Schaub 56 City Lights Round Disc Glass Knob

The Schaub 56 City Lights knob uses an 8/32 x 1 inch machine screw, which is the standard cabinet knob thread. A 1 inch screw covers typical 3/4 inch doors and drawer fronts with room to spare. If you are mounting to a thicker slab front, a false front, or a door with an applied panel, you will need a longer 8/32 screw, which is a stock item at any hardware counter. The thread size itself does not change.

In most cases yes. A cabinet knob mounts through a single hole and this one takes the standard 8/32 machine screw, so it drops into the existing bore left by nearly any single-hole knob. What to watch is the footprint: the base is 7/8 inch, so if the knob you are pulling off had a wider base it may have covered wear or finish shadow on the door face that the smaller base will not hide.

The Emtek Astoria glass cabinet knob in the Schaub collection is the nearest glass-topped alternative. Both are cabinet knobs with a glass face, so either will read as a glass knob across a kitchen or vanity run. The Schaub 56 City Lights is a round disc glass knob measuring 1-3/8 inch in diameter with a 1-1/8 inch projection over a 7/8 inch base, on a solid brass body, in a contemporary style. The Astoria is offered as a knob/pull in Emtek's Astoria series. If you are matching an existing City Lights installation, stay with the 56; if you want a faceted or period glass profile instead, the Astoria is the one to look at.

For a solid metal knob with no glass face, look at the Delaney solid brass cabinet knob or the Deltana KRB175, a heavy-duty round knob with a groove in a 1-3/4 inch diameter and a solid brass body. The Deltana is a full 1-3/4 inch across compared with the 1-3/8 inch diameter of the Schaub 56 City Lights, so it presents a noticeably larger face on the door. Both the Schaub 56 and the Delaney knob are solid brass. The trade-off is purely appearance and grip size - the City Lights gives you a glass disc top, the metal knobs give you a single uninterrupted material.

Projection is 1-1/8 inches from the face of the door or drawer, with a 7/8 inch base at the mounting surface. That is enough clearance to get fingers behind it comfortably, and it matters where cabinets sit close to an adjacent wall, an appliance panel, or a door that swings into the run. Check the swing clearance on any door next to a range or refrigerator before you standardize on it.

Six finishes: Oil Rubbed Bronze, Satin Nickel, Polished Chrome, Polished Nickel, Polished Rose Gold, and Satin Brass. That range covers matching to both warm and cool plumbing and appliance trim, and the polished options pair with the glass face for a brighter look. If you are matching existing hardware across a kitchen or a multi-unit build, order one knob first and compare against the installed finish in the actual light of the room.

The base metal is solid brass, with a glass disc face. Solid brass holds threads better than zinc die cast and stands up to repeated tightening, which matters on rental turns and hospitality properties where hardware gets removed and reset. Glass faces are durable in normal use but will chip if struck hard, so consider that on high-traffic commercial millwork.

If you would rather avoid a glass face entirely, the Deltana KRB175 is a solid brass round knob with a groove at 1-3/4 inch diameter, noticeably larger than the 1-3/8 inch Schaub 56. For a plainer solid brass round, Delaney also makes a solid brass cabinet knob. On the contemporary side, Orca Hardware's CK-19032 Whistler cabinet knob is another round option to compare.

The Schaub 56 City Lights is a contemporary round disc glass knob. If the cabinetry calls for a more traditional or craftsman profile, the Orca Hardware CK-18032 Mission round cabinet knob from the 18-Mission collection and the Emtek Art Deco cabinet knob in the Schaub collection both serve that role, as does the Emtek Allerton knob in the Allerton series. All are cabinet knobs mounting the same way as the 56, so the decision is style rather than function.

The Schaub 56 City Lights uses an 8/32 x 1 inch thread and screw size, which is the standard cabinet knob thread, so alternatives such as the Orca CK-19032 Whistler knob, the Orca CK-18032 Mission knob, or the Delaney solid brass cabinet knob mount into the same single drilled hole in the door or drawer front. Confirm screw length against your door thickness when swapping, since a thicker slab or an added backplate can call for a longer screw than the 1 inch supplied.

The Schaub 56 City Lights is a glass disc knob on a solid brass base and is best suited to residential kitchens, vanities, and light-duty casework where appearance leads. Where the casework sees constant use and a glass face is a liability, the Deltana KRB175 is designated a heavy-duty round knob with a groove, 1-3/4 inch diameter in solid brass, and the larger diameter also gives a fuller grip for gloved hands. Choose the 56 when the finish palette matters and the millwork is front-of-house; choose the KRB175 where the knob will take abuse.

City Lights is Schaub's contemporary line, and the 56 is a plain round glass disc with no facets or cuts, so it reads modern rather than period. If you want a cut or faceted glass knob with a more traditional feel, the Emtek Astoria Glass Cabinet Knob from the Schaub Collection is the glass knob to compare it against.

The Schaub 56 City Lights covers it directly. It is offered in polished rose gold, satin brass, polished nickel, satin nickel, polished chrome, and oil rubbed bronze, so you can hold a single 1-3/8 inch round disc glass knob across a warm or cool palette without switching product lines. If the room needs a matching non-glass knob in the same family of looks, the Emtek Allerton and Emtek Art Deco knobs in the Schaub collection are the adjacent knob styles to pair with.
