Deltana KRB175 Round Knob with Groove, Heavy-Duty, 1-3/4" Diameter, Solid Brass

The KRB175 is a single-hole round knob, so it mounts through one bore in the door or drawer front. If the cabinet already has knobs on single holes, it drops onto them. If the fronts are drilled for two-hole pulls on centers, a knob won't cover that prep and you'd want a pull instead, such as the Schaub 10040 Cafe Modern Oval knob with 7/8 inch center to center, which mounts on two holes.

1-3/4 inches in diameter, which is oversized for a cabinet knob. On full-overlay kitchen doors and large drawer banks it reads in scale; on small doors, narrow face frames, or slim drawer rails it will look heavy and can crowd the edge. If you want something smaller in the same round shape, the Schaub 131 Artifex knob is 1-1/2 inches and the Schaub 1200 Modo is 16 mm.

No. The KRB175 is a cabinet knob, not a door knob. It has no spindle, latch, or rose and won't operate a bore-hole lockset. It mounts to a cabinet door, drawer front, or a similar thin panel with a single screw through the back. For a passage or closet door you need a full knobset with a latch.

The Schaub 131 Artifex is a round cabinet knob with a 1-1/2 inch diameter, so it keeps the round profile while dropping a quarter inch of face off the Deltana KRB175, which is a 1-3/4 inch round knob in solid brass. On a run of shallow drawer fronts or narrow stiles where a 1-3/4 inch knob crowds the edge, the 1-1/2 inch Artifex is the direct round substitute. The Orca Hardware CK-18032 Mission is also a round cabinet knob if a Mission-style face suits the room.

Not necessarily. The Schaub 10040 Cafe Modern Oval and the Schaub 10030 Cafe Modern Oval Slot are both 1 inch knobs carrying a 7/8 inch center to center dimension, so the drilling for them is a spaced pattern rather than the single centered hole a round knob such as the Deltana KRB175 sits on. If existing doors are already bored for a single knob screw, the round Deltana KRB175 or the Schaub 131 round Artifex drops into that hole; the Cafe Modern pair calls for its own layout. Confirm the boring on a sample door before ordering a fleet quantity.

Solid brass throughout, and Deltana builds the KRB175 as a heavy-duty knob. Solid brass won't crack or delaminate the way plated zinc and plastic knobs do when a tenant yanks a drawer, so it repairs well across a unit turn. Deltana rates it for residential use.

Nine finishes: PVD Polished Brass, Polished Brass, Antique Brass, Oil Rubbed Bronze, Brushed Nickel, Antique Nickel, Polished Chrome, Brushed Chrome, and Paint Black. If the knobs are going somewhere humid, a bath vanity or a coastal property, the PVD Polished Brass is the one to specify. PVD is a hard vacuum-deposited coating rather than a lacquer, so it resists the tarnishing and lacquer flaking that plain Polished Brass shows over time.

For solid brass in another brand, Delaney Hardware makes a Solid Brass Cabinet Knob in its Cabinet Knobs series. If you want a wider style range under one collection so the units stay coordinated, Emtek's Schaub Collection covers it, the Emtek 8665 SELECT, Allerton, Art Deco, and Astoria Glass knobs all being cabinet knob/pull. What matters for a fleet is picking one finish name and holding it across every order, because finish names don't cross brands reliably.

Deltana ships the KRB175 with a standard machine screw for typical cabinet door and drawer front thickness. Thick shaker stiles, applied panels, or a knob going onto a drawer with a thick false front can run the screw short. Cabinet knob screws are 8-32 thread, so a longer 8-32 machine screw from any hardware source makes up the difference; measure your front before install.

The Emtek Astoria Glass Cabinet Knob in the Schaub Collection is the glass-bodied option; the Deltana KRB175 is solid brass and is not offered with a glass face. Property managers matching an existing traditional kitchen often want the glass knob on upper cabinets and a metal knob elsewhere, and those two cannot be filled from one part number. Order the Astoria where the glass look is required and the KRB175 where a brass body is specified.

The Deltana KRB175 is designated for residential use, and it is built heavy-duty in solid brass, which is what carries it through the traffic of a multi-family turn or a hospitality guest room casework package. The Orca Hardware CK-19032 Whistler and CK-18032 Mission are cabinet knobs in the same class of part. For a specifier writing a cabinet hardware schedule, the deciding factor across this group is body material and construction rather than a commercial designation, so the solid brass heavy-duty KRB175 is the one to hold against a high-cycle drawer bank.

The groove is a recessed band turned into the face of the knob, giving the KRB175 a stepped traditional profile rather than a smooth dome. It's a look, not a function, and it catches light and shadow so the knob reads more detailed on a painted or stained door. If you'd rather have plain and modern, the Orca CK-18032 Mission round knob and the Emtek Art Deco cabinet knob are round knobs in different styling.

All three are cabinet knobs. The Emtek Art Deco and the Emtek Allerton are separate design collections in the Schaub Collection, each with its own face treatment, while the Deltana KRB175 is a plain round knob with a groove cut around the face, 1-3/4 inch in diameter and solid brass. The Emtek 8665 Select is a further collection in the same family. Choose by which face the millwork or the existing hardware calls for; none of the four substitutes visually for another.
