Product Introduction

The DEGOL LH1051 Modern Straight Cylindrical Door Lever Handle on Round Rose is a contemporary architectural door hardware design featuring a clean cylindrical lever, a short connecting neck, a circular mounting rose, and a refined satin nickel finish.

Designed for modern interior doors, the LH1051 emphasizes simplicity, balanced proportions, and understated architectural styling.

Unlike curved, twisted, or sculpted lever handles, the LH1051 uses a straight round-bar gripping section with a smooth cylindrical surface and a softly rounded end.

The handle is connected to its circular mounting rose through a short neck with an angled transition. This creates a distinctive L-shaped overall configuration while maintaining a clean, minimalist appearance.

The supplied product engineering sheet identifies zinc alloy or aluminum alloy as the material options and satin nickel as the specified finish.

The actual alloy grade, manufacturing process, and availability of each material version should be confirmed before ordering.

According to the supplied engineering drawing, the LH1051 has a reference overall length of 128 mm, a projection of 64 mm, and a cylindrical lever diameter of approximately 19 mm.

The round mounting rose is specified as approximately Ø52 mm with a thickness of 10 mm.

Additional reference dimensions include an 18 mm neck length, 16 mm neck height, R9 lever-end radius, Ø38 mm fixing base, and 8 × 8 mm square spindle.

The drawing identifies a reference door thickness range of 35–45 mm and an intended application for interior doors.

With its streamlined shape and satin nickel appearance, the LH1051 may be considered for modern residential interiors, apartments, offices, hospitality projects, and architectural hardware collections.

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