The DEGOL LH1125 Modern Streamlined Curved Tapered Door Lever Handle on Round Rose is a contemporary architectural door hardware design featuring a flowing curved profile, a gradually tapered gripping section and a compact circular mounting rose.
Inspired by modern minimalist interior design, the LH1125 combines soft organic curves with a clean metallic appearance. The lever begins with a broader, smoothly shaped connecting section near the round rose and gradually narrows toward a slender, rounded tip, creating an elegant streamlined silhouette.
Unlike conventional straight tubular lever handles, the LH1125 features a distinctive swept-curved profile that emphasizes visual continuity and architectural simplicity.
The reference product is illustrated with a satin brushed metallic appearance, with satin nickel and satin chrome identified as example finish options. The combination of its flowing geometry and understated finish makes the LH1125 suitable for consideration in modern residential, hospitality, office and commercial interior environments.
With zinc alloy and aluminum alloy material options, the LH1125 offers flexibility for architectural hardware distributors, international importers, interior door manufacturers and wholesale project buyers.
The engineering reference drawing identifies a 125 mm lever length, 58 mm installed projection, Ø50 mm circular rose and 10 mm rose thickness. It also includes a 29 mm transition segment, 16 mm grip/neck height reference and a proposed Ø18 mm grip thickness.
Designed for compatible interior door applications, the LH1125 features a concealed fixing arrangement and left/right reversible configuration according to the supplied reference specification.

The DEGOL LH1125 is a modern lever-operated architectural door handle featuring a streamlined curved gripping profile mounted on a circular decorative rose.
The handle is characterized by a sweeping, gradually narrowing lever body that creates an organic visual transition from the central mounting area toward the outer gripping end.
Unlike traditional straight cylindrical door handles, the LH1125 incorporates a flowing tapered shape that gives the product a lighter and more dynamic architectural appearance.
Its rounded edges, satin metallic surface and compact circular rose make it suitable for contemporary interior hardware collections.
1. Streamlined Curved Lever
The primary lever features a sweeping curved shape designed to create a smooth, continuous silhouette.
The wider section near the mounting area gradually transitions into a narrower outer grip.
2. Tapered Gripping Section
The lever body narrows progressively toward the outer end.
The proposed grip thickness is approximately Ø18 mm, subject to physical sample verification.
Because the lever is tapered rather than uniformly cylindrical, the actual cross-section may vary along its length.
3. Curved Transition Segment
The transition between the central mounting area and the main gripping profile is indicated as 29 mm in the reference drawing.
This section helps define the distinctive flowing geometry of the LH1125.
4. Rounded Lever Tip
The outer end features a softly rounded, slender profile.
This gives the handle a refined appearance without a sharply squared termination.
5. Round Decorative Rose
The LH1125 features a circular mounting rose with an outside diameter of Ø50 mm and a reference thickness of 10 mm.
6. Inner Mounting Base
The engineering drawing indicates an inner base or sub-rose diameter of Ø38 mm.
This reference dimension relates to the central mounting arrangement.
7. Concealed Fixing Structure
The reference specification identifies concealed fixing to minimize visible mounting hardware after installation.
8. Square Spindle Interface
A proposed 8 × 8 mm square spindle interface is illustrated for connection to a compatible lever-operated lock mechanism.
The final spindle dimensions, length and mounting arrangement require verification.
