Deltana CL501FLC Commercial Passage Standard Grade 1, Clarendon Lever with Cylinder

Yes. The CL501FLC is built for doors from 1-3/8 inch up to 2 inch thick, so it covers both older 1-3/8 interior doors and standard 1-3/4 commercial doors without any spacer kit. Above 2 inches it is out of range.

No handing to specify. The Clarendon CL501FLC is universal, so one part number works on a left or right hand door and you can stock a single SKU across a building.

It uses an ANSI strike, 4-7/8 x 1-1/4 inch with lip-to-center dimensioning, so it matches frames already prepped to standard ANSI 4-7/8 strike cutouts. If your frame has a small residential T-strike prep, the frame will need work.

The CL501FLC is a passage/hall/closet function lever that carries a single cylinder, so it is keyed on one side while the levers are free from both sides in normal use. If you want a plain non-keyed passage set with no cylinder at all, look at the Dexter C1000 passage lever or the Falcon K101, both Grade 1 non-keyed.

For a Grade 1 cylindrical passage lever, the closest peers are the Dexter C1000 Series passage lever, which is Grade 1 non-keyed with clutching levers and fits doors 1-3/8 inch to 1-3/4 inch, and the Falcon K101, a Grade 1 heavy duty passage cylindrical lock with non-handed levers, fire rated, covering 1-3/8 inch to 2-1/4 inch doors. The Deltana CL501FLC is Grade 1 with universal handing and a 1-3/8 inch to 2 inch door thickness range, so the Falcon K101 matches its door range most closely.

The Deltana CL501FLC Clarendon is a passage/hall/closet function, so the lever always retracts the latch. For keyed control, look at the Cal-Royal AG05 Grade 2 storeroom lever with deadlocking latchbolt, the Hager 2580 Grade 2 storeroom lever with Withnell lever, the Hager 2525 Grade 2 commercial entry lever, or the Dexter C1000 Grade 1 classroom lever, which is keyed with clutching levers on 1-3/8 inch to 1-3/4 inch doors.

The Deltana CL501FLC Clarendon covers 1-3/8 inch to 2 inch doors. Among peers that also reach down to 1-3/8 inch, the Hager 2510 Grade 2 passage lever covers 1-3/8 inch to 2 inch, the Falcon K101 Grade 1 passage covers 1-3/8 inch to 2-1/4 inch, and the Dexter C1000 Grade 1 passage covers 1-3/8 inch to 1-3/4 inch. The Arrow GL01 Grade 2 Sierra lever and Design Hardware X75 Grade 1 flat lever start at 1-3/4 inch, so they will not suit a thinner door.

It is a Grade 1 commercial cylindrical lockset, which is the highest ANSI/BHMA duty tier for bored locks, built from steel and zinc. Grade 1 is what specs call for on high traffic openings, and it is a step up from the Grade 2 passage levers like the Hager 2510 or Falcon B101.

Keying is selected at order time: keyed different if each door needs its own key, or keyed alike if a group of doors should share one. There is also a field to key to a specific code if you are matching an existing system in the building.

The CL501FLC itself is a passage function lockset, not a dummy. For the inactive leaf, ZenSupply carries Grade 1 dummy trim such as the BEST 9K Series 1DT single dummy, or the Accentra 455LN Augusta Grade 1 single dummy. Trim style will not match Clarendon exactly, so pick the closest rose profile.

Bored, not mortise. The CL501FLC is a tubular cylindrical lockset that installs in a standard cross-bore and edge bore, so there is no mortise pocket to rout. That is why the ANSI strike and the 2-3/4 backset matter more than any case dimension here.

The Clarendon tops out at 2 inch door thickness. For a thicker leaf, the Falcon K101 Grade 1 passage lever is listed for 1-3/8 to 2-1/4 inch doors and is also fire rated.

Yes. Grade 2 cylindrical passage levers include the Hager 2510 with Withnell lever, rated for 1-3/8 inch to 2 inch doors, the Falcon B101, a medium duty non-handed passage lever, and the Accentra 5301LN Augusta from the 5300 Series. The Deltana CL501FLC Clarendon is Grade 1, so the step to Grade 2 is a change in ANSI/BHMA cycle and strength classification.

The BEST 9K Series 1DT is single dummy trim - a Grade 1 non-keyed heavy duty lever with no latch mechanism, used as a pull on inactive leaves. The Accentra 455LN Augusta and the Callan Bentley are also dummy function. The Deltana CL501FLC Clarendon is a cylindrical passage lockset with a working latch and an ANSI 4-7/8 inch by 1-1/4 inch lip-to-center strike, so it is not interchangeable with dummy trim.

The Deltana CL501FLC Clarendon is passage function with no locking at the door. For privacy, the Hager 2540 Grade 2 privacy cylindrical lock with Withnell lever covers 1-3/8 inch to 2 inch doors, the Arrow MK02-TA is a non-keyed privacy cylindrical lock that is fire rated for 1-3/4 inch to 2 inch doors with a Tudor knob rather than a lever, and the Kwikset 300BRNL Breton is a Grade 3 privacy lever for 1-3/8 inch to 1-3/4 inch doors.

They solve different problems. The Deltana CL501FLC Clarendon is a mechanical passage lever with a cylinder and keying options. Keypad alternatives include the Lockey 2835 mechanical pushbutton keyless lever with passage function and ADA compliance for 1-3/16 inch to 2 inch doors, the Lockey 1150 heavy duty mechanical keypad lever with double combination passage function for 1-1/8 inch to 2 inch doors, and the Delaney LP250 Grade 2 electronic keypad leverlock. Those control access by code instead of a key.

Within Design Hardware, the J75 passage lever with flat lever is Grade 2 for 1-3/4 inch doors and the X75 is the Grade 1 flat-lever passage counterpart, also 1-3/4 inch. The Deltana CL501FLC Clarendon is a Grade 1 commercial passage lever with a wider 1-3/8 inch to 2 inch door thickness range and universal handing.

Three: Oil Rubbed Bronze, Brushed Chrome, and Polished Brass. Brushed Chrome is the usual match for existing satin commercial trim, while Oil Rubbed Bronze and Polished Brass suit hospitality and multi-family openings where the other hardware is decorative.

Yes, it uses fixed through bolts to secure the roses through the door, which is what keeps a lever from working loose on a high use opening.

The Deltana CL501FLC Clarendon is a commercial Grade 1 cylindrical lever in steel and zinc. For decorative interior trim, the Baldwin Estate 5103 passage lever with 5048 rose is a passage function set, and Bravura offers Grade 2 passage leversets in several trim styles, including the Atlanta and Orlando with round trim and the Tampa with square trim. Callan's Asheville is a Grade 3 passage leverset in satin nickel.
