1. Product Introduction

The DEGOL LH1129 Modern Swept Curved Flat-Grip Door Lever Handle on Round Rose is a contemporary architectural door hardware design featuring an elegant swept curved lever, a gradually tapered flat gripping section, a cylindrical connecting neck and a circular decorative rose.

Designed for modern residential and commercial interiors, the LH1129 combines smooth flowing lines with a refined metallic appearance. Its gently downward-curving lever profile creates a distinctive architectural silhouette, offering an alternative to conventional straight tubular and rectangular door handles.

Unlike traditional cylindrical lever handles with a uniform round gripping section, the LH1129 features a specially shaped flattened grip that gradually changes in cross-section along the lever.

The main gripping section measures approximately 22 × 10 mm, while the section near the outer tip transitions to approximately 18 × 9 mm.

This gradual dimensional transition creates a streamlined visual appearance and a distinctive grip profile.

The lever incorporates an approximately 8 mm curve offset, producing a subtle downward sweep that distinguishes the LH1129 from straight cylindrical lever designs.

The handle connects to the central mounting assembly through a Ø16 mm cylindrical neck, which transitions into the curved main lever.

The circular decorative rose features a reference outside diameter of Ø52 mm and a thickness of 10 mm.

According to the supplied engineering reference drawing, the LH1129 has an overall lever length of 128 mm and a projection from the door face of 60 mm.

The product illustration features a satin metallic appearance, with satin nickel and brushed nickel identified as reference surface finishes.

Zinc alloy and aluminum alloy are listed as material options.

The mounting arrangement includes a circular Ø38 mm mounting base, two Ø5 mm fixing holes and an 8 × 8 mm square spindle interface.

The reference suitable door thickness is 35–45 mm.

The LH1129 is intended for compatible interior door applications and features a concealed fixing arrangement.

DEGOL Hardware welcomes wholesale and OEM / ODM inquiries from architectural hardware importers, building hardware distributors, door manufacturers, construction project suppliers and private-label hardware brands.

2. Product Definition

The DEGOL LH1129 is a lever-operated architectural door handle featuring a gently curved flat-profile gripping section mounted on a circular decorative rose.

The product is characterized by its smooth swept lever geometry, cylindrical connecting neck and gradually changing grip cross-section.

Its flowing shape creates a modern architectural appearance that differentiates it from conventional straight cylindrical and angular lever handles.

The LH1129 can be considered for contemporary interior door hardware collections where a curved lever design is preferred.

Main Structural Components

1. Swept Curved Lever

The main lever features a gentle downward-curving profile.

The engineering drawing indicates a reference curve offset of 8 mm.

This curved geometry creates a smooth, flowing visual appearance.

2. Flattened Main Gripping Section

The main gripping section features a flattened profile rather than a conventional circular cross-section.

The reference dimensions are 22 × 10 mm.

This shape contributes to the distinctive appearance of the LH1129.

3. Tapered Outer Grip Section

The lever gradually transitions toward a smaller cross-section near the outer tip.

The reference dimensions near the tip are 18 × 9 mm.

This gradual reduction helps create the streamlined profile.

4. Cylindrical Connecting Neck

The lever connects to the mounting assembly through a cylindrical neck with a reference diameter of Ø16 mm.

The neck provides a transition between the circular mounting structure and the curved flat gripping section.

5. Curved Lever End

The outer end follows the overall swept profile of the handle.

Its softly finished termination complements the flowing design.

6. Round Decorative Rose

The LH1129 features a circular decorative rose with a reference outside diameter of Ø52 mm.

The reference rose thickness is 10 mm.

7. Circular Mounting Base

The engineering drawing illustrates a circular mounting base with a reference diameter of Ø38 mm.

Two Ø5 mm fixing holes are shown in the mounting base detail.

8. Square Spindle Interface

The product drawing identifies an 8 × 8 mm square spindle interface.

The final spindle length and lock compatibility must be confirmed according to the approved door and lock configuration.

4.1 Side Elevation – Assembled

The side elevation illustrates the complete swept curved lever handle mounted on the circular decorative rose.

The overall lever length is identified as 128 mm.

The projection from the door face is indicated as 60 mm.

The circular rose has a reference outside diameter of Ø52 mm and a thickness of 10 mm.

The connecting neck has a reference diameter of Ø16 mm.

The main lever body gradually transitions into a flattened gripping profile.

The engineering drawing identifies a main grip cross-section of 22 × 10 mm and a smaller section near the tip measuring 18 × 9 mm.

The lever incorporates an approximately 8 mm downward curve offset.

This dimensional arrangement creates the distinctive swept profile of the LH1129.

4.2 Front View – Round Rose

The front view illustrates the relationship between the gently curved lever and circular decorative rose.

The Ø52 mm round rose provides a balanced mounting appearance.

The lever extends horizontally from the central mounting assembly before following a subtle downward curve toward the outer end.

The front view also highlights the transition between the cylindrical neck and the flattened main lever.

4.3 Top View – Lever Profile

The top view illustrates the lever's curved profile and reference projection.

The projection from the door face is identified as 60 mm.

The drawing indicates a maximum grip width of 22 mm.

The lever profile gradually changes along its length, producing a flowing appearance.

The top view also illustrates the smooth transition between the mounting assembly, cylindrical connecting neck and curved gripping section.

4.4 Main Grip Cross-Section

The main gripping section is identified as 22 × 10 mm.

This flattened cross-section distinguishes the LH1129 from traditional round tubular lever handles.

The final edge radii, surface contours and manufacturing tolerances should be confirmed before production.

4.5 Grip Section Near Tip

The section near the outer tip measures approximately 18 × 9 mm.

This smaller cross-section creates a gradual taper toward the end of the handle.

The change in profile contributes to the product's streamlined architectural appearance.

4.6 Lever Curve Offset

The engineering reference drawing indicates a lever curve offset of 8 mm.

This measurement describes the approximate vertical deviation associated with the curved lever profile.

The final curvature, measurement datum and profile tolerances must be confirmed against the approved physical sample.

4.7 Round Rose and Mounting Base Detail

The mounting base detail illustrates a circular mounting structure with a reference diameter of Ø38 mm.

The drawing identifies:

  • Ø38 mm mounting base diameter.

  • Two Ø5 mm fixing holes.

  • 38 mm reference fixing-hole pitch.

  • Central 8 × 8 mm square spindle opening.

The fixing-hole pitch and mounting geometry should be verified before tooling, particularly because the dimensions are presented as engineering references.

4.8 Square Spindle Detail

The drawing identifies an 8 × 8 mm square spindle cross-section.

This spindle interface is intended for use with a compatible lever-operated latch or mortise lock.

The actual spindle length and engagement requirements depend on the selected lock and door configuration.
