mounting, and hold their reveal across face-frame and frameless boxes alike.
