The DEGOL LH1112 Modern Slim Tapered Curved Door Lever Handle Set is a contemporary architectural door hardware design featuring a gently swept lever profile, a smooth tapered gripping section, and a compact circular mounting rose.
Designed with clean lines and a minimalist appearance, the LH1112 offers a refined alternative to traditional straight tubular door handles and bulky decorative lever designs.
The lever extends outward from a rounded connecting neck and gradually narrows toward a softly rounded outer tip. Its subtle curvature creates a flowing silhouette, while the compact round rose provides a balanced and understated mounting appearance.
The supplied engineering reference drawing indicates a lever length of approximately 110 mm, a handle projection of approximately 60 mm, and a maximum grip width of approximately 23 mm.
The illustrated mounting rose measures approximately 48 mm in diameter and 8 mm in thickness. A reference hub diameter of approximately 24 mm is also provided.
These proportions distinguish the LH1112 from longer curved blade handles and larger decorative lever designs.
The drawing shows a satin brushed metallic appearance and identifies stainless steel as a possible material category, with SUS304 and SUS201 listed as examples. However, the actual LH1112 material grade, manufacturing construction, and surface treatment have not been independently verified.
The exploded assembly illustration shows two opposing lever handles, round mounting components, a square spindle, and two round keyhole escutcheons.
The exact commercial package contents, including whether the escutcheons are supplied as standard, must be confirmed before ordering.
The LH1112 design can be considered for modern residential interiors, apartments, offices, hospitality projects, and compatible commercial interior applications.
Its slim tapered profile and compact round rose make it particularly relevant to architectural hardware collections that emphasize clean detailing and contemporary door fittings.
Jiangmen Degol Hardware Co., Ltd. welcomes wholesale, OEM, and ODM inquiries from international architectural hardware importers, door handle distributors, door manufacturers, building material suppliers, contractors, and project purchasing teams.
Important: The supplied drawing is an engineering reference based on user-provided dimensions and a DEGOL product image.

The DEGOL LH1112 is a modern lever-on-round-rose door handle design characterized by its gently curved profile, slim tapered gripping section, compact circular mounting rose, and understated architectural appearance.
A lever door handle is an architectural hardware component used to operate a compatible latch or locking mechanism through a spindle connection.
The LH1112 differs from conventional straight tubular handles because its gripping section gradually changes shape along its length.
Rather than maintaining a constant cylindrical diameter, the illustrated lever features a fuller inner section that tapers smoothly toward a narrower outer tip.
Its overall profile is gently swept rather than sharply angular, creating a clean and flowing appearance.
1. Slim Tapered Lever Profile
The defining feature of the LH1112 is its slim tapered gripping section.
The handle begins with a fuller profile near the connecting neck and becomes narrower toward its outer end.
This gradual taper creates a refined contemporary silhouette.
2. Gently Curved Design
The lever features a subtle swept curvature.
Its flowing shape provides a softer visual effect than straight rectangular or cylindrical lever handles.
3. Rounded Outer Tip
The outer end narrows to a smooth, rounded tip.
The actual tip thickness, edge radius, and final geometry must be verified through approved technical documentation.
4. Sculpted Gripping Section
The illustrated lever has smooth blended surfaces with a reference maximum width of approximately 23 mm.
The changing profile creates a sculpted appearance rather than a uniform tubular shape.
5. Rounded Connecting Neck
The lever connects to the mounting rose through a rounded neck and hub assembly.
The reference hub diameter is approximately 24 mm.
6. Compact Round Mounting Rose
The lever is illustrated on a circular rose measuring approximately 48 mm in diameter.
The compact rose complements the slim lever profile.
7. Low-Profile Rose Appearance
The reference rose thickness is approximately 8 mm.
The actual internal mounting plate and decorative cover construction must be confirmed.
8. Square Spindle Connection
The reference drawing identifies an 8 × 8 mm square spindle.
The final spindle size, length, and compatibility must be verified before installation.
9. Matching Keyhole Escutcheon Illustration
The exploded assembly view shows two round keyhole escutcheons.
Their exact profile, dimensions, fixing method, and inclusion in the commercial package are not confirmed.
The preliminary drawing illustrates:
Two opposing slim tapered curved lever handles
Round decorative mounting roses
Internal fixing plates
Square spindle
Two round keyhole escutcheons
The final supplied quantity of each component, fixing screws, installation accessories, and packaging arrangement must be confirmed through the approved quotation or packing list.
A mortise lock case or lock cylinder should not be assumed to be included.

Specification Notice: The supplied engineering drawing contains reference dimensions based on a user-provided sketch and a DEGOL product image. These values have not been verified against an approved LH1112 manufacturing drawing. Material grades, surface treatments, spindle dimensions, installation compatibility, and package contents require confirmation before ordering.
The preliminary LH1112 engineering reference drawing illustrates the lever handle set through several technical views:
Side view of the lever profile
Front elevation
Top plan view
Round mounting rose detail
Rose thickness detail
Hub diameter detail
Exploded assembly view
Typical installation section
Main dimension table
Reference specification table
These views provide a preliminary understanding of the slim tapered lever geometry, compact round mounting rose, and paired door installation arrangement.
The drawing indicates a lever length of 110 mm, measured from the neck datum to the outer tip.
This dimension is important for evaluating the compact proportions of the LH1112.
The illustrated lever is shorter than several comparable longer curved lever designs.
However, the measurement is a reference value and must be verified against the actual product.
The drawing indicates a handle projection of 60 mm.
Projection is relevant when evaluating the installed depth of the handle and available clearance from the door surface.
The final installed projection must be confirmed using the approved mounting configuration.
The reference maximum grip width is 23 mm.
Because the LH1112 features a tapered gripping profile, its width changes along the lever.
This value should not be interpreted as a uniform cylindrical diameter.
The front and top views illustrate a gently swept lever that narrows toward its outer tip.
The design combines a fuller connecting section with a slim, elongated outer profile.
The actual curvature, cross-sectional geometry, and edge radii must be verified before manufacturing.
The illustrated mounting rose has a reference diameter of 48 mm.
Its compact circular design creates a balanced appearance with the slim tapered lever.
The actual production diameter must be confirmed.
The drawing indicates a rose thickness of 8 mm.
The final installed thickness may depend on the decorative cover, internal fixing plate, and mounting construction.
The technical drawing identifies a hub diameter of 24 mm.
The hub is the connecting section between the lever and the mounting rose.
This dimension may be relevant when evaluating the handle's appearance, assembly structure, and compatibility with the mounting mechanism.
The actual hub diameter and construction must be verified.
The reference specification identifies an 8 × 8 mm square spindle.
The spindle transfers rotational movement from the lever to a compatible latch or lock mechanism.
The final spindle dimensions, length, and engagement requirements must be confirmed before installation.
The installation section illustrates a door thickness range of 35–55 mm.
This is a typical reference range rather than a verified LH1112 compatibility specification.
Actual suitability depends on the final spindle, fixing arrangement, selected lock, and door construction.
The exploded assembly view shows decorative round roses and internal fixing plates.
The illustration provides a general indication of the mounting arrangement.
However, the actual mounting-hole spacing, screw sizes, fixing method, and assembly tolerances are not confirmed.
The exploded drawing includes two round keyhole escutcheons.
Their appearance suggests a cylinder-style keyhole configuration.
However, the exact keyhole profile, opening dimensions, escutcheon diameter, and locking compatibility are not specified.
The escutcheons should not be described as confirmed standard accessories until the final packing list has been verified.
The installation section illustrates opposing lever handles mounted on both sides of a door.
The drawing shows the square spindle passing through the door and connecting the two lever assemblies.
This is a general installation reference and does not establish universal reversibility or compatibility with every mortise lock.
The notes specify a general reference tolerance of ±0.5 mm.
This value is not an approved manufacturing tolerance for LH1112.
Final tolerances must be established in approved production drawings.

The reference information must not be interpreted as confirmation that the product is manufactured from SUS304, SUS201, or another specific stainless steel grade.
Customers requiring a particular material should request written confirmation from DEGOL before ordering.
The reference specification identifies a satin brushed metallic appearance.
This finish style complements the slim tapered lever profile and creates a contemporary architectural look.
Its neutral metallic tone can coordinate with wooden doors, painted interior doors, metal frames, and other silver-toned architectural fittings.
The actual surface finish and production process must be confirmed.
Polished metallic finishes may be considered for architectural projects requiring a brighter reflective appearance.
Availability for LH1112 must be confirmed according to the selected material and manufacturing process.
The reference specification lists PVD black as an example of a possible finish category.
This should be treated as a customization inquiry rather than a confirmed standard LH1112 finish.
Customers should request confirmation of availability, coating specifications, and performance requirements.
PVD gold is another finish category mentioned in the reference specification.
Actual PVD gold availability, color, coating process, and performance characteristics must be confirmed with DEGOL.
The drawing alone does not establish that LH1112 is supplied with a PVD coating.
The LH1112 design features a sculpted gripping section with gradually changing width.
The smooth visual transition from the connecting neck to the tapered outer tip is an important design characteristic.
Actual surface quality, edge smoothness, and dimensional consistency should be evaluated using approved product samples.
Customers may request evaluation of:
Satin Silver
Brushed Stainless Steel Appearance
Polished Silver
Matte Black
