Emtek Porcelain Knobsets, Ice White Knob, Passage Set

Yes. The Emtek Porcelain knobset drops into standard door prep: a 2-1/8 inch cross bore, with the standard latch set for a 2-3/8 inch backset. If your existing prep is bored at 2-3/4 inches from the edge, specify the 2-3/4 inch backset when you order. One exception on the rosette side: the STRETTO rosette needs a 1-1/4 inch diameter bore and a 2-hole door prep for thumbturn privacy, so it is not a straight drop-in to a single 2-1/8 inch bore.

Two thickness options cover the range. Standard covers 1-1/4 to 1-3/4 inch doors, which handles typical 1-3/8 inch interior and 1-3/4 inch doors. For anything heavier, order the extended option, which covers 1-3/4 to 2-1/4 inches. That is a real difference from most residential knobsets, which stop at 1-3/4.

No. Passage means the knob latches the door but never locks, so it is for halls, closets, and doors that only need to stay shut. For a bedroom or bath you want privacy function with a push-button or thumbturn. ZenSupply carries privacy knobs like the Baldwin Estate 5077 Bethpage and the Deltana 6112 St. Thomas, both privacy/bed/bath function.

In most cases yes. Standard residential prep is a 2-1/8 inch cross bore with a 2-3/8 or 2-3/4 inch backset, which is exactly what the Emtek is built for, and the set includes its own latch and strike so you swap the whole thing. Measure the backset from the door edge to the center of the bore before you order and pick that value. Check the latch faceplate corner as well, round or square, so it drops into the existing mortise without recutting.

The Emtek Porcelain Ice White passage set is a residential brass knobset with a tubular latch, so a commercial opening is better served by a rated cylindrical passage knob. The Schlage D10S is a Grade 1 heavy duty non-keyed passage knob lock with an Orbit knob, and the Corbin Russwin CK4310 is a Grade 1 passage/closet cylindrical lock with a Global knob covering doors 1-3/8 inch to 2 inch thick. Both hold the same passage function - latch retracts from either side with no locking - while carrying an ANSI grade the porcelain set does not target.

The Emtek Porcelain Ice White set is non-keyed, so a door needing a key takes an entrance or storeroom function knob instead. The Corbin Russwin CK4851 is an entrance/office cylindrical lock with a Global knob and conventional cylinder for doors 1-3/8 inch to 2 inch, the Sargent 6G04 is a Grade 2 storeroom/closet knob lock with a single cylinder, and the Cal-Royal BER00 is a Grade 3 entrance/office knob lock built around the Kwikset keyway for doors 1-3/8 inch to 1-3/4 inch. Emtek builds the porcelain knob in keyed versions as well if the decorative look has to carry through the opening.

For a decorative interior passage knob in the same residential category, the Baldwin Estate 5000 Baltimore knob with 5048 rose is a passage lock supplied with a 2-3/8 inch backset and full lip strike, and the Baldwin Estate 5011 Colonial is a passage/hall/closet knob with the 5058 rose. The Omnia 434/PA is a traditional egg-shaped knob latchset in solid brass with a 3 inch projection. The Emtek porcelain set differs in the knob material itself - a porcelain knob on a brass base - and in offering an adjustable 2-3/8 inch or 2-3/4 inch backset with a choice of Lancaster, Porcelain, Ribbon and Reed, or Rope rosette.

A passage set has no locking mechanism, so a bath or bedroom door needs a privacy function instead. The Baldwin Estate 5000 Baltimore knob with 5148 rose is a privacy lock with a 2-3/8 inch backset and full lip strike, the Deltana 6112 St. Thomas knob is a privacy set for doors 1-3/8 inch to 2 inch thick, and the Pamex FTF Baron privacy knob lockset is a Grade 3 unit for doors 1-3/8 inch to 1-3/4 inch. Emtek also builds the porcelain knob in a privacy version; note that a STRETTO rosette needs a 1-1/4 inch bore and 2-hole prep for thumbturn privacy.

The Emtek Porcelain Ice White passage set fits doors 1-3/8 inch to 2-1/4 inch thick with a 2-1/8 inch bore standard prep, ordered with the extended door thickness option for 1-3/4 inch to 2-1/4 inch. Among cylindrical peers, the Corbin Russwin CK4310 Grade 1 passage lock covers 1-3/8 inch to 2 inch and the Falcon X101 Grade 1 passage knobset covers 1-3/8 inch to 2-1/4 inch, while the Corbin Russwin CK4410 Grade 2 and the Dexter C2000 passage knob stop at 1-3/4 inch.

When a drawing calls out an ANSI/BHMA grade on a passage knob, the graded passage units include the Schlage D10S at Grade 1 heavy duty, the Corbin Russwin CK4310 at Grade 1, the Falcon X101 at Grade 1 heavy duty, and at Grade 2 the Corbin Russwin CK4410, the Dexter C2000 passage ball knob, the Arrow MK01 and RK01, and the Falcon W101 medium duty. The Emtek Porcelain Ice White passage set is a residential decorative knobset in brass and suits openings written without a grade callout.

It ships as a complete set: both knobs, the rosettes, the latch, and the strike plate. Nothing else to buy to hang it on a door that is already bored. The latch faceplate comes round or square corner, so match whatever is already mortised into your door edge.

The 28 degree rotation latch reduces how far the knob has to turn to retract the bolt, which suits anyone who wants a shorter throw of the hand. It is an extra-cost option, so if you have no reason to want the shorter rotation, take the standard latch.

Four rosettes: Lancaster, Porcelain, Ribbon and Reed, and Rope. Seven finishes on the brass hardware: French Antique (US7), Oil Rubbed Bronze (US10B), Pewter (US15A), Polished Brass Lifetime (US3), Polished Chrome (US26), Satin Nickel (US15), and Unlacquered Brass (US3NL). The knob itself stays Ice White porcelain; the finish applies to the brass. Any brass rosette in the line can be ordered with it, so you can match the rosette to trim you already have elsewhere in the house.

No. It is non-keyed with no cylinder and no keyway, so there is nothing to key or to add to a master system. If you need a keyed opening in a similar residential look, the Baldwin Estate 5000 Baltimore is offered in a keyed configuration, and the Deltana 6901 Portland is an entry knob for 1-3/8 to 1-3/4 inch doors.

Yes, that is how the Porcelain collection is built. The Ice White knob runs across functions, so you can put passage on halls and closets and privacy on bedrooms and baths while the knob, rosette, and finish stay identical. Keep the same rosette and the same finish code across every door and the openings read as one set.

For a straightforward interior passage knob, the Kwikset 200P Polo passage knob ships with a 6AL latch and RCS round corner strike, and the 200P-CP version comes with a round corner adjustable latch and round corner strike. The Dexter C2000 is a Grade 2 passage cylindrical ball knob lock, non-clutching and non-keyed, for doors 1-3/8 inch to 1-3/4 inch, and the Pamex FTF Baron is a Grade 3 passage knob lockset for the same thickness range. The Emtek porcelain set differs in that the knob is porcelain on a brass base with a selectable rosette and comes in seven finishes including Oil Rubbed Bronze US10B and Unlacquered Brass US3NL.

No, despite both being described as passage. The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function for doors 1 3/16 inch to 2 inch, meaning the outside knob is controlled by a code. The Emtek Porcelain Ice White set is non-keyed passage with no locking at all - the knob turns freely from both sides. If access control on the door matters, the Lockey is the different product, not the alternate finish.

No. The Sargent 28C-KNOB is exit device trim with a knob and rose in entrance function for 1-3/4 inch doors, meaning it mounts to a 28 Series exit device rather than working as a standalone lock, and the Sargent 78-2875 is an outside knob only with B design for the 7800 Series. The Emtek Porcelain Ice White set is a complete bored knobset with its own latch and strike plate for a 2-1/8 inch cross bore.

For a standardized residential run, the Schlage Residential F500 Plymouth with Georgian knob is a combo pack with adjustable backsets and dual strikes for doors 1-3/8 inch to 1-3/4 inch, and the Bravura Albany and Lynchburg round trim passage knobsets are Grade 2 passage units. The Emtek Porcelain Ice White passage set is bought per opening instead, with backset selected as 2-3/8 inch or 2-3/4 inch and the standard or 28 degree rotation latch chosen at order time, which is what lets a mixed set of openings all carry the same porcelain knob.
