DG-BT40-CR glass door knob is a Sugatsune DG-BT Series decorative knob designed for glass doors where a 40 mm diameter chrome knob suits the layout. The DG-BT Series identity ties this knob into Sugatsune Americas matching decorative hardware families, which helps keep hardware styles consistent across multiple openings. The knob is made of brass, which supports solid-feeling operation on a glass panel while maintaining a refined appearance suited to decorative hardware installations. A chrome finish on this brass knob presents a bright, neutral surface that coordinates easily with many hinge and lock finishes on glass doors. The SAP description identifies this knob specifically as a glass door knob with 40 mm diameter, which gives installers a clear size reference when planning sightlines and hand clearance on cabinet or display doors.
The DG-BT40-CR knob is specified for glass thickness from 5/16 inch to 1/2 inch, which sets a clear working range for door panel selection on cabinets or display cases. This glass thickness range allows the same knob to be used on lighter display doors and on heavier glass doors within that band, simplifying hardware selection across a project. A 1/2 inch cut out diameter is required in the glass, so glaziers and installers can coordinate drilling to that size before final hardware installation. By matching the cut out diameter and glass thickness to these values, the knob, back plate, washers, and tube support a centered, balanced grip on the glass door.
The DG-BT Series DG-BT40-CR knob is suited to glass doors that fall within the 5/16 inch to 1/2 inch glass thickness range, aligning the hardware with many cabinet and showcase door constructions. The 40 mm diameter gives this knob a substantial footprint on the glass surface, which is helpful on taller doors where users benefit from a more generous handhold. The knob, back plate, washers, and tube layout is designed for a 1/2 inch cut out diameter in the glass, so fabricators can plan their drilling patterns around that consistent requirement. Because the knob is identified specifically as a glass door knob, its sizing and interface work with glass panels rather than wood or metal doors in typical decorative hardware settings.
The specified 5/16 inch to 1/2 inch glass thickness range gives installers a known tolerance band, supporting repeatable results across multiple doors in the same installation. When every panel is drilled with a 1/2 inch cut out diameter, the knob, back plate, washers, and tube align consistently, which supports even pressure distribution across the glass surface. Using a brass knob body provides a stable mounting core for this hardware set, contributing to consistent feel across doors that share the same DG-BT Series components. The chrome finish on the brass knob presents a uniform visual across all glass doors using DG-BT40-CR, which helps projects maintain a cohesive look from one cabinet or display case to the next.
