HBF BI-FOLD LIFT MECHANISM 9-11 LBS is a Sugatsune bi-fold lift assist mechanism designed for upward-opening flap doors, so it supports front panels that open up instead of swinging out. The built-in lift assist makes compatible flap doors feel lighter in motion, which reduces effort when opening and helps with smoother operation on frequently used cabinets. A free stop function holds the flap at any angle from 50 degrees to fully open, allowing the door to stay where it is moved without drifting. This controlled positioning supports comfortable access to contents while working in front of the cabinet. Integrated soft-closing slows the closing speed between 0 degrees and 40 degrees, reducing impact at the end of travel. That controlled closing action helps reduce stress on the door, hinges, and cabinet structure over repeated daily cycles.
This Sugatsune America lift assist mechanism is used together with a concealed hinge with an appropriate opening degree, so the flap door motion depends on both the lift unit and hinge geometry. Easy opening angle adjustment is built into the mechanism, allowing the maximum open position to be set so doors do not travel beyond the desired point. That opening angle control supports alignment with adjacent cabinets, ceilings, or over-shelf clearances in a run. Fast installation is supported by a vertical adjustment function on the mounting plate located on the flap, letting the door position be fine-tuned after the mechanism is fixed. Installation is described as simple when using the dedicated template, which standardizes hole locations for repeatable results across multiple cabinets.
This bi-fold lift assist mechanism is specified for upward-opening flap doors, so it is intended for front panels that pivot upward above the cabinet face. By targeting 9-11 lbs door weight, the unit is designed to balance that mass so opening feels assisted rather than heavy, which is useful on wider or taller fronts within that weight range. The free stop function that holds from 50 degrees to fully open lets the flap rest at partial or full height, which supports use above work surfaces where users may want a partially open position. Soft-closing that engages from 0 degrees to 40 degrees manages the last part of the closing stroke, which is the range where slamming typically occurs on flap doors. Together, these functions support controlled movement of the door through its full travel.
The easy opening angle adjustment allows installers to set how far the flap opens, translating into predictable clearances where doors must stay below ceilings, lights, or other upper elements. Because this mechanism must be used together with a concealed hinge with the appropriate opening degree, the combined hardware defines the door trajectory, which matters when aligning with surrounding cabinets. The vertical adjustment function on the mounting plate gives a way to refine the flap position after mounting, which helps align reveals and front heights without remounting components. Installation is described as simple when the template is used, so hole drilling and position layout can follow a consistent pattern across multiple units. The mechanism successfully passed 30,000 open/close cycles in a private test, indicating that the lift assist, free stop, and soft-closing functions were exercised repeatedly, which speaks to performance over extended use in normal cabinet operation.
The bi-fold lift assist mechanism is for upward-opening flap doors, so it supports front panels that pivot up above the cabinet face in wall or overhead applications.
The 9-11 lbs rating means the mechanism is designed to assist flap doors within that weight range, so the lift, free stop, and soft-closing functions operate as intended on those fronts.
The free stop function holds the flap from 50 degrees to fully open, letting the door stay at intermediate positions for easier access while working in front of the cabinet.
Soft-closing between 0 degrees and 40 degrees slows the final closing movement, which reduces slamming at the end of travel and helps limit impact on the cabinet.
The lift assist mechanism has an easy opening angle adjustment, so installers set the maximum open position to match clearances and alignment with nearby elements.
The mounting plate on the flap provides vertical adjustment, allowing fine-tuning of the door position after installation to align fronts and gaps.
The HBF-ELAN-MM bi-fold lift assist mechanism from Sugatsune America combines lift assist, free stop, and soft-closing in one unit for upward-opening flap doors. With a 9-11 lbs operating range, adjustable opening angle, and vertical adjustment on the mounting plate, it supports controlled motion and refined alignment on overhead fronts. For projects using concealed hinges with the appropriate opening degree, this mechanism provides a coordinated way to manage door movement through the full open and close cycle.
