Deltana CL308ILC Interconnected Lock Grade 2, Passage with Clarendon Lever

Both. The CL308ILC covers a 1-3/8 to 1-3/4 inch door thickness range, so it goes on older interior doors and on standard commercial 1-3/4 inch doors without a separate part number. Handing is universal, so you don't specify left or right when you order.

It ships 2-3/4 inch backset. A 2-3/8 inch backset is sold separately, so if the door is already bored on 2-3/8, order that latch rather than trying to make the standard one reach. Those are the two usual backsets on a bored lock, and measuring center of hole to door edge on the existing prep tells you which you need.

Four inches center to center between the two bores. That is the number that decides whether it drops onto an existing interconnected prep: if the door is bored on a different spacing, the escutcheon and the interconnect linkage won't line up and you're patching the door.

No. The CL308ILC is a passage function (hall and closet), so the lever always retracts the latch from both sides and there is no key or thumbturn locking. Use it on corridor, closet, and utility doors where you want a latched door that anyone can open. If the opening needs to lock, the Schlage CS210-B500 is a Grade 2 entrance-function interconnected lockset instead.

The Deltana CL308ILC uses a Schlage C keyway and is mechanical throughout. For openings that need credentials instead of cut keys in the same interconnected format, the Dormakaba Saffire LX-I is an electronic interconnect RFID lockset with Bluetooth, and the Dormakaba InSync RI5100G is a battery operated interconnected cylindrical latch and deadbolt lock with electronic RFID keys on a Gala lever. Both keep the interconnected latch-and-deadbolt arrangement while moving the credential from a key to a card or phone.

The Deltana CL308ILC Clarendon lever interconnected lock is a passage function, so the lever and deadbolt operate freely with no keyed control. When the opening needs to be secured, the Schlage CS210-B500 is a Grade 2 entrance single locking interconnected lockset - same interconnected lever-over-deadbolt arrangement and same Grade 2 rating, but an entrance function instead of passage.

The Deltana CL308ILC is an interconnected lock - a lever and a deadbolt tied together on a 4 inch center to center spacing, on a 2-3/4 inch backset, so retracting the lever releases both. A plain cylindrical lever lock such as the Schlage S270 classroom lock is a single bored function with no deadbolt tied to the lever, and it is keyed classroom rather than passage. If the door prep has two bores at 4 inch centers, the interconnected CL308ILC is the family that fits it; a single-bore S270 is not a drop-in for that prep.

It is a Grade 2 commercial lockset with a steel and zinc build, which is the normal duty level for multi-family corridor and unit-interior doors. Grade 2 is the mid tier of the ANSI/BHMA bored lock grades, above residential and below Grade 1 heavy institutional openings.

The latch has a 1/2 inch throw and is UL Listed. A 1/2 inch throw latch needs a strike whose lip and pocket are cut for a standard bored latch, so an existing ASA or T-strike from another bored lockset will normally take it, provided your latch prep is on the same backset you order.

It uses a Schlage C keyway, so it can be pinned into an existing Schlage C master key system by a locksmith. Worth noting on the passage version there is no cylinder in the lever function itself, so the keyway matters for the interconnect family and any keyed siblings you standardize alongside it.

An interconnected set like the CL308ILC ties the lever and the upper bore together in one trim on a 4 inch center to center spacing, so it installs as one unit and reads as one piece of hardware. Two separate bored functions give you free choice of backset and spacing but two preps and two trims to keep matched. If the door is already bored for an interconnect, stay with an interconnect.

Two Grade 2 heavy duty options: the Schlage S270 is a classroom function keyed cylindrical lever from the S200 Series, and the Schlage CS210-B500 is an entrance function single locking interconnected lockset in the CS210 Series. Pick the S270 for a single-bore classroom door and the CS210 if the door is prepped for an interconnect like the Deltana.

No. The Schlage Residential FC58 Plymouth is an outside handleset with 3 and 4 trim in the Custom FCT-Series, an entrance function residential handleset - a grip and thumbpiece on the exterior face, not a Grade 2 commercial interconnected lever. The Deltana CL308ILC is a commercial Grade 2 interconnected lock with a Clarendon lever on a 2-3/4 inch backset and 4 inch center to center spacing. The two use different door faces and different trim, so one does not cover the other's prep.

Both are non-locking trim, but they are not the same device. The Schlage Residential FC94 with Latitude lever and Collins trim is an inside dummy handleset - a surface-applied lever with no latch behind it, so it does not retract anything. The Deltana CL308ILC is a working passage interconnected lock: the Clarendon lever retracts a live latch with a 1/2 inch throw on a 2-3/4 inch backset. A dummy is for the inactive leaf of a pair; the CL308ILC is for a leaf that actually swings and latches.

For a facility standardizing on interconnected locksets, the mechanical options include the Deltana CL308ILC Clarendon lever, a Grade 2 universal handed unit in steel and zinc that covers 1-3/8 to 1-3/4 inch doors, and the Dormakaba J300 Series and QCI200 Series interconnected locksets. The Schlage CS210 Series covers the keyed entrance side of the same standard at Grade 2 heavy duty. Mixing within one interconnected family keeps the two-bore door prep consistent across the openings.

No. The Deltana CL308ILC Clarendon lever interconnected lock is universal handing, so one unit covers a left or right hand opening. By contrast the Dormakaba InSync RI5100G interconnected latch and deadbolt with the Gala lever is a right hand unit in satin chrome. On a retrofit where the handing of the existing door has not been confirmed, a universal unit like the CL308ILC removes that question from the order.

They answer different needs. The Deltana CL308ILC is a passage interconnected lock - always free from both sides, no key control - which suits closets, halls, and doors that only need latching. The Schlage S270 is a Grade 2 heavy duty classroom function cylindrical keyed lever lock in the S200 Series, so the outside lever can be locked by key while the inside always egresses. A classroom door that has to be secured from the corridor needs the S270 function; a hall or storage door that only needs to stay shut takes the CL308ILC.

Two: Brushed Chrome and Polished Brass. If you're matching existing hardware across a floor, Polished Brass reads with older brass trim and Brushed Chrome with satin chrome and stainless door furniture already on the openings.

Non-clutch. The lever is fixed to the spindle rather than spinning free, which on a passage set simply means the lever always drives the latch. Clutched levers exist mainly to protect keyed functions from force on a locked lever, so on a passage door the non-clutch build is the straightforward one.

The Deltana CL308ILC is fully mechanical - steel and zinc, Schlage C keyway, non-clutch, with no power source at the opening. The Dormakaba J300 Series and QCI200 Series are also mechanical interconnected locksets. The Dormakaba Saffire LX-I and the InSync RI5100G are the electronic side of the same category, the LX-I an RFID Bluetooth interconnect and the RI5100G battery operated with RFID keys, so those two bring a maintenance cycle the mechanical units do not.

The Deltana CL308ILC Clarendon lever interconnected lock comes in brushed chrome and polished brass. The Dormakaba InSync RI5100G interconnected latch and deadbolt is a satin chrome unit. For a building matching bright brass trim across its openings, the polished brass CL308ILC is the interconnected unit that carries that finish.
