Sugatsune Aileron lift-assist lid stay provides a freestop, soft-down stay and lift assist for upward doors rated between 53.1 and 70.8 lb, so heavy fronts can move smoothly without fighting the weight every time the door is used. This lid stay is specially designed for use with the OLYMPIA concealed hinge (360-D26-19), creating an integrated lift system so hinge and stay work together as a matched assembly on the same door. The Aileron System creates continuous door movements with adjustable closing speed and freestop functions, so motion from open to close feels consistent instead of abrupt. Integrated design combines a concealed hinge and lid stay, which keeps the mechanism at the cabinet edge rather than crowding interior space. Board thickness from 9/16 in (15 mm) to 7/8 in (22 mm) is supported, allowing use across many common panel constructions.
This upward-opening stay is described as ARN-3 STAY, UP OPEN, 53.1-70.8 TORQ, which ties the stay directly to a torque range intended for doors weighing 53.1 to 70.8 lb, helping match the mechanism to heavier fronts. It requires minimal 3 ft x 7 ft space for installation, so layout planning can work within that envelope when setting cabinet height and opening clearance. The integrated design with Sugatsune's Olympia hinge means the stay and hinge share a coordinated geometry, simplifying alignment between pivot point and lifting arm on upward doors. Board thickness between 9/16 in and 7/8 in is supported, providing flexibility to use typical cabinet door or panel builds within that range without changing the stay model.
This heavy duty lift-assist stay is rated for 53.1 to 70.8 lb doors, so it is suited to applications where the door or lid carries substantial weight and needs controlled upward movement. The product sits in the Lid Supports and Stays category, indicating its role is to support and control doors rather than act as a primary hinge. It is specially designed for use with the OLYMPIA concealed hinge (360-D26-19), so it is intended for upward doors that already specify this concealed hinge as the main pivot. The Aileron System creates continuous door movements with freestop and soft-down stay behavior, giving upward doors a controlled arc rather than a loose swing. Board thickness from 15 mm to 22 mm supports common casework doors, allowing this stay to be used on many work surface, table, or cabinet fronts in that thickness range.
The lift-assist function allows for light opening of doors, which matters when users repeatedly open heavy upward fronts, because the stay takes on part of the lifting work each time. The free-stop function holds doors at any angle from 30 degrees to maximum, so the door can be set at a convenient height without drifting, which supports stable access while working. The soft-close function makes doors close gently from 30 degrees down to 0 degrees, reducing impact at the frame and hinge line, which can help keep motion consistent for users. Closing speed of doors is adjustable, allowing fine-tuning of the motion curve so heavy doors neither drop quickly nor stay overly slow during closing. Integrated design combines a concealed hinge and lid stay, so the motion of the OLYMPIA concealed hinge and the stay are coordinated, supporting smoother alignment across the entire opening and closing cycle.
The ARN-3-H-S stay is described as 53.1-70.8 TORQ, indicating it is intended for doors in the 53.1 to 70.8 lb range, so heavier upward doors can be assisted through the lift.
The free-stop function enables doors to hold in position from 30 degrees to maximum, so the door can stay at a convenient opening angle during access or work.
The ARN-3-H-S stay supports board thickness from 9/16 in (15 mm) to 7/8 in (22 mm), which fits many cabinet and work surface door constructions in that size range.
The soft-close function makes doors close gently from 30 degrees to 0 degrees, so the final travel is controlled instead of slamming against the cabinet.
The Aileron System is specially designed for use with the OLYMPIA concealed hinge (360-D26-19), so the stay and hinge operate as a matched motion system.
The closing speed of doors is adjustable on this stay, allowing the installer to set how quickly the door settles into the fully closed position.
This Sugatsune Aileron lift-assist lid stay is configured for upward doors between 53.1 and 70.8 lb, pairing lift-assist, freestop, and soft-close in one system so motion remains consistent across daily use. Its integrated design with the OLYMPIA concealed hinge (360-D26-19) delivers a coordinated concealed hinge and stay setup for upward-opening fronts within the 15 mm to 22 mm board thickness range. When a project calls for controlled upward movement, adjustable closing speed, and stable holding positions from 30 degrees to maximum, this ARN-3-H-S lid stay provides those functions in a single matched component set.
