1. Product Introduction

The DEGOL LH1130 Modern Straight Tubular Door Lever Handle with Stepped Neck on Round Rose is a contemporary architectural door hardware design featuring a straight cylindrical lever, a distinctive stepped connecting neck, a smooth rounded lever end and a circular decorative rose.

Designed for modern residential and commercial interiors, the LH1130 combines clean geometric lines with a refined metallic appearance. Its straight tubular gripping section creates a simple, balanced silhouette that complements minimalist interior door designs.

Unlike curved or decorative-ring lever handles, the LH1130 emphasizes a uniform cylindrical grip profile and a distinctive stepped neck connection between the lever and the round rose.

The connecting neck features an angular geometric transition that provides a recognizable architectural detail while maintaining the clean overall appearance of the handle.

The main cylindrical gripping section has a reference diameter of Ø19 mm, with a smooth rounded outer end identified by an R9 radius reference.

The reference illustration shows a satin metallic appearance, with satin nickel and brushed nickel identified as surface finish options.

Zinc alloy and aluminum alloy are listed as material options, allowing buyers to evaluate different product configurations according to their market and project requirements.

According to the supplied engineering reference drawing, the LH1130 features a 128 mm overall lever length, 64 mm projection from the door face, Ø52 mm round rose and 10 mm rose thickness.

The stepped connecting neck has a reference length of 18 mm and height of 16 mm.

Additional reference specifications include a Ø38 mm mounting base, two Ø5 mm fixing holes, a reference fixing-hole pitch of 38 mm, an 8 × 8 mm square spindle and a suitable door thickness range of 35–45 mm.

The LH1130 is intended for compatible interior door applications and features a concealed fixing arrangement.

Its modern tubular design makes it a product option for architectural hardware wholesalers, building hardware distributors, interior door manufacturers, construction project buyers and private-label door hardware brands.

DEGOL Hardware welcomes wholesale and OEM / ODM inquiries for the LH1130 straight cylindrical lever handle, including material selection, surface finishes, technical drawings, sample information and customized packaging requirements.

2. Product Definition

The DEGOL LH1130 is a modern lever-operated architectural door handle featuring a straight cylindrical gripping section mounted on a circular decorative rose.

The product is characterized by its uniform tubular lever profile, angular stepped connecting neck and rounded outer end.

Its geometric design combines a simple cylindrical gripping section with a more structured neck connection.

This combination creates a contemporary appearance suitable for modern interior door hardware collections.

The LH1130 can be considered for residential, hospitality, office and other compatible interior door applications.

Main Structural Components

1. Straight Cylindrical Lever

The main lever features a straight tubular profile.

The reference lever diameter is Ø19 mm.

The cylindrical shape provides a clean visual appearance and distinguishes the LH1130 from flattened, curved or heavily decorative lever handle designs.

2. Stepped Connecting Neck

The LH1130 features a distinctive stepped connecting neck between the cylindrical lever and the mounting assembly.

The engineering drawing identifies a neck length of 18 mm and a neck height of 16 mm.

The stepped geometry creates an angular transition from the round mounting assembly to the cylindrical lever.

This structural detail is one of the main visual characteristics of the LH1130 design.

3. Rounded Lever End

The outer end of the cylindrical lever features a smooth rounded termination.

The engineering drawing identifies an R9 radius reference.

This rounded end complements the straight tubular lever profile and provides a refined finishing detail.

4. Round Decorative Rose

The LH1130 features a circular decorative rose with a reference outside diameter of Ø52 mm.

The rose thickness is identified as 10 mm.

The round rose creates a balanced appearance around the central lever mounting assembly.

5. Central Mounting Assembly

The central mounting assembly connects the lever to the door through the round rose and mounting base.

The product illustration shows a metallic central collar and stepped neck transition.

Final component construction and assembly details should be confirmed against the approved physical sample.

6. Circular Mounting Base

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

The mounting base includes two Ø5 mm fixing holes and a central square spindle opening.

7. Square Spindle Interface

The handle uses a reference 8 × 8 mm square spindle interface.

The spindle is intended to connect the lever handle to a compatible latch or mortise lock mechanism.

The final spindle length and lock compatibility must be confirmed before installation.
