Delaney Orlyn - Grade 2 Double Dummy Door Knob

A double dummy set is a pair of non-functioning knobs, one for each face of the door, with no latch and no lock. You push or pull the door instead of turning anything. That is what the Orlyn Grade 2 double dummy is: knob and rose trim for both sides, a dummy spindle, and mounting screws. Typical uses are one leaf of a pair of doors where the other leaf carries the working lock, closet or pantry doors held shut by a roller catch or magnet, and false doors. If you need the door to latch closed on its own, a dummy is the wrong part.

It's classified Residential, Grade 2. For single-family, condo, and apartment interior work it's in spec. For a commercial opening where a specifier calls out commercial-duty trim, look at commercial-classified dummy trim instead: the Schlage A170 single dummy is Grade 2 heavy duty, and the BEST 6K Series single dummy trim is Grade 2 medium duty. Note both of those are single dummy, so you'd order two if you want a knob on each face.

A dummy has no latch, so the Orlyn set gives you knobs, a dummy spindle, and screws and nothing that holds the door. Plan on a separate catch: a roller or friction catch, a ball catch in the door top, or a magnetic catch. On a pair of doors, the inactive leaf usually gets flush bolts or a surface bolt and the active leaf gets the working lockset. Budget that hardware on the same order, because the dummy alone will leave the door swinging.

No, and it's the most common mix-up on these. A passage knob turns and retracts a latch, so the door latches closed and the knob opens it. A dummy does neither; the Orlyn is fixed trim for push/pull only. If you want a non-locking knob that still latches, go to a passage function: the Dexter C2000 Grade 2 passage ball knob or the Corbin Russwin CK4410 Grade 2 passage/closet knob, both rated 1-3/8 to 1-3/4 inch doors, or the Pamex FTF Grade 3 Baron passage knob for the same thickness range.

For a Grade 2 dummy-function cylindrical knob, the Schlage A170 is the nearest peer - it is a Grade 2 cylindrical non-keyed knob lock in dummy function from the A Series, rated heavy duty and fitting doors 1-3/8 inch to 1-7/8 inch. The BEST 6K Series single dummy trim is also a Grade 2 non-keyed cylindrical dummy knob, listed as medium duty. The Orlyn is a Grade 2 dummy knob as well. The difference to settle first is sides: the Orlyn is sold as a double dummy, while the Schlage A170 and the BEST 6K-1DT are single dummy trim, which covers one face of the door only.

A dummy knob has no latch, so it will not hold a door closed. For a latching interior door in the same Grade 2 knob class, the Dexter C2000 passage ball knob is a Grade 2 non-keyed passage lock for doors 1-3/8 inch to 1-3/4 inch, and the Corbin Russwin CK4410 is a Grade 2 non-keyed passage/closet cylindrical knob over the same thickness range. Bravura Albany and Lynchburg are Grade 2 passage knobsets with round trim. For a bed or bath door that needs to lock from inside, the Dexter C2000 privacy ball knob is the Grade 2 privacy version.

They are different parts. The Orlyn double dummy has no latch and no lock and is meant for a push/pull interior door. A passage knob carries a latch that retracts when the knob turns: the Arrow MK01 and RK01 are Grade 2 non-keyed passage knobs for 1-3/8 inch to 1-3/4 inch doors, the Pamex FTF30 is a Grade 3 Baron passage knob over the same range, and the Schlage D10S is a Grade 1 heavy duty passage latch with an orbit knob. A passage knob needs a bored cross hole and latch prep in the edge of the door; a dummy knob does not.

Both. The Orlyn ships with combination screws that suit wood or metal door mounting, so you don't need to order a separate fastener pack for steel doors. On hollow metal you still need something solid behind the face at the screw locations, which is the normal consideration on any surface-mounted trim.

Projection is 2-3/8 inches off the door face, with a knob length of 2.5625 inches. That matters where the door swings into a tight reveal, sits next to a wall or casing, or where a second door leaf closes against it. Check the 2-3/8 inch projection against your clearance before committing, especially on closet doors in a narrow hall.

Within the Orlyn series, a dummy matched to working functions is the clean way to do it, and the Orlyn dummy is the non-keyed push/pull member of that family. If you need working functions in the same look from other lines ZenSupply carries, the Bravura Biloxi is a Grade 2 dummy knobset with round trim and Bravura also builds Albany and Lynchburg Grade 2 passage knobsets in round trim, so the dummy and the passage can come from one series. Emtek's Hammered Egg and Classic Brass Crystal Georgetown and Providence dummy pairs are also series-matched options on the decorative side.

Not for a bedroom or bath that needs to be secured. The Orlyn dummy has no lock and no latch, so there's no privacy function at all. For those openings use a privacy knob with a thumbturn: the Dexter C2000 Grade 2 privacy ball knob or the Pamex FTF Grade 3 Baron privacy knob, both listed for 1-3/8 to 1-3/4 inch doors, or the Deltana 6112 St. Thomas privacy knob for doors 1-3/8 to 2 inches. Dummies belong on closets, pantries, and the fixed leaf of a pair.

It depends on what's there. Because the Orlyn dummy is surface mounted with its own screws rather than through a bore, it does not fill a 2-1/8 inch cross bore the way a working lockset rose does, and a standard 2-1/8 inch hole is wider than typical knob rose trim will hide. If the door already has a bore and an edge latch prep and you want to keep it plain, a passage lockset is the better swap because it uses the existing prep. Use the dummy on an undrilled door, or where the bore will be plugged and patched.

Several knobs read as non-functioning at a glance but are not dummies. The Sargent 78-2875 is an outside knob only with B design, a trim piece for the 7800 Series exit device rather than a standalone dummy. The Imperial USA ED-BKL580 is knob trim in storeroom function from the ED-500 Series, also exit device trim. The Sure-Loc Arapaho and the Sure-Loc Bergen round knob 6-pack with adjustable backset are knobsets, not dummy trim. The Orlyn is a dummy knob with no latch and no lock, meant for a door that is pushed and pulled.

The Orlyn is a Grade 2 knob catalogued for residential use. For a commercial opening, the Schlage A170 single dummy trim is Grade 2 and rated heavy duty, and the BEST 6K Series single dummy trim is Grade 2 rated medium duty. Both are single-side trim rather than a double dummy set. If the corridor door needs to latch and hold, Falcon's X101 is a Grade 1 heavy duty passage knobset with a fire rating and a 1-3/8 inch to 2-1/4 inch door thickness range.

Among dummy-function knobs, the Cal-Royal BA40 Barrington BA Series dummy knob covers 1-3/8 inch to 1-3/4 inch, and the Schlage A170 Grade 2 dummy trim covers 1-3/8 inch to 1-7/8 inch, which is the widest dummy range in the comparable group. If the opening is thicker still and the door needs to latch, the Corbin Russwin CK4310 Grade 1 passage/closet knob and the Deltana 6171 round knob entry both cover 1-3/8 inch to 2 inch.

Matching across a unit usually means staying inside one series so the trim reads the same. Bravura offers Grade 2 dummy in the Biloxi round trim and Grade 2 passage in the Albany and Lynchburg round trims. Dexter's C2000 Series covers Grade 2 in passage, privacy, entry/office, and classroom ball knob functions across 1-3/8 inch to 1-3/4 inch doors. Corbin Russwin's CK4400 Series covers Grade 2 passage/closet. The Orlyn is a Grade 2 dummy in the Orlyn series, supplied in US15 Satin Nickel and US12P Tuscany Bronze.

The Orlyn is a Grade 2 dummy knob offered in US15 Satin Nickel and US12P Tuscany Bronze. For more ornamental styling in the same non-functioning role, Emtek's Classic Brass Crystal Georgetown and Providence knobs both come as dummy pairs, and the Arts and Crafts Hammered Egg knob comes as a dummy pair. Omnia's 434/0 is a traditional egg-shaped single dummy in solid brass, and the 442/00 is a traditional #44 single dummy with a 2-5/8 inch rose in solid brass. Emtek also lists porcelain knobs with a threaded rod, two knobs per set.
