1. Product Introduction

The DEGOL LH1124 Modern Curved Tapered Door Lever Handle on Round Rose is a contemporary architectural door hardware design combining a graceful curved lever profile, a smooth tapered grip and a compact circular mounting rose.

Created for modern interior door applications, the LH1124 features a flowing lever shape that gradually transitions from a narrower connecting section into a wider, rounded gripping end. This distinctive geometry gives the handle a refined appearance while maintaining the simplicity associated with minimalist architectural hardware.

The illustrated product features a satin metallic appearance, with satin nickel and satin chrome identified as reference finish options. The smooth lever surface and circular rose create a balanced design suitable for contemporary residential, hospitality, office and commercial interior environments.

With zinc alloy and aluminum alloy material options, the LH1124 provides a versatile design reference for architectural hardware distributors, interior door manufacturers, construction projects and international wholesale buyers.

The engineering reference drawing indicates a 125 mm lever length, 62 mm installed projection, Ø50 mm round rose and 8.5 mm rose thickness. A proposed Ø20 mm grip dimension and 8 × 8 mm square spindle interface are also shown.

The LH1124 is designed for compatible interior door applications, with concealed fixing and a left/right reversible configuration identified in the reference specification.

DEGOL Hardware welcomes wholesale inquiries from international distributors, hardware importers, architectural projects and private-label brands seeking contemporary curved lever handle designs.

2. Product Definition

The DEGOL LH1124 is a lever-operated architectural door handle featuring a curved, tapered metal grip mounted on a circular decorative rose.

Unlike straight cylindrical door handles or sharply angular lever designs, the LH1124 has a smooth flowing profile that gradually changes in width along the gripping section.

The lever begins with a relatively narrow neck near the mounting rose and extends outward toward a broader, rounded end.

This distinctive shape combines a soft contemporary appearance with a practical lever-operated configuration.

Main Structural Components

1. Curved Tapered Lever

The main lever features a gently curved outline and a gradual tapered profile.

Its smooth surface and rounded extremity create an understated contemporary appearance.

2. Narrow Connecting Neck

The narrower section near the rose provides a visual transition between the central mounting area and the main lever grip.

The reference drawing indicates a neck transition dimension of approximately 36–37 mm along the illustrated lever profile.

3. Rounded Lever End

The outer end features a smooth, softly rounded geometry rather than a sharp rectangular termination.

The drawing proposes an approximate Ø20 mm dimension at the grip end, subject to verification.

4. Round Decorative Rose

The LH1124 uses a circular mounting rose with a reference outside diameter of Ø50 mm.

The rose maintains a compact and balanced visual relationship with the curved lever.

5. Inner Mounting Base

The drawing identifies an inner base or sub-rose diameter of Ø38 mm.

This component forms part of the central mounting arrangement.

6. Concealed Fixing Structure

The reference specification identifies concealed fixing, intended to keep mounting hardware out of view after installation.

The actual fastening system must be confirmed from the approved product assembly.

7. Square Spindle Interface

The reference drawing identifies a proposed 8 × 8 mm square spindle interface, commonly used with compatible lever-operated lock mechanisms.

Final spindle length and lock compatibility require confirmation.

Important Engineering Notice: Reference dimensions only. Verify all measurements against an approved physical sample before tooling or manufacturing.


5. Material & Surface Finish

The DEGOL LH1124 reference specification provides zinc alloy and aluminum alloy as material options.

The final material selection should be confirmed according to the intended application, manufacturing configuration and project requirements.

5.1 Zinc Alloy Material

Zinc alloy is commonly used in decorative architectural door hardware because of its suitability for shaped metal components and various finishing methods.

Potential benefits include:

  • Suitable for curved and tapered component geometry.

  • Good potential for decorative casting detail.

  • Compatibility with appropriate plating and coating processes.

  • Smooth surface preparation for decorative finishes.

  • Versatility for contemporary interior door hardware collections.

The selected zinc alloy grade and manufacturing process should be specified before production.

5.2 Aluminum Alloy Material

Aluminum alloy provides an alternative material option for modern lever handle designs.

Potential benefits include:

  • Relatively lightweight material characteristics.

  • Modern metallic appearance.

  • Compatibility with suitable aluminum finishing processes.

  • Potential for material-specific product customization.

  • Suitable for selected interior architectural hardware applications.

The exact aluminum alloy grade, construction method and coating requirements must be confirmed for the ordered configuration.

5.3 Satin Nickel Finish

Satin nickel offers a soft metallic appearance with subdued reflections.

This surface style can complement modern wooden doors, neutral interior color schemes and minimalist architectural fittings.

Its understated appearance makes it suitable for consideration in residential, hospitality and office interior designs.

5.4 Satin Chrome Finish

Satin chrome provides a clean metallic appearance with a less reflective surface than polished chrome.

It can coordinate with contemporary door hardware, furniture fittings and other metallic interior elements.

5.5 Optional Surface Finish Inquiries
