Dexter C2000 Series - Grade 2 Storeroom Cylindrical Ball Knob Lock, Non-Clutching, Keyed

Both. The C2000 cylindrical knob lock covers a 1-3/8 inch to 1-3/4 inch door range as standard, which is the usual commercial 1-3/4 and the older interior 1-3/8. No spacer kit or thickness suffix to specify inside that range.

Standard is the C2000-SD-234 deadlatch at 2-3/4 inch backset with a 1 inch diameter latch. If your doors are bored at 2-3/8, the C2000-DL 2-3/8 deadlatch is selectable at order as the backset option, so you can match either prep without changing lock chassis.

Yes. Storeroom function means the outside knob is always fixed and takes a key every time; the inside knob always retracts the latch for free egress. There is no button or turn to leave it unlocked, which is why it goes on mechanical rooms, electrical closets, and janitor rooms where you don't want anyone leaving the door on passage. It's an ANSI/BHMA F86 function, single cylinder.

The C2000 ships with the C2000-ACLS ANSI 1-1/4 x 4-7/8 inch curved lip strike, which is the standard commercial frame prep, so on an ANSI-prepped hollow metal frame it drops straight in. The latch faceplate is 1 x 2-1/4 inch. If your frame carries the smaller T-strike cutout rather than a full ANSI 4-7/8 lip strike, the frame will need work.

Yes, order the SFIC Prep Less Core version. It comes prepped to accept a 6-pin or 7-pin small format interchangeable core, and you supply the core from your own system, so the lock joins your existing keying without rekeying anything. The alternative is KDC, a conventional 6-pin Schlage C cylinder keyed different, which suits a one-off door rather than a keyed system.

The C2000 cylindrical lock is UL listed 3 hour, so it can go on a rated opening up to that rating. It's a Grade 2 commercial lock, which is the level normally specified for institutional interior and back-of-house doors.

A storeroom lock like the Dexter C2000 ball knob keeps the outside knob locked at all times and only a key retracts it - there is no button or turn to leave the door unsecured. An entrance/office lock such as the Corbin Russwin CK4851, a single cylinder global knob lock with a conventional cylinder, or the Cal-Royal BER00, a Grade 3 entrance/office knob lock with a Kwikset keyway for doors 1-3/8 to 1-3/4 inch thick, lets an occupant set the outside knob unlocked so the room can be left open through the day. Choose storeroom where staff must never be able to leave the room unsecured, and entrance/office where an occupant controls the door.

The Sargent 6G04 is the nearest match. It is a Grade 2 storeroom/closet knob lock with a single cylinder, which is the same grade, same storeroom function and same single-cylinder keying arrangement as the Dexter C2000 storeroom ball knob. Both give you an outside knob that stays locked and is retracted by key while the inside knob always allows free egress, so either one suits a mechanical, electrical or supply room on a commercial opening. The Sargent 6G04 is rated standard duty.

Step up to the Sargent 8XG04. It is a Grade 1 storeroom/closet single cylinder knob lock with a 2-3/4 inch backset, rated heavy duty, where the Dexter C2000 storeroom ball knob is Grade 2. The function and keying are the same on both - storeroom, single cylinder - and the 8XG04 shares the 2-3/4 inch backset the Dexter C2000 carries as standard, so the door prep does not change when you move up the grade. Specify the 8XG04 where a stairwell, corridor or dock door sees continuous cycles or where the spec calls out ANSI Grade 1.

No handing to call out. The C2000 knob lock is non-handed, so one part number works on left or right hand doors and inswing or outswing. The beveled deadlatch reverses in the field.

Three finishes: 605 bright brass, 613 oil-rubbed bronze, and 630 satin stainless steel. All three are available with either the conventional Schlage C cylinder or the SFIC prep, so a property manager can standardize one finish across a facility and still mix keyed-different doors with interchangeable-core doors.

Step up to the Sargent 8XG04, a Grade 1 heavy duty storeroom/closet knob lock with a 2-3/4 inch backset and single cylinder. Same function and same backset as the Dexter C2000, built to the higher grade for high-traffic or abuse-prone openings. If Grade 2 is fine for the traffic, the Sargent 6G04 is a standard duty Grade 2 storeroom knob lock and sits alongside the C2000.

The KDC cylinder option is a 6-pin conventional cylinder in the Schlage C keyway, keyed different from the factory. Same keyway as your existing Schlage C hardware, so a locksmith can rekey it into an existing C-keyway system; as shipped each lock has its own key. If you run interchangeable core instead, take the SFIC prep and drop in your own core.

The Dexter C2000 ball knob covers 1-3/8 to 1-3/4 inch doors. For a thicker leaf, the Falcon X101 is a Grade 1 heavy duty cylindrical passage knobset with an interchangeable core rated for 1-3/8 to 2-1/4 inch doors, and the Corbin Russwin CK4310 is a Grade 1 passage/closet knob for 1-3/8 to 2 inch doors. Both of those are passage function, so if the thick door also has to be keyed, measure the leaf before committing and confirm the storeroom function is available in the range you need.

For an opening that only needs a latch and no key, look at the Corbin Russwin CK4410 passage/closet cylindrical lock, a Grade 2 non-keyed global knob for doors 1-3/8 to 1-3/4 inch thick, or the Falcon W101, a Grade 2 medium duty passage/closet knob lock with a 2-3/4 inch backset and a fire rating. Both share Grade 2 with the Dexter C2000 storeroom ball knob and the Falcon W101 shares its 2-3/4 inch backset, so the bore and latch prep carry over; what you give up is the key. Use passage on closets, corridors and utility doors that are never secured, and keep the storeroom function where the door must stay locked at all times.

No. The Schlage A170 is single dummy trim - a Grade 2 non-keyed knob for doors 1-3/8 to 1-7/8 inch thick with no latch and no cylinder. It is a pull mounted to the face of the door, so it will not secure anything. The Dexter C2000 storeroom ball knob is a keyed cylindrical lock with a single cylinder and a deadlatch. Order dummy trim only for the inactive leaf of a pair or a door held by a magnet or ball catch. The BEST 6K single dummy trim and the Bravura Biloxi dummy knobset are in the same non-latching category.

They answer different jobs. The Kwikset 400P-CP Polo keyed entry knob is Grade 3 for doors 1-3/8 to 1-3/4 inch, and the Master Lock BC series biscuit knob is a Grade 3 keyed entry lock; both are entrance function, meaning the outside knob can be left unlocked. The Dexter C2000 ball knob is Grade 2, commercial, storeroom function, and keyed with a single cylinder so the outside knob is always locked. On an apartment unit door or a house, the Grade 3 entry knobs do the job; on a commercial supply or equipment room that must stay secured, specify the Grade 2 storeroom lock.

The Dexter C2000 ball knob is offered in an SFIC prep less core version alongside the conventional 6-pin Schlage C cylinder, so you can drop your own core in at the site. The Falcon X101 is a Grade 1 heavy duty cylindrical knobset supplied with an interchangeable core, though it is passage function and carries no cylinder to key. If you are standardizing one core system across storerooms, the SFIC prep version of the C2000 keeps the storeroom function and lets the locksmith core it on delivery.

The Lockey 3830 is a mechanical keyless combination knob lock with an auto-locking passage function, for doors 1 3/16 to 2 inch thick. It uses a pushbutton code rather than a cylinder, so a crew that rotates does not need keys cut and a code change replaces a rekey. The Dexter C2000 ball knob works the other way - a single cylinder keyed to Schlage C, or an SFIC prep so you can core it into an existing master key system. Pick the combination lock for a door with changing users and no keying system; keep the cylinder lock where the storeroom must sit under the building master.

To keep one look and one grade across a floor, the Arrow RK01 is a Grade 2 ball knob passage cylindrical lock for 1-3/8 to 1-3/4 inch doors and the Arrow MK01 is a Grade 2 passage knob lock for the same door range. Both are non-keyed. The Dexter C2000 ball knob is Grade 2 across the same 1-3/8 to 1-3/4 inch door range, so a corridor with a mix of secured storerooms and open closets can run the keyed storeroom lock on the ones that lock and the passage knobs on the ones that do not, with the door prep and the grade holding steady throughout.

Ball knob is what the C2000 storeroom set uses. Knobs require grasping and twisting, so on doors along an accessible route most facilities specify a lever instead. Knob is generally acceptable on storage, mechanical, and utility rooms that are not part of an accessible route, which is exactly where a storeroom function lands. Check your local code for the specific opening.

A storeroom lock is the wrong function for a room someone occupies - it has no inside thumbturn. Use a privacy set instead: the Cal-Royal BER20 is a Grade 3 privacy knob lock with brass trim for doors 1-3/8 to 1-3/4 inch, and the Pamex FTF Baron is a Grade 3 privacy knob lockset for the same door range. Both lock from the inside and release with an emergency tool from the corridor side. Keep the Dexter C2000 storeroom knob on the doors that must stay locked to everyone without a key.

They serve different doors. The Deltana 6901 Portland knob is an entry set for 1-3/8 to 1-3/4 inch doors and the Deltana 6171 Round knob is an entry set for 1-3/8 to 2 inch doors; the Baldwin Estate 5011 Colonial is a passage knob with a 5058 rose. These are finished residential and estate trim. The Dexter C2000 ball knob is a commercial Grade 2 storeroom lock carrying an ANSI/BHMA F86 function designation. On an office suite entry or a residence the decorative sets fit the look; where a specification calls out an ANSI function and a commercial grade, the C2000 is the one that answers it.
