Schaub 658-ED – Frequently Asked Questions

1) What is the difference between the Schaub 658-ED and 658-R-PB Avalon Bay knobs?
Both are solid brass square knobs from Schaub's Symphony Inlays style, Avalon Bay collection, 1-3/8 inch. The difference is the inlay and the metal finish. The 658-ED pairs Imperial Shell and white mother of pearl with an Estate Dover finish. The 658-R-PB uses red and white mother of pearl with Polished Brass. Pick by what the rest of the kitchen hardware is finished in.
2) Will the Schaub 658 knob cover the holes left by my old knob?
It mounts on a single hole with an 8-32 screw, so it swaps straight onto any existing single-bore knob hole. The footprint on the door is the 3/4 inch base, so it only conceals marks within that 3/4 inch circle. If you are coming off a two-hole pull, it will not cover both centers and you will need to plug and refinish.
3) For a rental turnover where an inlaid knob is too delicate, what should I use instead of the Schaub 658?
The Schaub 658 has an Imperial Shell and mother of pearl inlay face, which is a decorative surface. For high-turnover cabinetry, the Deltana KRB175 is described as a heavy-duty round solid brass knob at 1-3/4 inch diameter, and the Orca CK-18032 Mission and CK-19032 Whistler are plain-face cabinet knobs. All are single-face metal knobs with nothing inlaid to chip.
4) What is a comparable solid brass cabinet knob to the Schaub 658 Avalon Bay knob without the shell inlay?
The Schaub 658 Avalon Bay square knob is solid brass with an Imperial Shell and mother of pearl inlay face, 1-3/8 inch knob diameter. For a plain solid brass knob with no inlay, the Deltana KRB175 is a round knob with a groove in solid brass at 1-3/4 inch diameter, and Delaney also offers a solid brass cabinet knob. Those are smooth metal faces, so the look is metal-only rather than the layered shell inlay of the Avalon Bay.
5) How far does the Schaub 658 knob stick out from the cabinet face?
Projection is 1-1/8 inches from the face of the door or drawer. The knob head measures 1-3/8 inches square and the base is 3/4 inch. That projection matters in a tight galley or where a drawer is next to a walkway, since a knob that sits over an inch proud catches clothing more than a low-profile pull.
6) Is the Schaub 658 knob solid brass or plated pot metal?
Solid brass is the base material, with a shell and mother of pearl inlay set into the square face. That is a different build from a cast zinc knob with a plated coating, and it is why the piece has weight in the hand. For a rental turnover or high-abuse commercial cabinetry, a plain machined knob is the more sensible spend; this one is for finish-grade residential and hospitality millwork.
7) Which Emtek cabinet knob is closest to the Schaub Avalon Bay knob for a decorative kitchen?
The Schaub 658 is part of the Symphony Inlays style in the Avalon Bay collection. Emtek carries the Schaub Collection, and the closest decorative-face option there is the Emtek Astoria Glass cabinet knob, which uses a glass face rather than shell and mother of pearl. Emtek 8665 Select, Allerton, and Art Deco are the other Schaub Collection knobs, all listed as knob/pull function.
8) Is the Emtek 8665 Select a direct substitute for the Schaub 658 Avalon Bay knob?
Not a like-for-like swap. The Schaub 658 is a square knob at 1-3/8 inch diameter with a 1-1/8 inch projection and a 3/4 inch base, functioning strictly as a cabinet knob. The Emtek 8665 belongs to the Emtek SELECT series and is listed as a cabinet knob/pull, so its footprint and mounting differ. Both take standard cabinet screws, but confirm the face size against your existing knobs before mixing them on the same run of doors.
9) Can I match the Schaub Avalon Bay look with Emtek hardware on the rest of the job?
Yes, Emtek sells Schaub Collection cabinet hardware, so you can carry a coordinated program across a house. The Emtek SELECT 8665 cabinet knobs and pulls, the Allerton knob, the Art Deco knob, and the Astoria glass knob are all in Emtek's Schaub Collection and work as companion pieces where you want a different face on pantry or island cabinets.
10) Is a 1-3/8 inch square knob big enough for large drawer fronts?
At 1-3/8 inches square with a 1-1/8 inch projection, the 658 gives a full hand grip and reads well on doors and small to mid drawers. On wide drawer banks, most designers either use two knobs spaced off the drawer centerline or move to a pull for the bigger boxes and keep the knob on the doors.
11) The Schaub 658 comes in Estate Dover and Polished Brass - what if I need a different finish family?
The Schaub 658 Avalon Bay square knob is offered in Estate Dover and Polished Brass. If the job needs a finish outside those, the Emtek Allerton and Art Deco cabinet knobs in the Schaub Collection and the Orca CK-19032 Whistler are separate knob programs with their own finish ranges, so you can match the rest of the cabinetry there instead of forcing the 658.
