Emtek Grayson Glass Cabinet Knob, Schaub Collection

A mounting screw is included with each knob. Standard cabinet knob screws are 8-32 machine screws, so if your door or drawer front is thicker than usual (applied moldings, doubled fronts) you may need a longer 8-32 screw than the one supplied.

Emtek rates the Grayson glass knob as residential. For apartment turns, custom homes and residential remodels it is appropriate. For heavy commercial or institutional casework, where handles take abuse and glass is a liability, a solid metal knob is the better call: the Deltana KRB175 is a heavy-duty solid brass round knob at 1-3/4 inch diameter, matching the larger Grayson size, and Schaub's 131 Artifex round knob in Britannium is a 1-1/2 inch all-metal option.

No. A knob mounts on a single hole; a pull mounts on two holes at a fixed center to center spacing. Swapping pulls for Grayson knobs leaves the second hole exposed unless you plug and refinish the fronts, or drill a new single hole. If you want to reuse two-hole prep, look at a pull instead, or at a knob with stated center to center like the Schaub 10030 Cafe oval slot knob, which is 1 inch diameter with 7/8 inch center to center.

The Deltana KRB175 is a round knob with a groove, 1-3/4 inch diameter, in solid brass. It matches the larger of the two Grayson sizes at 1-3/4 inch, and both are brass-bodied. The difference is the face: the Grayson is part of Emtek's Glass and Porcelain collection with a glass element, while the KRB175 is an all-metal round knob with a machined groove and is described as heavy-duty. Choose the KRB175 when you want the same diameter without a glass face.

They are not interchangeable at the door. The Emtek Grayson ships with a single mounting screw, which is a one-hole knob mount. The Schaub 10030 Cafe Modern Oval Slot knob is 1 inch diameter with 7/8 inch center to center, and the Schaub 10040 Cafe Modern Oval is likewise 1 inch with 7/8 inch center to center - a two-hole bore. If your cabinet fronts are drilled for a single knob hole, the Cafe knobs will require a second hole.

Ten finishes: 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). All ten are offered in both the 1-1/4 inch and 1-3/4 inch diameters. Note that Unlacquered Brass is a living finish and will patina with handling, while Polished Brass Lifetime is coated to hold its shine.

Polished Nickel (US14) is SPC86569US14 in the 1-1/4 inch size and SPC86570US14 in the 1-3/4 inch. The pattern holds across the line: SPC86569 plus the finish code for the small knob, SPC86570 plus the finish code for the large one. Satin Brass, for example, is SPC86569US4 and SPC86570US4.

The Emtek Grayson is brass throughout. If you want a different substrate, the Schaub 131 Artifex is a round cabinet knob in Britannium at 1-1/2 inch diameter, which falls between the two Grayson sizes, and the Schaub 1200 Modo is a 16 mm knob built from zinc and aluminum. Both give you a metal knob in a material other than solid brass.

The Emtek Grayson is a residential glass and porcelain design. For a plainer brass face, the Delaney Solid Brass Cabinet Knob is a straightforward solid brass cabinet knob, and the Orca Hardware CK-18032 Mission is a round cabinet knob from the Mission collection. The Orca CK-19032 Whistler is another round-profile cabinet knob option. All three give you a single-piece metal face with no glass element to chip in a turnover unit.

Working up and down from 1-1/4 inch: the Schaub 10030 and Schaub 10040 Cafe knobs are both 1 inch diameter in solid brass, the Schaub 131 Artifex is 1-1/2 inch in Britannium, and the Deltana KRB175 is 1-3/4 inch solid brass. The Artifex at 1-1/2 inch is the nearest single step up, with the Cafe knobs the nearest step down.

Mixing a glass knob on the perimeter with a metal knob on an island is common practice, but finish names do not cross brands exactly, so plating will not read as a perfect match. Within the same design house, Schaub offers the Cafe Collection modern oval knob (10040, 1 inch diameter, 7/8 inch center to center, solid brass) and the Modo 1200 at 16 mm in zinc and aluminum. Orca's CK-18032 Mission and CK-19032 Whistler round knobs are simpler round profiles if you want a quieter shape alongside the glass.

The knob mounts through a single drilled hole with the supplied screw, so any front that can be drilled and will hold the screw works: wood, MDF, or a stile-and-rail glass door where the knob lands on the wood stile. It is not intended to mount through the glass panel itself.
