Lift Assist Mechanism 485 - 550 PSI is a Sugatsune America lift-assist mechanism designed for flap doors, so the door can open and stay positioned without separate lid supports. This lift-assist mechanism is built so the door opens over the cabinet, which lets the front move up and out of the way instead of swinging into the user space. A space of 4-5/16 inches is required over the cabinet, which defines how much clearance is needed when planning cabinet height relative to ceilings or obstacles. The mechanism is part of the lid supports and stays product class, so it supports the flap while controlling movement. The product is described as a lift-assist mechanism for extra light-opening, which reduces the effort needed to raise the flap door during frequent use. This model is identified by manufacturer part number EZS-ELAN-ML, which ties ordering and specification back to Sugatsune documentation on similar lift systems.
This lift-assist mechanism is described as having simple installation by aligning the body to the edge of the cabinet, which gives a straightforward reference line when setting the hardware location on new or existing casework. Because the door opens over the cabinet, the motion path takes the flap up and in front of the cabinet top, so the installer can plan clearance relative to walls, trim, or ceiling elements using the 4-5/16 inch space requirement. The product description specifies that no hinges or connecting bar are needed, which removes extra drilling and layout steps normally required for separate hinge sets on flap doors. Door height is adjustable horizontally plus or minus 3/64 inch and vertically plus or minus 5/64 inch, which allows fine tuning of gaps and alignment so the flap can be set even with adjacent fronts after mounting.
This Sugatsune America lift-assist mechanism is categorized under work surface and tables, lift systems, lid supports and stays, which positions it for applications where a flap door or lid needs controlled lifting and holding. The description states that the door opens over the cabinet, which suits upper storage areas where a front needs to move clear of the opening while providing access to the interior. Because the space of 4-5/16 inches is required over the cabinet, the mechanism fits situations where there is enough headroom above the case, such as wall cabinets beneath taller ceilings or open shelving. The slim design and installed location maximizes space inside of the cabinet, which makes the mechanism suitable when maintaining interior volume is important for storage capacity behind the flap.
The lift-assist mechanism is described as providing extra light-opening, which supports repeated daily operation by reducing the effort required each time the flap is raised. The statement that the door stays in any desired position means the lift mechanism holds the flap at various angles, which is useful during tasks that require the door to remain partially open while accessing contents. Damper equipped construction delivers soft and silent closing at the end of travel, which controls the final movement of the flap as it returns to the cabinet and helps manage impact on the case front. Door height adjustability of horizontal plus or minus 3/64 inch and vertical plus or minus 5/64 inch provides small but important adjustments, so the installer can refine reveals and alignment between this flap and neighboring cabinet components. The product is noted as having successfully passed 30,000 open and close private cycle tests, which reflects testing of the mechanism through many operating cycles and speaks to its role in long-term flap door function over repeated use.
The lift-assist mechanism is described so the door opens over the cabinet, meaning the flap travels upward and in front of the cabinet top to clear the opening.
The mechanism requires a space of 4-5/16 inches over the cabinet, which defines the minimum overhead clearance needed when positioning the cabinet and flap door.
The product description states that the door stays in any desired position, so the mechanism holds the flap at partial or full open angles during access.
The mechanism is damper equipped for soft and silent closing at the end, so it slows the flap during final travel and reduces closing impact.
Door height is adjustable horizontally plus or minus 3/64 inch and vertically plus or minus 5/64 inch, enabling small corrections to reveals and alignment relative to the cabinet.
The lift-assist mechanism has successfully passed 30,000 open and close private cycle tests, indicating performance verified through repeated operating cycles.
This Sugatsune America lift-assist mechanism is identified as manufacturer part EZS-ELAN-ML and Lift Assist Mechanism 485 - 550 PSI, which defines the specific unit used for flap doors opening over a cabinet. The stated space of 4-5/16 inches required over the cabinet, combined with the door staying in any desired position, supports projects where overhead clearance is known and hands-free access is important. The slim design that maximizes space inside of the cabinet, along with soft and silent closing from the integrated damper, gives a compact solution for controlled flap motion in storage or work-area cabinetry.
