Delaney Bi-Fold Cabinet Door Knob, Satin Nickel (US15)

Both are the same 1-3/16 inch diameter knob in satin nickel; the difference is projection and coverage. With the back plate the knob stands 1-1/2 inches off the door face and the plate covers a 1-3/4 inch circle. Without the plate it projects 1-1/4 inches. Pick the back plate version when you are replacing older hardware and need to hide a worn ring or oversized hole in the bi-fold face; pick knob-only on new or clean doors.

The Delaney bi-fold cabinet door knob is zinc, with a 1-3/16 inch knob diameter and a 1-3/4 inch backplate. If you want solid brass in a similar round profile, the Deltana KRB175 is a round knob with a groove in solid brass at 1-3/4 inch diameter. The Deltana is a plain round knob rather than a bi-fold knob with a backplate option, so the mounting hardware and projection will differ.

The Delaney bi-fold cabinet door knob is built for bi-fold applications and is offered either as knob only or with a back plate. Standard cabinet knobs such as the Schaub 10030 Cafe modern oval slot knob at 1 inch diameter with 7/8 inch center to center, the Schaub 131 Artifex round knob in Britannium at 1-1/2 inch diameter, and the Orca Hardware CK-18032 Mission round cabinet knob are drawer and door pulls without bi-fold mounting provisions, so confirm the fastener length and door thickness before treating them as drop-ins.

The back plate version covers a 1-3/4 inch circle, so it hides a small ring of wear or a slightly oversized bore around a standard single-screw knob hole. Knob-only covers roughly the 1-3/16 inch footprint of the knob itself. If the old hardware left marks wider than 1-3/4 inches, this won't conceal them and you'll need to patch and refinish.

Zinc substrate with a satin nickel (US15) finish. Cast zinc is the standard material for volume cabinet and bi-fold knobs, heavier and more dent-resistant than stamped or plastic hardware and appropriate for apartment turns and light commercial closet doors. For a solid brass knob instead, the Deltana KRB175 round knob with groove is a heavy-duty 1-3/4 inch solid brass option.

Yes. It is a single-screw cabinet knob at 1-3/16 inches across, which is a common cabinet-door size, so it works on cabinet fronts and drawers as well as closet bi-folds. Just remember drawers and cabinet faces are usually thinner than a bi-fold panel, so confirm your screw length suits the stock you are mounting into.

For a fleet of bi-fold and closet doors, a single zinc knob in satin nickel in one diameter is what you want, and you can run it with or without the back plate door by door depending on what the old hardware left behind. That lets you keep one part number on the shelf while still handling openings that need hole coverage.

The Delaney bi-fold cabinet door knob has a 1-3/16 inch knob diameter and projects 1-1/4 inch without the backplate. For a smaller footprint, the Schaub 1200 Modo is a 16 mm cabinet knob in zinc and aluminum construction, and the Schaub 10040 Cafe Collection modern oval knob is 1 inch diameter with 7/8 inch center to center in solid brass. Both are standard cabinet knobs rather than bi-fold knobs.

The Delaney bi-fold cabinet door knob is a plain round zinc knob in satin nickel (US15). For more decorative programs, Emtek's Schaub Collection offers the Art Deco cabinet knob, the Allerton cabinet knob, and the Astoria glass cabinet knob, and Emtek 8665 is part of the Emtek SELECT cabinet knob and pull line. The Orca Hardware CK-19032 Whistler knob is another styled option from the 19-Whistler Collection.

The Schaub 131 Artifex round cabinet knob is 1-1/2 inch in diameter in Britannium. The Delaney bi-fold cabinet door knob has a 1-3/16 inch knob diameter, though it can be ordered with a 1-3/4 inch backplate, which gives it the wider face at the door surface and covers existing fastener marks. Without the backplate the Delaney projects 1-1/4 inch, and with it 1-1/2 inch.

Several directions in the same size class. The Schaub 131 Artifex is a round knob in Britannium at 1-1/2 inch diameter, a bit larger and a darker finish. The Emtek Art Deco and Emtek Astoria glass knobs from the Schaub collection go decorative. For a craftsman look, the Orca Hardware CK-18032 Mission round knob. The Schaub 1200 Modo is a small 16 mm zinc and aluminum knob if you want something much more minimal than the 1-3/16 inch Delaney.

A knob is the usual call on a bi-fold because you grab it and pull the leaf out and across, and a round knob takes that pull from any angle. Center-to-center pulls like the Schaub 10030 or 10040 Cafe knobs, which mount on a 7/8 inch center-to-center, suit drawer fronts and flat cabinet faces where you want a directional grip. On a folding closet door, the round knob is the simpler fix.
