Product Introduction

The DEGOL LH1052 Modern Straight Tubular Door Lever Handle with Curved Neck on Round Rose is a contemporary architectural door hardware design featuring a smooth curved connecting neck, a straight cylindrical gripping section, and a concealed-fixing round rose.

Designed for modern interior doors, the LH1052 combines a minimalist straight lever profile with a flowing curved elbow between the handle and the mounting rose.

Unlike conventional straight lever handles with an angular or sharply defined connecting neck, the LH1052 features a smooth, rounded transition that creates a softer and more refined architectural appearance.

The main gripping section has a straight cylindrical profile with a nominal reference diameter of 20 mm. Its rounded outer end contributes to the clean, understated design.

The product is presented with zinc alloy or aluminum alloy material options, allowing buyers to inquire about different material configurations according to their project requirements.

The supplied reference engineering sheet illustrates a satin metallic appearance and identifies satin nickel, satin chrome, polished chrome, and matte black as typical finish options for comparable products.

The actual availability of each material and finish combination must be confirmed with DEGOL.

According to the reference specification, the LH1052 has an overall lever length of approximately 126 mm, a projection of approximately 63 mm, and a round mounting rose approximately 53 mm in diameter and 10.5 mm thick.

The curved connecting neck has a reference diameter of 18 mm, while the main cylindrical grip has a reference diameter of 20 mm.

The drawing also identifies an 8 × 8 mm square spindle connection, a reference door thickness range of 35–54 mm, a non-handed configuration, and a concealed-fixing round rose.

With its balanced combination of straight lines and gentle curves, the LH1052 can complement modern residential interiors, apartment projects, office spaces, and compatible hospitality or commercial interior doors.

Jiangmen Degol Hardware Co., Ltd. welcomes wholesale and OEM / ODM inquiries from architectural hardware importers, door handle distributors, building material suppliers, door manufacturers, contractors, and international hardware brands.

Product Definition

What Is the DEGOL LH1052 Straight Tubular Door Lever Handle?

The DEGOL LH1052 is a modern lever-on-round-rose door handle design characterized by a smooth curved connecting neck and a straight cylindrical grip.

The lever is intended to operate a compatible latch or lock mechanism through a square spindle connection.

The LH1052 combines two principal geometric elements:

1. A Smooth Curved Neck

The handle begins with a rounded connecting section extending outward from the mounting rose.

The neck curves gradually before transitioning into the straight gripping section.

2. A Straight Cylindrical Grip

The main lever extends horizontally with a consistent round-bar appearance.

The drawing identifies a reference grip diameter of 20 mm.

This combination creates a contemporary handle design with a softened L-shaped profile.

Main Structural Features

Smooth Elbow Connection

The curved connecting neck forms a flowing transition between the round rose and the horizontal lever.

Straight Tubular-Style Lever

The gripping section has a cylindrical, tube-like appearance.

The illustration does not establish whether the lever is hollow or solid.

Rounded Outer End

The outer end has a softly rounded profile without a sharp square-cut edge.

Round Mounting Rose

The handle is shown with a circular decorative rose.

Concealed Fixing

The reference specification identifies a concealed-fixing round rose configuration.

The exact fixing method requires confirmation.

Square Spindle Connection

  • Product specification table

All dimensions are expressed in millimeters.

1. Overall Lever Length – 126 mm

The reference specification identifies an overall lever length of 126 mm.

This dimension is useful for preliminary product comparison and architectural hardware selection.

The final measurement datum should be confirmed with an approved drawing.

2. Lever Projection – 63 mm

The reference table identifies a lever projection from the door face of 63 mm.

This measurement is relevant when evaluating hand clearance and the installed position of the lever.

The precise projection measurement points require verification.

3. Lever Tube Diameter – Ø20 mm

The main gripping section has a nominal reference diameter of 20 mm.

This cylindrical profile gives the LH1052 its clean, straight-bar appearance.

The term “tubular” describes the visible geometry and does not confirm a hollow internal construction.

4. Neck / Shank Diameter – Ø18 mm

The curved connecting neck has a nominal reference diameter of 18 mm.

This slightly narrower section creates a visual transition into the 20 mm gripping bar.

5. Smooth Curved Elbow

The top view illustrates a continuous curved transition between the mounting axis and the straight gripping section.

The exact bend radius is not specified.

The smooth elbow is a key visual characteristic of the LH1052.

6. Round Rose Diameter – Ø53 mm

The front view and specification table identify a round rose diameter of 53 mm.

This circular base complements the handle's cylindrical geometry.

7. Rose Thickness – 10.5 mm
