The DGOL LH1128 Modern Cylindrical Door Lever Handle with Decorative Ring on Round Rose is a contemporary architectural door hardware design featuring a straight cylindrical lever, a distinctive decorative ring near the handle tip, a rounded outer end and a circular mounting rose.
Designed for modern minimalist interiors, the LH1128 combines a smooth cylindrical gripping profile with subtle decorative detailing. The narrow accent ring near the outer end creates a refined visual distinction while maintaining the clean, straight geometry of a modern tubular lever handle.
Unlike conventional plain cylindrical door handles, the LH1128 incorporates a decorative double-line ring detail positioned near its rounded tip. This subtle design element adds character without compromising the minimalist appearance of the overall lever.
The product also features a tapered connecting neck that provides a smooth transition between the round rose and the main cylindrical gripping section.
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, making the LH1128 a design that can be evaluated by architectural hardware wholesalers, door manufacturers, international importers and private-label building hardware brands.
According to the supplied engineering reference drawing, the LH1128 features a 130 mm overall lever length, 64 mm projection from the door face, Ø52 mm round rose and 10 mm rose thickness.
The main cylindrical gripping section has a reference diameter of Ø18 mm, while the outer lever tip has a reduced diameter of Ø15 mm.
A 3 mm decorative ring detail is located approximately 16 mm from the outer tip, and the rounded end is identified with an R7 reference.
Additional reference specifications include an 18 mm neck length, 16 mm neck height, Ø38 mm mounting base, 8 × 8 mm square spindle and suitable door thickness of 35–45 mm.
The LH1128 is specified for compatible interior door applications and features a concealed fixing arrangement.
