Deltana KS125 Modern Square Knob, 1-1/4" x 1-1/4" Solid Brass

The KS125 is a cabinet knob, not a passage or entry door knob. It mounts to cabinet doors and drawer fronts as a pull, so there is no latch, spindle, or rose involved. Solid brass construction, 1-1/4 inch square face.

Deltana classes the KS125 as residential hardware. For apartment turns, single-family, and light multi-family millwork it is the intended application. For high-traffic commercial casework, specify hardware carried as commercial rather than this knob.

No, not without patching. The KS125 is a single-post knob, so it uses one center hole. A pull mounts on two bores at a stated center-to-center spacing, and swapping to a knob leaves both of those holes exposed unless you plug and refinish the face or fit a backplate. Going the other direction, a knob hole to a pull, has the same problem.

The KS125 is a 1-1/4 inch solid brass cabinet knob with a square face. The closest square-faced peer in the same class is the Emtek Art Deco Cabinet Knob from the Schaub Collection, a cabinet knob in Emtek's Art Deco series. If the square geometry is what matters, that is the one to look at; the Orca Hardware CK-18032 Mission Round Cabinet Knob and the Schaub 131 1-1/2 inch Round Artifex Cabinet Knob are round-faced and will read differently on a door face even at similar size.

The KS125 is a single-post cabinet knob. If the drawer fronts are already drilled for two holes, the Schaub 10030 Cafe Modern Oval Slot Cabinet Knob and the Schaub 10040 Cafe Modern Oval Cabinet Knob are both specified with 7/8 inch center to center, meaning they mount on a two-hole pattern rather than a single center bore. That distinction decides whether you are re-drilling drawer fronts or not.

Projection is 1-1/4 inches, and the knob face is 1-1/4 by 1-1/4 inches. That squared-off profile matters if the cabinet sits in a walkway or beside an appliance door swing, since a 1-1/4 inch projection with a square edge catches a pocket or a sleeve more readily than a low round knob.

Seven finishes: Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Paint Black, Polished Chrome, Brushed Chrome, and Brushed Brass. If you are matching existing hardware in a unit, the two chrome options and the two nickel options are the ones people mix up, so pull the finish name off the old piece rather than eyeballing it.

The KS125 is the squared modern profile in solid brass at 1-1/4 inches. For a rounder modern face, the Schaub 10040 Cafe Modern Oval knob is 1 inch, and the Schaub 1200 Modo is a smaller 16 mm knob for lighter drawer fronts. If you want traditional or craftsman instead, the Orca CK-18032 Mission Round and the Emtek Art Deco knob from the Schaub Collection are the closest changes of style. For glass, look at the Emtek Astoria Glass knob.

Solid brass, both the material and the substrate are brass rather than a plated zinc or steel core. That is what lets the finishes wear rather than flake at the edges, which is the usual failure on plated knobs in a rental kitchen.

Yes. The KS125 is solid brass. The Delaney Solid Brass Cabinet Knob, part of Delaney's Cabinet Knobs series, is also a solid brass cabinet knob, so a property manager standardizing on a brass substrate across a unit or a building has a second brass option in the same part class.

Not the same construction. The KS125 is solid brass throughout. The Emtek Astoria Glass Cabinet Knob from the Schaub Collection is a glass cabinet knob in the Astoria series, so the grip face is glass rather than metal. It functions as a cabinet knob in the same way, but it is not a like-for-like swap if the job calls for an all-metal knob to match other brass hardware.

The KS125 is a 1-1/4 inch square solid brass cabinet knob offered in Oil Rubbed Bronze, Polished Nickel, Brushed Nickel, Paint Black, Polished Chrome, Brushed Chrome and Brushed Brass. The Emtek 8665 Select Cabinet Knobs sit in the Emtek SELECT series and are specified as a cabinet knob/pull, which means the family is built to be coordinated across knobs and pulls. Pick the KS125 when the square brass profile and the finish range drive the decision; pick the 8665 when you are buying into the SELECT program.

On a shallow drawer or a narrow false front, a 1-1/4 inch square face reads heavy and can crowd the rail. The KS125 suits full-height door stiles and standard drawer fronts. For small fronts, a smaller knob such as the Schaub 1200 at 16 mm or the 1 inch Schaub 10030 keeps the proportion.

Cabinet knobs mount on a machine screw through the door or drawer front, standard 8-32 thread. On a thick front, a slab door, or a front with an applied panel, the screw supplied with a knob often runs short and you will want a longer 8-32 machine screw. Measure the front thickness before you order the run so you are not stopped mid-install on a whole kitchen.

The KS125 is designated for residential use. The comparable cabinet knobs - the Emtek 8665 in the SELECT series, the Emtek Allerton, and the Orca CK-19032 Whistler - are cabinet knobs in the same category, so for high-traffic commercial millwork the deciding factor is the manufacturer's own duty designation rather than a swap within this group. For multi-family and residential unit turns, the KS125 is in its intended application.
