Bravura Norfolk with Round Trim Dummy Knobset, Grade 2

A dummy knob is fixed trim. The Bravura Norfolk dummy knobset does not turn, has no latch and no cylinder, so it pulls the door closed and nothing more. Typical uses are the inactive leaf of a pair of French doors, a closet or pantry door held shut by a ball catch or roller catch, and any opening where you need matching hardware but no latching. If you need the door to stay shut on its own, order a passage or privacy knob instead.

No. A dummy has no latch, so it cannot keep a fire door in the closed and latched condition a rated opening requires. Use a latching lockset rated for the opening instead. The Falcon W101 Grade 2 knob lock with a 2-3/4 inch backset and the Falcon X101 Grade 1 passage knobset both carry a fire rating in our records.

The Bravura Norfolk with Round Trim is a dummy knobset in a single-finish configuration, US15 Satin Nickel or US10B Oil Rubbed Bronze. If the inactive leaf needs a knob on both faces, the Emtek Arts and Crafts Hammered Egg dummy and the Emtek Classic Brass Crystal Providence and Georgetown dummies are all sold as pairs. The BEST 6K-1DT is a single dummy trim, Grade 2 non-keyed, for one face only.

The Schlage A170 is the nearest match on function and grade: it is a single dummy trim, Grade 2 cylindrical non-keyed knob lock in the A Series, rated heavy duty, for doors 1-3/8 inch to 1-7/8 inch thick. The Bravura Norfolk with Round Trim is also a Grade 2 dummy knobset, but it is specified for residential use. If the opening is a commercial corridor or a facility standardizing on a commercial line, the A170 is the substitution to make.

A dummy has no latch, so it will not hold a door closed. For a hall or closet door that needs to latch but not lock, the Dexter C2000 Grade 2 passage ball knob or the Corbin Russwin CK4410 Grade 2 passage/closet knob both fit doors 1-3/8 inch to 1-3/4 inch. For a bed or bath door that needs to lock from inside, the Dexter C2000 privacy knob is the Grade 2 counterpart.

No. Dummy trim mounts to the face of the door, so there is no latch, no edge bore and no backset to set. That also means it does not care about door thickness the way a working lockset does. If your door already has a full 2-1/8 inch cross bore from a removed lockset, a dummy will cover the hole but you are usually better off filling and refinishing first.

Match the function to the door, not the trim style: a passage knob for a hall or closet, privacy for a bed or bath, entry where you need a key. If you are not staying within Bravura, Grade 2 knob options we carry include the Dexter C2000 passage and privacy knobs for 1-3/8 to 1-3/4 inch doors, and the Corbin Russwin CK4410 passage/closet knob over the same thickness range. Expect a visible difference in rose shape and knob profile from the Norfolk round trim.

Both are dummy-function cylindrical knobs. The Cal-Royal BA40 is from the Barrington BA Series and lists a door thickness range of 1-3/8 inch to 1-3/4 inch. The Bravura Norfolk is the Norfolk series in solid brass, Grade 2, and comes in US15 Satin Nickel and US10B Oil Rubbed Bronze. Choose on trim style and finish match, since the function is the same.

No. Those are exit device trims, not dummy knobsets. The Sargent 78-2875 is an outside knob only with B design from the 7800 Series, the Imperial USA ED-BKL580 is ED-500 Series knob trim in storeroom function, and the Sargent 28C-KNOB is exit device trim with knob and rose in classroom function for 1-3/4 inch doors. Each mounts to a panic device chassis. The Bravura Norfolk with Round Trim dummy knobset mounts directly to a bored door and is the correct part for a non-latching opening.

Two: US15 Satin Nickel and US10B Oil Rubbed Bronze. Both are standard finish codes, so if the rest of the doors in the unit are already US15 or US10B the Norfolk will sit alongside them without looking off.

The Bravura Norfolk dummy knobset is Grade 2 and residential. If you are outfitting a whole home and want a single line covering dummy plus keyed openings, Delaney Hardware offers Grade 3 entrance knobsets in the Belton, Galway and Olivia series along with the Brookhaven entry knob, and Callan offers Grade 2 entrance knobsets in the Edgewood and Roland series. Match the dummy trim shape to whichever entrance line you standardize on.
