Lift Assist Mechanism 380 - 485 PSI is a Sugatsune America lift-assist mechanism designed to support flap doors so they open over the cabinet while easing the lifting effort. The mechanism is part of the Lid Supports and Stays product class, so it is built specifically to control door motion rather than just hold static weight. The door opens over the cabinet when proper clearance is available, which allows the front to move up and out of the way instead of swinging into the workspace. A required space of 4-5/16 inches over the cabinet is specified, which sets a clear reference when planning casework height and overhead clearance. The unit functions as a lift-assist for extra light-opening, which helps reduce the effort needed to raise the door into position during regular use.
The mechanism is described as having simple installation by aligning the body to the edge of the cabinet, which gives a straightforward mounting reference along the case side. This alignment-based approach helps speed layout because the body position is based on the cabinet edge rather than complex templates. Door height is adjustable horizontally plus or minus 3/64 inch and vertically plus or minus 5/64 inch, providing small but meaningful correction in both directions to fine-tune the reveal. These adjustment ranges matter when matching adjacent fronts or correcting slight drilling variations so the flap sits visually even with neighboring fronts after installation.
The SAP description defines this product as EZS FLAP DOOR LIFT MECHANISM 185-280 PSI with manufacturer part number EZS-ELAN-LL, tying it directly to the EZS flap door system for lift-up fronts. The mechanism is categorized under Work Surface & Tables and Lift Systems, Lid Supports and Stays, indicating its role wherever flap-style cabinet doors are specified instead of traditional swing doors. The door opens over the cabinet when 4-5/16 inches of space is provided above, so it suits installations with that overhead clearance available, such as upper cabinets or enclosures with room above the case. Because the lift-assist function provides extra light-opening, it is especially useful where users repeatedly lift the same front throughout the day and want the mechanism to support part of that motion. The ability for the door to stay in any desired position also means it works well in workstations where the flap may be left partly open while accessing contents, since the mechanism holds that angle without drifting.
The damper equipped design provides soft and silent closing at the end of the stroke, so the door decelerates as it comes down and settles against the cabinet more quietly. This controlled closing reduces abrupt contact at the final moment, which can lessen noise in shared spaces and moderate the final load on the mounting points. The slim design and installed location maximize space inside the cabinet, keeping more interior area clear for storage because the hardware runs compactly along the side. With no hinges or connecting bar needed, the mechanism simplifies the motion system and removes components that would otherwise share the movement, which can streamline layout when configuring flap doors. The door height adjustment of horizontal plus or minus 3/64 inch and vertical plus or minus 5/64 inch enables precise tuning of the front position after mounting. These fine adjustments allow the installer to align the flap with adjacent doors or panels, improving the finished appearance and helping doors close consistently against the case. The fact that the product successfully passed 30,000 open/close private cycle tests shows that the motion components are designed for repeated operation over many cycles, supporting long-term performance in cabinets that see frequent opening and closing.
The Lift Assist Mechanism 380 - 485 PSI is defined as an EZS flap door lift mechanism, so it is intended for flap-style doors that lift up rather than swing out.
The product specifies that the door opens over the cabinet and requires 4-5/16 inches of space above, which sets the clearance needed when planning the installation height.
The mechanism allows the door to stay in any desired position, so the flap can remain partially or fully open at whatever angle is most useful during cabinet access.
The mechanism is damper equipped for soft and silent closing at the end, slowing the last part of travel so the door settles against the cabinet more gently and quietly.
Door height is adjustable horizontally plus or minus 3/64 inch and vertically plus or minus 5/64 inch, allowing fine tuning of the door position for an even reveal.
Installation is described as simple by aligning the body to the edge of the cabinet, providing a clear reference line for locating the mechanism on the case side.
The EZS-ELAN-LL lift-assist mechanism from Sugatsune America provides extra light-opening support, door position holding, and soft closing for flap doors that open over the cabinet. With a specified 4-5/16 inches of required space above the cabinet and defined horizontal and vertical door height adjustments, it helps translate design dimensions into a controlled, repeatable door motion. The slim design and side-mounted location preserve interior space, while the absence of separate hinges or a connecting bar simplifies the motion layout. For projects calling for a tested flap door lift system within the Work Surface & Tables and Lift Systems, Lid Supports and Stays category, this mechanism offers a clearly defined motion profile and installation reference.
