This knob from Schaub and Company provides a square form that helps align sightlines on face frames and flat-panel fronts. The 1-3/8 inch dimension sets a clear hand contact area, which helps installers plan layout spacing and center-to-edge distances on doors and drawer fronts. Signature Satin Brass finish establishes the color tone for the job, supporting coordination with other brass decorative hardware and moldings in the space. As part of the Schaub knobs product class, this piece fits projects where decorative hardware is expected to double as a design feature and a daily touchpoint. The named Quadrato identity helps distinguish this square knob style for repeat ordering or matching on future phases.

That M4 specification matters when selecting screws and drilling pilot holes so the knob seats properly against the surface. The 1-3/8 inch size informs where to position the mounting hole, especially on narrow rails where edge distance is limited. This Schaub Quadrato square knob format gives installers a predictable geometry, which helps maintain consistent alignment when repeating the same layout pattern across a full kitchen, bath, or built-in run.

The square profile works on flat-paneled or shaker-style fronts where straight lines are part of the overall design language.
