Emtek Tuscany Bronze Octagon Cabinet Knob, Schaub Collection

Three diameters: 1 inch, 1-1/4 inch, and 1-3/4 inch. The 1 inch works on drawer fronts and smaller doors where you want the knob to sit quietly; the 1-3/4 inch is a statement size for large drawer banks and tall pantry doors. All three sizes are offered in both finishes, Flat Black Bronze (FB) and Medium Bronze (MB), so you can mix sizes across a kitchen and keep one finish throughout.

A mounting screw is included with the knob, so nothing extra is needed for a standard single-hole cabinet knob installation. If your doors or drawer fronts are thicker than usual (applied moldings, double-thickness fronts, or a back panel behind the front), the supplied screw may be short and you would source a longer 8-32 machine screw to suit.

Residential. Emtek classes the Tuscany Bronze Octagon knob as residential hardware, so it belongs on kitchens, baths, built-ins, millwork, and multi-family unit interiors rather than on a high-traffic institutional casework spec. If you are buying for a hotel or apartment renovation it is fine on unit cabinetry; for back-of-house or public-area casework that gets industrial cycles, look at a heavy-duty solid brass knob instead, such as the Deltana KRB175.

In most cases yes. A cabinet knob mounts through one hole, so swapping knob for knob reuses the existing bore. What changes is the footprint on the door face: at 1-3/4 inches the Octagon base covers considerably more area than a small 1 inch knob, which is useful if the old hardware left a wear ring or a paint shadow. Going the other way, from a large knob down to the 1 inch, may expose that shadow. If you are replacing a two-hole pull, the single knob hole will not line up with the old pair and you will be filling and re-drilling.

The Deltana KRB175 is a round knob with a groove in solid brass at 1-3/4 inch diameter, so it lands at the same size as the largest Emtek Octagon Tuscany Bronze knob while reading as a round face rather than a faceted octagon. Both are brass-bodied knobs. If the cabinet run needs the 1-3/4 inch presence but the design direction moved away from the faceted Tuscany look, the KRB175 covers the size; if the octagon geometry is the point, stay with the Emtek.

Two Schaub Cafe knobs are built at 1 inch: the 10040 Cafe Modern Oval with 7/8 inch center to center, and the 10030 Cafe Modern Oval Slot, also 7/8 inch center to center. Both are oval-faced rather than octagonal, and the 10030 carries a slot detail across the face that the 10040 does not. The Emtek Octagon's 1 inch size sits in the same footprint, so any of the three will read at similar scale on a drawer front.

No. The KRB175 is a round knob with a groove, while the Emtek Octagon is a faceted octagon face in the Tuscany Bronze collection, offered in Flat Black Bronze and Medium Bronze. They overlap at 1-3/4 inch in size only. For a property manager replacing a few damaged knobs across an existing cabinet run, the size match will not carry the appearance match; order the Emtek Octagon in the finish already on the doors.

The Deltana KRB175 is described as a heavy-duty solid brass round knob at 1-3/4 inch, which is the one in the group carrying a heavy-duty designation. The Emtek Tuscany Bronze Octagon is a brass residential cabinet knob, so it fits homes, model units, and light-use millwork rather than a heavy-cycle commercial run.

Two distinct bronze tones, both offered across the full size range. Flat Black Bronze (FB) reads as a dark, near-black bronze and pairs with black plumbing and matte black appliances. Medium Bronze (MB) is a warmer, mid-tone brown bronze that sits closer to traditional oil-rubbed hardware. Both belong to the same Tuscany Bronze collection, so if you are matching knobs to Emtek Tuscany door hardware already in the house, pick the finish code that matches the existing lettering rather than matching by eye.

The Octagon is a knob, a single-post piece that mounts through one hole. It is not a two-post pull, so it will not drop into a pair of existing pull holes with center-to-center spacing. If you need a pull for the drawers to go alongside these knobs, choose an Emtek Tuscany Bronze pull in the same finish code, FB or MB, so the bronze tone matches across the run. Where you want the knob-and-pull look on a single hole, the 1-3/4 inch Octagon is large enough to hold its own next to drawer pulls.

Depends which way you want to go. For a plainer round profile in solid brass, the Delaney Solid Brass Cabinet Knob or the Deltana KRB175 in a 1-3/4 inch diameter give you the same weight in a simpler shape, and the Deltana matches the Octagon's largest size. For a craftsman or mission look, Orca Hardware's CK-18032 Mission round knob is the closer stylistic cousin. If you want something contemporary rather than traditional bronze, Schaub's 1200 Modo knob at 16 mm is the small modern option, and the Schaub 131 Artifex is a 1-1/2 inch round. The Octagon's faceted geometry is what it brings that none of those do.

The Delaney Solid Brass Cabinet Knob is a solid brass knob in Delaney's cabinet knob series, and the Deltana KRB175 is solid brass at 1-3/4 inch. The Emtek Octagon is brass as well and ships with a mounting screw, so all three share the same material class for a cabinet run. The Emtek is the one carrying the Tuscany Bronze finish treatment in Flat Black Bronze and Medium Bronze.

They are the same size and mounting geometry: both are 1 inch Cafe Modern knobs with 7/8 inch center to center. The 10040 is the plain Modern Oval; the 10030 is the Modern Oval Slot, which adds a slot detail to the oval face. For a kitchen standardizing on one profile across many doors, the two are interchangeable dimensionally and the choice is about whether the slot detail belongs on the face.

The Schaub 131 Round Artifex is 1-1/2 inch, and the Deltana KRB175 is 1-3/4 inch in solid brass. The Emtek Octagon also reaches 1-3/4 inch. On wide drawer fronts where a 1 inch knob disappears, those are the sizes to work from, with the Schaub 131 and the Deltana both in round profiles and the Emtek in the faceted octagon face.

The Orca Hardware CK-18032 Mission Round is built for that direction as a cabinet knob in the 18-Mission Collection, and the Orca CK-19032 Whistler is a cabinet knob in the 19-Whistler Collection for a rustic lean. The Emtek Octagon belongs to the Tuscany line and reads faceted and traditional rather than mission. If the rest of the room is mission detailing, the Orca CK-18032 is the nearer visual match.

They are separate items. The Schaub 10030, 10040, 1200 Modo, and 131 Round Artifex are their own cabinet knob models with their own profiles and sizes, from the Cafe Modern Oval at 1 inch up to the 131 Round Artifex at 1-1/2 inch. The Emtek Tuscany Bronze Octagon is the faceted octagon in the Tuscany Bronze collection. Ordering a Schaub 131 expecting an Octagon knob will bring a round Artifex face instead.

The Octagon knob comes out of Emtek's Schaub collection within the Tuscany Bronze family. Practically, that means it coordinates with other Tuscany Bronze pieces in FB and MB, and it sits in a different design language from Schaub's own-brand knobs like the 10030 and 10040 Cafe Modern ovals or the 1200 Modo, which are contemporary rather than traditional. Do not expect finish names to cross between the Emtek Tuscany codes and Schaub's own finish range.

Purely mechanical. The Octagon is a passive cabinet knob with a mounting screw, no electronics, no battery, and no wiring of any kind. It installs with a screwdriver through the existing knob bore.
