Dorma C580 Storeroom Keyed Lever Lockset

Storeroom function, ANSI/BHMA F86: the outside lever is always locked and retracts the latch only with a key, while the inside lever is always free for egress. The door relocks itself every time it closes, so nobody can leave a stock room, electrical closet, or mechanical room unsecured by accident. There is no way to hold it in an unlocked state, which is the point of the function.

The C580 uses a 2-3/4 inch backset and comes with a 15250 latch with a 1 inch square-corner faceplate, plus a 5001 ANSI strike measuring 1-1/4 by 4-7/8 inches. That is the standard ANSI 4-7/8 strike prep, so if the frame already has an ANSI cutout and the door bore is on a 2-3/4 backset, it goes straight in. If your existing openings are bored at 2-3/8 inches (typical on residential-grade doors), the C580 as supplied will not line up.

Yes, order the J cylinder option. The C580 is offered two ways: D for a conventional cylinder, and J for SFIC less core, which arrives without a core so your locksmith installs the small-format core that matches the building system. Pick J if the facility is already keyed on SFIC, D if you are keying it conventionally. Either way it is a single-cylinder keyed lock, keyed from the outside only.

No. The C580 tops out at 1-3/4 inches, so a 2 inch door is outside its adjustment range. For a thicker leaf, the Cal-Royal CAL30 Calypso Series covers 1-3/8 to 2 inches, though that one is a passage function rather than keyed storeroom. If the door needs to lock, verify the function before ordering, passage hardware has no cylinder at all.

The C580 adjusts for doors 1-3/8 inch to 1-3/4 inch thick. On a thicker leaf, the Cal-Royal Calypso series covers 1-3/8 inch to 2 inch - the CAL20 in privacy function and the CAL30 in passage, both Grade 1. The Lockey 1600 keyless knob lock spans 1-1/8 inch to 2 inch. None of those three is a keyed storeroom lock, so on a thick door that must stay locked to a key, confirm the door thickness against the C580 range before ordering.

The Marks USA 175RF is the nearest match. Both are Grade 2 cylindrical storeroom locksets on a 2-3/4 inch backset with an ANSI strike, and both are offered less core for small format interchangeable core cylinders - the C580 in its J - SFIC Less Core cylinder option. The C580 adds a conventional cylinder option (D) alongside the SFIC build, so if the building is keyed on a conventional keyway rather than an SFIC system, the C580 covers both paths under one model.

The C580 is certified to ANSI/BHMA Grade 2. Where a specification calls for Grade 1 in a keyed lever, the Marks USA 195RAB is an entry function clutched lever in the Grade 1 Survivor Series, supplied less core. Note the function change: the C580 is a storeroom lock, where the outside lever is always locked and the key retracts the latch, while the 195RAB is entrance/office function, which can be left unlocked for daytime traffic.

They share the same prep but not the same function. The Stanley QCL150 is a Grade 2 entry lever with a square 2-3/4 inch backset latch and a 4-7/8 inch by 1-1/4 inch ASA strike, which matches the C580 prep - a 2-3/4 inch backset with a 5001 ANSI 1-1/4 inch by 4-7/8 inch square corner strike. The difference is function: entrance allows the outside lever to be unlocked by the inside button or turn, while the C580 storeroom lever stays locked at all times and requires the key for every entry. The QCL150 also ships less cylinder.

It is a Grade 2 lock certified to ANSI/BHMA A156.2 Series 4000, which is the medium-duty commercial tier. Dormakaba lists the C500 Series for hotels, apartments, churches, municipal buildings, retail complexes, offices and warehouses. For a high-traffic main entrance or a school corridor where a facility standard calls for Grade 1, step up to something like the Marks USA 195RAB Survivor Series Grade 1 lever instead.

Handing on the C580 depends on which lever you pick, so it is a selection question rather than a chassis question. Choose the lever design (LC, LG or LR) that suits the opening and the lock chassis itself handles a storeroom function the same way either side. Confirm the lever style you are ordering matches the direction the door swings before you commit the order.

The Marks USA 175RF SFIC is the closest cross-brand equivalent: a Grade 2 storeroom clutched lever, small format IC less core, 2-3/4 inch backset, with an ANSI strike. It matches the C580 J option almost point for point on function, grade and backset. The clutched lever on the Marks is the practical difference, the outside lever spins freely when locked rather than resisting force.

The C580 is a mechanical key-in-lever lock, no batteries, no programming, no audit trail. That is what you want on a closet or storeroom where a small number of people carry keys and the lock has to work in twenty years without service. If you need to change access without rekeying, or want to know who opened the door, go electronic instead: the Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone keypad cylindrical lock with 100 user codes and IC/SFIC compatibility, and it fits doors 1-5/8 to 1-7/8 inches, a different range from the C580, so check the door before switching types.

Yes, that is how the C500 Series is built. Ten functions share the same chassis, lever designs and finishes, so the C580 storeroom on the supply closet can sit alongside other C500 functions on offices and restrooms with the trim matching across every opening. Order them all on the same cylinder option, D conventional or J SFIC less core, and the whole floor keys as one system.

The C580 is a keyed single cylinder storeroom lock. For openings on the same doors that only need latching without a key, the Orca Hardware OCL210 is a Grade 2 passage cylindrical lockset and the OCL240 is a Grade 2 privacy lockset for restrooms and bed/bath doors. Both are medium duty. Where the door needs a knob rather than a lever, the C580 is lever only - its handle type is lever across every build.

An electronic cylindrical lock changes both the credential and the door thickness math. The Alarm Lock Trilogy T2 DL2700 is a Grade 1 standalone electronic cylindrical lock with a digital keypad, 100 user codes and IC/SFIC compatibility, but it fits doors 1-5/8 inch to 1-7/8 inch - a range that does not reach the 1-3/8 inch minimum the C580 covers. The BEST 9KZ EZ Series keypad lock offers key override so a mechanical key still works the opening. The C580 is mechanical single cylinder throughout, so keying is the only credential.

Storeroom and classroom are different security models. The C580 is a storeroom lock: the outside lever is permanently locked and a key retracts the latch, with no way to leave it unlocked. The TownSteel XCE-2000 is a Grade 1 heavy duty electronic classroom lockset with a keypad for doors 1-3/4 inch to 2 inch, and the XCE-9000 adds classroom intruder function for lockdown from inside the room. Schools specifying lockdown capability need the classroom function; storage rooms, mechanical rooms and supply closets are where the C580 storeroom function belongs.

The C580 is a mechanical key-operated storeroom lever and does not accept a wired signal. The SDC Electra 7200 Series is a solenoid controlled cylindrical lock running dual voltage 12/24VDC for doors 1-3/4 inch to 2 inch, which is the fit for an opening released from a card reader or panel. The Schlage NDEB is a Grade 1 heavy duty ENGAGE Series cylindrical lock with a 2.4 GHz Bluetooth Low Energy reader for doors 1-5/8 inch to 2 inch, for credential access without pulling wire to the door. Both start above the 1-3/8 inch minimum the C580 handles, so verify leaf thickness first.

Six finishes across the C580: 605 bright brass, 606 satin brass, 613 oil rubbed bronze, 619 satin nickel, 625 bright chrome and 626 satin chrome. 626 satin chrome is the usual commercial default and the one most likely to match existing lever hardware in an office or apartment building; 613 oil rubbed bronze is the choice where the rest of the openings are dark. All six are available with either lever family and with either the conventional or SFIC cylinder.

The C580 is a commercial Grade 2 cylindrical lockset certified to ANSI/BHMA A156.2 Series 4000, recommended for hotels, apartments, churches, municipal buildings, retail complexes, offices and warehouses. The Kwikset 912TNL SmartCode is a keyed one side electronic Tustin lever with Z-Wave for doors 1-3/8 inch to 2 inch. On a multi-family unit entry where the owner wants code access and integration, the 912TNL is the different tool; for back-of-house and service doors keyed into a building master, the C580 storeroom lever is the commercial-rated part.

The C580 is a keyed storeroom lockset and does not have a dummy build. The Orca Hardware OCL2170 is a Grade 2 half dummy lever, medium duty, for the inactive leaf of a pair or a closet face that needs a pull only. It is a different manufacturer, so the lever profile will not match the C580 LC, LG or LR designs - confirm the lever shape and finish if visual consistency across the doors matters.
