The DEGOL LH1123 is a modern lever-operated interior door handle featuring a round rose, a smoothly curved connecting neck and a straight cylindrical gripping section.
The defining visual characteristic is the transition between the central mounting assembly and the horizontal grip.
Unlike basic straight-neck lever handles, the LH1123 features a sweeping curved neck that gives the product a softer and more architectural appearance.
The contrasting satin brushed and polished chrome surfaces further distinguish the product from conventional single-finish tubular lever handles.
1. Straight Cylindrical Grip
The primary gripping section features a straight tubular profile with a proposed diameter of Ø20 mm.
Its rounded geometry creates a smooth gripping surface and a minimalist architectural appearance.
2. Curved Connecting Neck
The curved neck forms a flowing connection between the round rose and horizontal cylindrical grip.
This geometric transition is a distinctive feature of the LH1123 design.
3. Polished Connecting Section
The neck and adjacent inner collar feature a polished chrome appearance in the reference image, creating visual contrast with the satin brushed surfaces.
4. Round Decorative Rose
The mounting rose has a reference outer diameter of Ø51 mm and a reference thickness of 10 mm.
Its circular shape complements the rounded lever grip.
5. Central Mounting Assembly
The central mounting area connects the lever to the door surface.
The exact fixing arrangement and mounting accessories require confirmation.
6. Square Spindle Interface
The reference drawing proposes an 8 × 8 mm square spindle for use with a compatible lever-operated latch or mortise lock.

The separate spindle cross-section illustrates a proposed 8 × 8 mm square interface.
Final spindle length, mounting positions, fastening components and compatibility with the selected lock mechanism must be confirmed.
Before preparing manufacturing tooling or approving a production order, the following items should be verified:
Overall lever reach and installed projection.
Curved neck geometry and transition radii.
Rose outside diameter and thickness.
Cylindrical grip diameter.
Square spindle dimensions and engagement.
Mounting-hole arrangement and fixing components.
Material selection and surface finish requirements.

Reference Drawing Disclaimer: The drawing is marked "Not for Tooling." Market reference measurements and proposed dimensions are not substitutes for an approved production drawing or verified physical sample.
The DEGOL LH1123 reference specification identifies zinc alloy and aluminum alloy as available material options for evaluation.
Zinc alloy is widely used in decorative architectural hardware because it supports shaped metal components and various finishing processes.
Potential characteristics include:
Suitable for curved decorative hardware components.
Good potential for detailed casting geometry.
Compatible with appropriate plating and coating processes.
Suitable for contemporary interior door hardware styling.
Flexible decorative surface treatment options.
The exact zinc alloy grade, component construction and finishing process should be confirmed before ordering.
Aluminum alloy provides an alternative material choice for architectural door hardware.
Potential characteristics include:
Lower material density than zinc alloy.
Suitable for selected modern hardware configurations.
Compatibility with appropriate aluminum finishing processes.
Contemporary metallic appearance.
Potential for customized product development.
Material selection should consider mechanical requirements, manufacturing methods, available finishes and project specifications.
The illustrated LH1123 combines two visually distinct metallic surface treatments.
Satin Brushed Lever and Rose
The main cylindrical grip and outer round rose feature a satin brushed appearance.
This finish creates a soft metallic reflection and emphasizes the clean geometric surfaces.
Polished Chrome Neck and Inner Collar
The curved connecting neck and central decorative collar incorporate polished chrome accents.
These reflective areas provide visual contrast against the satin brushed components.
The resulting two-tone combination creates a refined contemporary appearance.
