Schaub 550 1-1/4" Diameter Heathrow Cabinet Knob

The Heathrow 550 measures 1-1/4 inch in diameter, which is the common all-purpose cabinet knob size and works on doors and small to medium drawers. For wide or heavy pot drawers most designers switch to a pull rather than a knob. If you specifically want a larger knob, the Deltana KRB175 round knob with groove is 1-3/4 inch diameter solid brass.

A single knob mounts through one hole, so as long as the old knobs were single-hole knobs on an 8-32 screw (the standard), the Heathrow 550 goes straight back into the same bore. What it will not cover is a two-hole pull layout, since the 3/4 inch base is too small to hide a second hole.

The Schaub 550 Heathrow knob is a contemporary style. For a more traditional or period look, the Emtek Art Deco cabinet knob and the Emtek Allerton cabinet knob are both from the Schaub collection, and the Emtek Astoria glass cabinet knob uses a glass body instead of metal. For a craftsman or mission-influenced door, the Orca Hardware CK-18032 Mission round cabinet knob is a round knob in the 18-Mission collection.

The Schaub 550 Heathrow knob is a 1-1/4 inch diameter solid brass cabinet knob. If a larger knob face suits the door or drawer better, the Deltana KRB175 is a solid brass round knob with a groove detail in a 1-3/4 inch diameter, described as heavy-duty. The half-inch difference in diameter changes the visual weight on a large drawer front noticeably, so property managers matching knobs across a kitchen should pick one diameter and stay with it.

Projection is 1 inch, with a 3/4 inch base where it meets the door. That gives roughly enough finger clearance for a gloved hand and keeps the knob clear of an adjacent frame. It matters most on inset doors next to a wall return or on drawers below a countertop overhang.

Five finishes: Polished Chrome, Brushed Nickel, Matte Black, Polished Nickel, and Signature Satin Brass. If you are matching pulls on the same run, stay inside the Heathrow collection so the finish batch and profile line up.

Solid brass is the base material, not zinc die cast. For multi-family or hospitality turnovers that matters because brass threads hold up better to repeated removal and reinstallation than cast pot metal, and the finish sits on a stable substrate.

The Delaney solid brass cabinet knob is a plain solid brass knob from Delaney's cabinet knobs series, with no collection styling to match. The Schaub 550 Heathrow is also solid brass but carries a defined contemporary profile and comes in Polished Chrome, Brushed Nickel, Matte Black, Polished Nickel and Signature Satin Brass, which matters when the knob has to match other finished hardware in the room.

The Schaub 550 Heathrow knob ships with an 8/32 x 1 inch machine screw, the standard cabinet knob thread. The Orca Hardware CK-19032 Whistler and CK-18032 Mission are both single-hole cabinet knobs as well, so any of them mount to an existing single bore. Confirm screw length against your door or drawer front thickness when swapping brands on thick slab fronts.
