Tell K2080 - Grade 2 Storeroom Knob Lockset

The outside knob on the K2080 stays rigid at all times and only a key retracts the latch from that side. The inside knob is always free, so anyone inside can get out without a key. The latchbolt is deadlocking. That is ANSI F86, the standard storeroom function for mechanical, electrical, and supply rooms where the door must never be left unlocked by accident.

Yes. The K2080 covers 1-3/8 inch through 2 inch doors, which takes in standard 1-3/4 inch commercial doors, older 1-3/8 inch interior doors, and thicker slabs up to 2 inches. Removable thru-bolts handle the adjustment.

Both. The K2080 is ordered with either a 2-3/4 inch backset (the standard commercial bore) or a 2-3/8 inch backset for residential prep. Measure from the door edge to the center of the existing bore before you pick, because the wrong backset will not line up with the hole in the door.

It ships with a 4-7/8 by 1-1/4 inch ASA strike, the standard commercial frame prep. If your frame is already cut for a full ASA lip strike, the K2080 drops straight in. If the frame has a small round-corner or T-strike from a residential lockset, you will need to enlarge the mortise in the jamb.

The K2080 uses a conventional cylinder with a Schlage C 6-pin keyway, so it works with C keyway blanks and existing C-keyed systems. Tell also supports other major keyways on this lock. At order time you choose keyed different, keyed alike for multiple openings, or no cylinder at all if your locksmith is supplying one.

No. The K2080 keeps the outside knob permanently locked, so entry is by key only. For an opening where the outside knob can be left unlocked during business hours, look at an entrance/office function instead, such as the Corbin Russwin CK4851 Grade 2 entrance/office cylindrical knob lock or the Dexter C2000 entry/office ball knob. For a door that never needs locking at all, a passage set like the Falcon W101 is the part.

Yes. The Sargent 8XG04 is a Grade 1 heavy duty storeroom/closet single cylinder knob lock with a 2-3/4 inch backset, from the 8X Line Series. The Tell K2080 is a Grade 2 storeroom lock, also with a 2-3/4 inch backset available, so the 8XG04 steps up a grade and duty level while keeping the same backset and storeroom function.

The Tell K2080 covers 1-3/8 to 2 inch doors. Among keyed knob locks, the Corbin Russwin CK4851 entrance/office cylindrical lock with a Global knob and conventional cylinder also lists a 1-3/8 to 2 inch door thickness range. Many other knob locks, including the Dexter C2000 keyed models, stop at 1-3/4 inch.

Yes. Keyed alike is a selectable option on the K2080, so a group of locks can be ordered to operate on one key, and there is a key code field if you need them cut to a code you already carry. Keyed different is the other choice when each door needs its own key.

Grade 2 suits light to moderate traffic storage and utility doors. For a high-abuse opening, a Grade 1 storeroom knob such as the Sargent 8XG04, which is heavy duty with a 2-3/4 inch backset, is the step up. If you want the same storeroom function in another Grade 2, the Sargent 6G04 storeroom/closet knob lock is a direct functional peer.

No handing to specify. Each knob has independent spring action, and the cylindrical chassis takes either swing, so one part covers left and right hand openings. Backset and finish are the only two choices that affect the physical fit.

It would lock students out rather than in. Storeroom keeps the outside knob rigid at all times, so there is no way to leave the door in an unlocked state. A classroom function, where a key sets the outside knob locked or unlocked, is the Dexter C2000 Grade 2 classroom ball knob lock.

Yes. Alongside keyed different and keyed alike, there is a less-cylinder choice on the keying option. Note that the lock is built around a conventional cylinder, not a small-format interchangeable core, so plan the replacement accordingly. If your standard is an IC system, a lock built for it, such as the Falcon X101 with interchangeable core, is the better fit.

For a non-keyed opening, look at passage knob locks. The Dexter C2000 Series passage ball knob is Grade 2, non-keyed, for 1-3/8 to 1-3/4 inch doors, and the Falcon W101 is a Grade 2 medium duty passage/closet knob lock with a 2-3/4 inch backset and a fire rating. The Tell K2080 is keyed with a deadlocking latchbolt and an always-fixed outside knob, which passage sets do not provide.

They are different functions. The Dexter C2000 entry/office ball knob is a Grade 2 keyed lock in the entrance/office function, where the outside knob can be left unlocked. The Tell K2080 is F86 storeroom: the outside knob is always fixed and always requires a key, and it cannot be left in an unlocked state. Use the entry/office lock only where you want an office that can be unlocked for the day.

The Dexter C2000 Series classroom cylindrical ball knob lock is Grade 2, keyed, for doors 1-3/8 to 1-3/4 inch thick. Classroom function lets a key outside lock and unlock the outside knob, whereas the Tell K2080 storeroom function keeps the outside knob permanently fixed with the key only retracting the latch.

No. The Schlage A170 is single dummy trim - a Grade 2 non-keyed knob with no latch mechanism, for doors 1-3/8 to 1-7/8 inch. It only provides a pull. The Tell K2080 is a keyed storeroom lockset with a deadlocking latchbolt and a conventional cylinder.

The Falcon X101 is a Grade 1 heavy duty cylindrical knobset with an interchangeable core, fire rated, for doors 1-3/8 to 2-1/4 inch, though it is a passage/closet function. The BEST 8K Series is a Grade 1 heavy duty entrance function knob lock. The Tell K2080 uses a conventional cylinder in a Schlage C 6-pin keyway and supports all major keyways.

Two: 630 satin stainless steel and 605 bright brass. Both are offered in either backset, so you can match a satin stainless building standard or existing bright brass trim without changing the bore.

Privacy function knobs handle those doors. The Dexter C2000 Series privacy ball knob is Grade 2 non-keyed for 1-3/8 to 1-3/4 inch doors, and the Cal-Royal BER20 is a Grade 3 privacy knob lock with brass trim for the same thickness range. Neither is keyed, unlike the keyed Tell K2080.

The Corbin Russwin CK4410 is a Grade 2 non-keyed passage/closet cylindrical lock with a Global knob for doors 1-3/8 to 1-3/4 inch thick - it always turns freely from both sides. The Tell K2080 is a keyed Grade 2 storeroom lock whose outside knob is always fixed, for a closet you need to keep secured.
