Emtek Diamond Glass Cabinet Knob, Schaub Collection

Ten finishes are made across the Diamond glass knob: Oil Rubbed Bronze (US10B), Polished Nickel (US14), Satin Nickel (US15), Pewter (US15A), Flat Black (US19), Polished Chrome (US26), Polished Brass Lifetime (US3), Unlacquered Brass (US3NL), Satin Brass (US4), and French Antique (US7). Two are worth flagging for a spec: Unlacquered Brass is a living finish that will patina with handling, and Polished Brass Lifetime is the coated version that holds its shine. If you're matching cabinet knobs to door hardware elsewhere in the house, those US codes are the ones to match on.

No, not without filling holes. The Diamond glass knob mounts on one screw through a single bore, so swapping from a pull that uses two holes on a center-to-center spacing leaves the second hole exposed. If you're replacing pulls and want to reuse the existing drilling, you need another pull on the same center-to-center, not a knob. Schaub's 10030 and 10040 Cafe Modern knobs are the exception worth knowing about, since those are 1 inch knobs listed with a 7/8 inch center to center.

Two things settle the order: diameter and finish. Emtek runs a separate base number per size in the Schaub Collection numbering, then appends the US finish code. The 1 inch in Polished Nickel is SPC86003US14, the 1-1/4 inch in Oil Rubbed Bronze is SPC86012US10B, and the 1-3/4 inch in Satin Nickel is SPC86209US15. So the size lives in the base number, not in a suffix, which is what trips people up when they try to reorder a matching knob in a different diameter.

The Deltana KRB175 is a heavy-duty solid brass round knob with a groove, 1-3/4 inch diameter. The Emtek Diamond cabinet knob is also offered in a 1-3/4 inch size in brass with a glass face, so the two land at the same diameter with different faces: the Deltana is all metal, the Emtek Diamond pairs a brass body with a glass top. If a kitchen or vanity run needs the 1-3/4 inch scale but the glass is not wanted on high-traffic doors, the KRB175 holds the size.

Schaub makes two 1 inch Cafe Modern knobs: the 10040 Cafe Modern Oval cabinet knob with 7/8 inch center to center, and the 10030 Cafe Modern Oval Slot cabinet knob, also 7/8 inch center to center. Both match the 1 inch size the Emtek Diamond cabinet knob is offered in, and both give an oval metal face rather than the Diamond's glass top. The 10030 carries a slot detail across the face; the 10040 is the plain oval.

The Schaub 10030 Cafe Modern Oval Slot knob is listed with a 7/8 inch center to center, which is a two-hole pattern rather than a single-hole knob mount. The Emtek Diamond cabinet knob ships with a mounting screw for a single-hole knob bore. Swapping the 10030 in over existing Diamond holes means new boring in the door or drawer front, so it is not a hole-for-hole replacement even though both are called cabinet knobs.

A mounting screw ships with each knob, so nothing extra is needed for a standard cabinet door or drawer front. On thicker fronts, or where a drawer box back adds material behind the face, the supplied screw can come up short and a longer replacement screw of the same thread is what you'd source locally.

The knob body is glass with brass hardware behind it, which is why the finish is called out in US codes. Brass is the substrate carrying the mounting screw, and the glass is the visible face. That combination is what puts it in the Glass and Porcelain family rather than the all-metal knobs.

It comes down to the face material and how it wears. The Diamond is a glass-faced knob on brass, so it reads as a decorative or period detail in a kitchen or bath. A solid brass round knob, like the Delaney solid brass cabinet knob or the Schaub 131 1-1/2 inch round Artifex, gives you a metal face that takes knocks better and is easier to standardize across a lot of openings. If the look is the reason you're here, the glass is the point; if the job is durability across a fleet of units, go metal.

For a similar footprint without glass, the Schaub 131 Artifex is a 1-1/2 inch round knob and the Deltana KRB175 is a 1-3/4 inch round knob with a groove in solid brass. Going smaller, the Schaub 1200 Modo is a 16 mm knob, which is closer to a compact drawer knob than a door knob. All three drill the same way as the Diamond, one hole through the face.

Yes, and it's the usual way it gets spec'd. Every one of the three diameters is built in the same ten finishes, so a 1 inch on drawers and a 1-3/4 inch on the pantry in the same US code will match exactly. The one caution is Unlacquered Brass: it's a living finish, so knobs installed at different times, or handled more in one spot, will patina at different rates.

The Schaub 131 is a 1-1/2 inch round Artifex cabinet knob. The Emtek Diamond cabinet knob is offered in 1 inch, 1-1/4 inch, and 1-3/4 inch, so the 131 sits at a diameter between the Diamond's middle and largest sizes and will not drop into a run specified at any of the three Diamond sizes without changing the visual scale. It is a cabinet knob for the same application, but it is not a size-for-size swap.

Orca Hardware offers the CK-18032 Mission round cabinet knob from the 18-Mission collection and the CK-19032 Whistler cabinet knob from the 19-Whistler collection, both cabinet knobs. Delaney also lists a solid brass cabinet knob. The Emtek Diamond is a brass knob with a glass face from the Glass and Porcelain collection, so for a Mission or craftsman cabinet package the Orca collections carry the style through a full run where the Diamond's glass would read as a different design language.

The Deltana KRB175 is described as a heavy-duty solid brass round knob. The Emtek Diamond cabinet knob is a brass knob with a glass face and is designated residential. On unit turns and corridor casework where the same knob gets pulled hundreds of times a week, the all-brass KRB175 puts no glass in the wear path; where the cabinetry is a model unit or an owner-occupied residence and the finish is part of the sell, the Diamond's glass face is the point.
