Delaney Derby - Grade 3 Privacy Knobset

The Derby is a non-keyed privacy set, the bed and bath function. It locks from inside the room only, so it suits bathrooms, bedrooms, or any room that needs to be secured from within. There is no cylinder and no key to manage. If you need a keyed exterior or office door, a privacy set is the wrong function.

Everything for a complete install is in the carton: knob and rose plate for both sides of the door, the latch mechanism, a standard spindle, a full-lip strike plate, and mounting screws. You do not order the latch or strike separately. Nothing extra is needed unless the door is not already bored.

Grade 3 is the residential duty level, and the Derby is catalogued for residential use. For apartment bedrooms and bathroom doors that is the normal choice. For high-traffic commercial interiors, step up in grade: Dexter's C2000 privacy ball knob is Grade 2, and the Corbin Russwin CK4300 series runs Grade 1.

The Delaney Derby privacy knobset is a Grade 3 cylindrical knob lock with a Privacy/Bed/Bath function. Two Grade 3 privacy knob locks match it on both counts: the Cal-Royal BER20, a Grade 3 privacy knob lock with brass trim rated for doors 1-3/8 inch to 1-3/4 inch thick, and the Pamex FTF Baron knob lockset in privacy function, also Grade 3 with the same 1-3/8 inch to 1-3/4 inch door thickness range. Both turn the interior button and release the same way a bed or bath door needs.

The Delaney Derby privacy knobset is a Grade 3 knob listed for residential use. For a higher-traffic bath or bedroom door, the Dexter C2000 Series privacy cylindrical ball knob is a Grade 2 non-keyed privacy lock for doors 1-3/8 inch to 1-3/4 inch thick. Deltana also offers the 6112 St. Thomas knob in privacy function, which covers a wider 1-3/8 inch to 2 inch door thickness range.

Dummy knobs are the common mix-up. The Bravura Biloxi with round trim is a Grade 2 dummy knobset, the Schlage A170 is a Grade 2 single dummy trim, and the Cal-Royal BA40 is a dummy knob for 1-3/8 inch to 1-3/4 inch doors. All of these are surface trim with no latch and no locking button, so none of them substitutes for the Delaney Derby, which is a privacy knobset supplied with a latch mechanism, spindle and full-lip strike plate.

Both. The Derby ships with combination screws that suit wood or metal door mounting, so the same set covers a wood interior door and a hollow metal one.

Projection is 2-3/8 inches from the door face, with a 2.5625 inch length figure on the trim. That matters where a door swings back against a wall or beside a narrow vanity. For comparison, the Omnia 434/PA knob latchset projects 3 inches.

Two: US15 Satin Nickel and US12P Tuscany Bronze. Satin nickel is the easier one to match across a building since most builder-grade interior hardware is specified in it; Tuscany Bronze is the darker option for bronze or oil-rubbed schemes.

The Derby is the privacy function only, so match the look within the Derby line for other openings rather than mixing series. If you are standardizing a whole floor and want one family across functions, Callan and Pamex both cover several: Callan's Canova and Santo are Grade 3 entrance knobsets, and Pamex's Baron FTF line runs privacy, passage, and entrance/office all at Grade 3.

The Derby ships a full-lip strike plate, which is the standard flat plate for wood jambs and for hollow metal frames prepped for a full-lip strike. If your frame has a round-corner or radius strike prep, the flat full-lip plate will not drop straight into it. Kwikset's Polo sets, for example, ship a round corner strike instead.

The Delaney Derby privacy knobset is non-keyed. For a keyed exterior or office door, Grade 3 keyed knob options include the Cal-Royal BER00 entrance/office knob lock with a Kwikset keyway for 1-3/8 inch to 1-3/4 inch doors, the Pamex FTF Baron knob lockset in entrance/office function, and the Kwikset 400P-CP Polo keyed entry knob, a Grade 3 lock for 1-3/8 inch to 1-3/4 inch doors supplied with an adjustable round corner latch and strike.

The Pamex FTF Baron family is offered in privacy, passage and entrance/office functions, all Grade 3 for doors 1-3/8 inch to 1-3/4 inch, so one trim style covers all three door types. Cal-Royal's Grade 3 knobs cover the same spread with the BER20 privacy and BER00 entrance/office. The Delaney Derby covers the privacy function in the Derby series and is offered in US15 Satin Nickel and US12P Tuscany Bronze.

The Deltana 6112 St. Thomas knob in privacy function is listed for doors 1-3/8 inch to 2 inch thick, which is broader than the 1-3/8 inch to 1-3/4 inch range carried by the Cal-Royal BER20 and the Pamex FTF Baron privacy knob. The Delaney Derby privacy knobset ships with combination screws that suit both wood and metal door mounting and a standard spindle.

No. It is a cylindrical bored lockset with a knob on each side and a spindle through the door, so it works on a left or right hand door without any handing selection. Only the latch face orientation follows the swing, and that sets itself when you install.

Both serve a bed or bath door. The Baldwin Estate 5077 Bethpage privacy knob with R027 rose and the Baldwin Estate 5000 Baltimore knob with 5148 rose, which is preconfigured with a 2-3/8 inch backset and full lip strike, are privacy-function decorative knobs. The Delaney Derby is a Grade 3 cylindrical privacy knobset offered in US15 Satin Nickel and US12P Tuscany Bronze, supplied complete with latch, standard spindle, full-lip strike plate and mounting screws.
