HBF BI-FOLD LIFT MECHANISM 11-13 LBS is a Sugatsune America lift assist mechanism designed for upward-opening flap doors, so flap fronts on wall cabinets or overhead compartments rise smoothly instead of dropping. The built-in lift assist makes flap doors feel lighter, which reduces effort when opening heavier fronts in the 11-13 lbs range and helps users handle doors comfortably over repeated use. A free stop function holds the flap at any angle from 50 degrees to fully open, so the door stays where it is set and clears the work area while remaining accessible. Integrated soft-closing slows closing speed between 0 degrees and 40 degrees, which helps prevent slamming against the cabinet and supports a controlled, quiet close on every cycle. The mechanism belongs to the lid supports and stays class, so it plays the primary supporting role in an overhead flap assembly.
This bi-fold lift assist mechanism is intended for upward-opening flap doors, so the installation layout aligns with flap-style front construction. Opening angle is easy to adjust, allowing the installer to tailor how far the flap lifts to match the cabinet design and user reach. The mechanism must be used together with a concealed hinge with an appropriate opening degree, so the hinge geometry and the lift action work in the same opening range. A vertical adjustment function on the mounting plate at the flap side supports fast installation by allowing fine-tuning of the flap position after mounting, which helps align reveals and motion without relocating the main body. Installation uses a template specified by the manufacturer, simplifying layout of drilling positions and helping keep multiple doors consistent across a run.
This Sugatsune America bi-fold lift assist mechanism is designed for upward-opening flap doors, so it suits wall cabinets, overhead storage, and other applications where doors need to pivot upward and clear the workspace. The specified 11-13 lbs range defines the door weight this mechanism is intended to support, aligning lift performance with typical bi-fold flap constructions in that load band. The mechanism functions as part of a lift system and lid support assembly within the broader category of lift systems, lid supports, and stays, so it becomes the primary motion component controlling the flap while the concealed hinge governs pivot geometry. Because it is a bi-fold lift assist, it integrates into facades that open in a folding motion, which supports contemporary cabinet designs that prioritize overhead access without swing-out doors.
The combination of lift assist, free stop, and soft-closing in one mechanism directly affects day-to-day cabinet use, because the flap both rises with less effort and settles without sudden impact. Lift assist makes the door feel lighter throughout its travel, supporting controlled opening even when the user stands below an overhead unit. The free stop feature that holds any angle from 50 degrees to fully open reduces unintended movement, so the flap stays where it is positioned during tasks and does not drift downward into the work zone. Soft-closing that operates between 0 degrees and 40 degrees slows the final part of the closing arc, which helps protect both the door edge and cabinet face from repeated slamming and supports a predictable closing feel. Successful completion of 30,000 open and close cycles in a private test indicates these motion functions were exercised repeatedly, which is important when specifying hardware for installations expecting frequent daily use. The vertical adjustment function on the flap mounting plate improves setup by allowing incremental alignment changes after fastening, which supports consistent reveals across multiple doors and reduces the need for re-drilling. Using the mechanism with a concealed hinge matched to the required opening degree keeps the flap travel, opening angle, and lift support working in one coordinated motion path.
The bi-fold lift assist mechanism is designed for upward-opening flap doors, so it fits cabinet fronts that pivot upward rather than swinging sideways.
The bi-fold lift assist mechanism is specified for 11-13 lbs doors, which aligns lift assist performance to flap fronts built within that weight range.
The free stop function holds the flap door at any angle from 50 degrees to fully open, allowing the user to leave the door positioned where it is most convenient.
The soft-closing feature slows closing speed between 0 degrees and 40 degrees, which helps prevent the flap from slamming against the cabinet and supports controlled closing.
The bi-fold lift assist mechanism has an easy-to-adjust opening angle, so the installer can set how far the flap opens to suit the cabinet layout and user reach.
The vertical adjustment function on the mounting plate at the flap side allows fine-tuning of flap position after mounting, supporting accurate alignment without remounting the body.
This Sugatsune America bi-fold lift assist mechanism, part number HBF-ELAN-HM, is tailored to upward-opening flap doors in the 11-13 lbs range, so it aligns with many overhead cabinet fronts requiring smooth, assisted motion. Lift assist, free stop from 50 degrees to fully open, and soft-closing between 0 degrees and 40 degrees work together to deliver controlled, user-friendly movement in daily use. The easy-to-adjust opening angle, vertical adjustment on the flap mounting plate, and concealed-hinge-based layout provide practical setup flexibility for installers aiming for consistent reveals and motion. For projects calling for a tested lift system that has successfully passed 30,000 open and close cycles in a private test, this bi-fold lift assist mechanism offers a focused solution for flap-style installations.
