Nickel CLIP top Half Overlay Hinge Built for Wide-Clearance Doors

The Blum CLIP top 71T6680 is a concealed half overlay hinge that opens to 170 degrees, giving near-flat door clearance on face-frame and frameless cabinets. The hinge uses a dowel mount for press-in CNC installation and a self-closing spring to pull the door shut.

Key Features

• 170 degree opening angle swings the door nearly flat, maximizing access in appliance garages, corner units, and tight spaces.
• Half overlay, half crank arm positions the door for partial overlay, including two doors sharing a single center partition.
• Self-closing spring draws the door shut over the final degrees of travel.
• Dowel mount cup presses into pre-bored dowel holes for fast, screw-free door-side installation in CNC and production workflows.
• Three-way adjustment dials in height, side, and depth after hanging to bring doors to an even reveal.
• 35mm cup, 45mm bore pattern fits standard door boring on 16 to 22mm doors.

Where the Wide Swing Earns Its Place

Most concealed hinges open to 110 degrees, which suits everyday cabinets. The 170 degree opening is a different tool: it lets a door swing until it sits nearly parallel to the cabinet side, which matters in tight kitchens where a door at 110 degrees would block the aisle, in appliance garages where the door needs to tuck out of the way, and in corner or peninsula layouts where adjacent cabinetry limits working space. The half crank positions the door at a partial overlay, making this hinge the correct pick when two doors share a center partition or when the design calls for less than a full cover on the cabinet side.

The 35mm cup bores into the back of the door at standard 45mm bore spacing. The arm clips to a Blum base plate mounted to the cabinet, which is ordered separately. Match the plate to your cabinet construction and the overlay you need.

Steel Build in a Nickel Finish

The hinge is plated steel in a nickel finish, consistent with the CLIP top line's standard construction. At this opening angle the self-closing spring does the closing work without a damper, so the closing feel is a firm, spring-pulled shut rather than a cushioned settle. Three-way adjustment stays accessible after installation: the cam screws move the door plus or minus 2mm in height and side, and 3mm forward or 2mm back in depth, so doors can be squared up after the cabinet is installed.

Production Shops and CNC-Ready Workflows

The dowel mount is built for shops where doors are bored on a CNC and assembled without picking up a screwdriver at the cup. The dowels press into pre-bored holes and lock the cup in position, which keeps a production line moving. For frameless and face-frame boxes alike, the CLIP top arm clips to the base plate without tools, so hanging a door is still a one-person step. This hinge suits cabinet shops running volume on standard doors, contractors who need a wide-swing option for a specific layout problem, and builders specifying half overlay across a run of face-frame or frameless boxes.
