Half Overlay Soft-Close Hinge for Shared Partitions and Double-Door Cabinets

The Grass Tiomos Impresso is a concealed soft-close hinge built for half overlay doors on both face-frame and frameless cabinets, including pairs of doors that share a single center partition.

Key Features

• Integrated soft-close damper slows the door over the final closing arc so it settles quietly without slamming.
• Half overlay, half crank arm positions the door at a partial overlay, the correct geometry for two doors sharing one partition.
• 110 degree opening angle delivers standard everyday cabinet access.
• Toolless snap-on mounting clips the arm to the base plate without tools for fast door hanging and removal.
• 42/45mm dual boring pattern accommodates Grass-standard and common legacy bore spacing on existing cabinet boxes.
• Three-way adjustment moves the door up to 3mm in height, depth, and side for precise reveal alignment after install.

The Right Geometry for Shared-Partition Doors

Half overlay is the configuration where a door covers roughly half the cabinet side rather than the full panel, most often when two doors meet on a single center partition. Each door needs a half crank arm so both arms clear the partition without colliding. This hinge is built for exactly that condition, on frameless box construction and face-frame cabinets alike. The 35mm cup bores into the back of the door, and the arm snaps to a Grass base plate mounted on the cabinet. That plate is a separate item, matched to your cabinet construction and ordered from the Grass plate range.

Tiomos Build and Nickel Finish

The Tiomos Impresso is steel with a nickel finish. The Grass Tiomos platform is built for production environments where hinges are installed, adjusted, and occasionally removed at volume. The snap-on arm engagement handles that cycle cleanly. Soft-close is integrated into the hinge body rather than added as a clip-on adapter, so the damping is consistent across every door and there are no extra parts to source separately. The three-way adjustment range keeps doors square as cabinets settle over time.

Who Specifies This Hinge

Cabinet shops running double-door uppers and base cabinets reach for this hinge when the design calls for half overlay doors and a quiet, damped close. It suits face-frame and frameless boxes, so it works across mixed production runs. The 42/45mm dual bore pattern covers the Grass-standard spacing and aligns with many existing line-bore setups, which makes it a workable option for renovation work replacing hinges in already-bored doors. For doors up to 24mm thick, this hinge fits the standard range. For full overlay doors, choose the full overlay Tiomos variant instead.

Quiet Double Doors, Lined Up Clean

Specify this hinge when the job calls for half overlay doors that close quietly, sit square on their partition, and come off and on quickly during finishing and install.
