Aluminum Lift-Off Hinge 2-1/4 Width Left Hand describes a specialty hinge designed specifically for aluminum profiles, so it supports projects built around aluminum framing rather than traditional wood cases. This product is a lift-off hinge, meaning the door or panel can be lifted free of the hinge without driving out pins, which speeds removal during assembly, machining, or service work. The hinge is part of the AS-HG-AL-N Series from Sugatsune America, so it follows a consistent design family that helps keep hardware choices standardized across similar aluminum-profile builds. Its 2-1/4 inch width sets the hinge footprint on the frame or stile, which helps installers plan profile size and hinge spacing on taller or heavier doors. Plastic bushings provide smooth movement at the pivot, so doors swing with reduced friction, which matters when panels are opened and closed repeatedly along an aluminum frame line.
This aluminum lift-off hinge belongs to the AS-HG-AL-N Series, so its geometry and performance are tailored to aluminum profiles, which guides where it lands on the extrusion during layout. Its 2-1/4 inch width provides a known mounting footprint on the profile face, allowing installers to size the door edge and profile leg around the hinge leaf. The Left Hand orientation defines which side of the opening the hinge serves, shaping how the door or panel swings relative to fixed aluminum framing. Because it is a lift-off hinge, the mounted door can be removed by lifting, helping during on-site adjustments or later component access without altering the hinge position.
This aluminum lift-off hinge is described as designed for aluminum profiles, so it is intended to mount directly to aluminum framing members rather than wood rails. In practical terms, that design focus supports use on aluminum-framed doors, panels, or access covers where the hinge leaf aligns with the flat surfaces of the profile. The 2-1/4 inch width defines how far the hinge extends across the face of the aluminum, which helps plan clearances between neighboring profiles or hardware runs. The Left Hand configuration clarifies which edge of the door the hinge supports, which matters when multiple doors or panels share a frame and must swing in coordinated directions along an aluminum structure. As a lift-off hinge, it allows the panel to be lifted away from the fixed leaf, so doors can be removed from aluminum assemblies during fabrication or service while leaving the hinge locations stable on the profiles.
The presence of plastic bushings in this hinge provides smooth movement at the pivot point, so the motion of the door remains controlled as it swings on aluminum framing. That bushing design helps the hinge move with less friction at the joint, which is valuable when panels are cycled repeatedly in work areas or service spaces. Being part of the AS-HG-AL-N Series from Sugatsune America groups this hinge within a defined product line, so installers can rely on consistent behavior and dimensions when the same series is used across multiple openings. The AS-HG-AL-NL3040 designation pinpoints this Left Hand, 2-1/4 inch width version, which supports accurate replacement or duplication of existing hardware setups. Because this hinge is categorized under Specialty Hinges and specifically as a Lift-Off Hinge, it signals that its primary role is to allow panel removal while keeping hinge locations fixed, which can reduce rework when doors need to be taken off and reinstalled around aluminum-profile structures.
This aluminum lift-off hinge is designed for aluminum profiles, so it fits projects that build doors or panels onto aluminum framing systems or aluminum structural profiles.
The 2-1/4 inch width defines the hinge footprint on the profile or door edge, which helps determine spacing, edge distances, and how many hinges are used along a stile.
The plastic bushings provide smooth movement at the pivot, so doors or panels on aluminum profiles swing more easily and operate with more consistent motion over time.
The Left Hand configuration sets the handing of the hinge, so it matches the intended swing direction of the door or panel on the aluminum profile frame.
The AS-HG-AL-NL3040 part number identifies this specific Sugatsune America aluminum lift-off hinge, supporting consistent reordering for the same application.
The lift-off hinge design lets the door be removed by lifting it off the hinge, so access to components behind aluminum-framed panels is faster without disturbing hinge placement.
This Aluminum lift-off hinge for aluminum profiles combines a 2-1/4 inch width, Left Hand configuration, and plastic bushings to support panels built on aluminum framing. The AS-HG-AL-NL3040 designation from Sugatsune America defines a repeatable choice for projects that need smooth panel motion and removable doors along aluminum-profile structures. For aluminum-based builds that call for a specialty lift-off hinge, this model aligns the hinge style with the profile-focused design.
