Deltana CL300ILC Interconnected Lock Grade 2, Entry with Clarendon Lever

Both. The CL300ILC covers a 1-3/8 to 1-3/4 inch door thickness range, so it works on older interior slabs and standard commercial doors without a separate part number. The lever is universal handed, so one lock covers left and right hand openings.

It ships 2-3/4 inch backset. Deltana sells the 2-3/8 inch backset separately, so if your existing cross bore is 2-3/8 inches from the door edge you order that piece rather than the standard lock. Those are the two usual residential and commercial backsets, so measure edge of door to center of the knob hole before you order.

On the CL300ILC the deadbolt and the latch are tied together, so one turn of the inside lever retracts both at once. That single motion egress is why apartment and multi-family entry doors use interconnected sets instead of a lever plus a standalone deadbolt, where a resident has to operate two devices to get out. Outside, it is keyed entry with a single cylinder.

It uses the Schlage C keyway, so a locksmith can key it into an existing Schlage C system and run it keyed alike with the rest of the building. That is the single most useful thing about it for a property manager standardizing a fleet of unit doors: no new key section to carry.

The Schlage CS210-B500 is the nearest straight equivalent. Both are Grade 2 interconnected locksets with an entrance function, so a single turn of the inside lever retracts latch and deadbolt together for egress. The CL300ILC uses a Clarendon lever on a steel and zinc body with a Schlage C keyway, single cylinder keyed. The Schlage CS210-B500 is rated heavy duty in the CS210 series. Confirm backset and door thickness against the opening before swapping either one in.

An entrance function like the CL300ILC keys from the outside and is meant for apartment and unit entry doors, not for a room that has to be secured from the corridor side on a classroom cycle. The Schlage S270 is a Grade 2 heavy duty cylindrical keyed lever lock in the S200 series with a classroom function. Note that the S270 is a cylindrical lever lock rather than an interconnected latch and deadbolt unit, so a classroom opening that also needs a deadbolt will need that specified separately.

The CL300ILC is a mechanical lock, keyed single cylinder on a Schlage C keyway, so access control means cutting and tracking keys. For an interconnected opening on electronic credentials, the Dormakaba Saffire LX-I is an electronic interconnected RFID lockset with Bluetooth and a 3-hour fire rating, and the Dormakaba InSync RI5100G-26D is a battery operated interconnected cylindrical latch and deadbolt lock with electronic RFID keys, supplied with a Gala lever in satin chrome and right handed. The CL300ILC is universal handed, so a mechanical rekey program and an electronic one differ in handing planning as well as credentials.

No. The Schlage Plymouth FC58 PLY is a residential outside handleset with 3 and 4 trim, and the FC94 LAT COL is a residential inside dummy handleset with a Latitude lever and Collins trim, meaning the dummy half does not operate a latch at all. Neither is an interconnected lockset. The Deltana CL300ILC is a commercial Grade 2 tubular interconnected lock where the inside lever retracts the latch and deadbolt in one motion, which is what an egress-code apartment entry door is specified for.

The latch is UL Listed with a 1/2 inch throw. A 1/2 inch throw is the standard cylindrical latch projection, so it engages a normal ANSI strike prep in the frame. The lock itself is Grade 2, built for commercial duty.

No. The CL300ILC is an entry function interconnected set, made for a unit or dwelling door where one lever motion pulls both bolts. A classroom needs classroom function, where the outside lever is locked and unlocked by key and there is no inside locking. The Schlage S270 is the Grade 2 cylindrical classroom lever for that opening.

Within mechanical interconnected locksets, the Dormakaba J300 series and the Dormakaba QCI200 series are both interconnected locksets covering the same single-motion egress opening the CL300ILC covers. The Deltana CL300ILC is specified Grade 2, universal handing, 4 inch center to center between lever and deadbolt, with a UL listed latch at 1/2 inch throw and a 2-3/4 inch backset. On a retrofit the center to center dimension and backset are what decide whether the existing bores are reusable, so match those before choosing between families.

For a rated corridor or stair opening, the Dormakaba Saffire LX-I is an electronic interconnected RFID lockset carrying a 3-hour fire rating. The Deltana CL300ILC is a Grade 2 commercial interconnected lock whose latch is UL listed with a 1/2 inch throw. Where the door schedule calls out a specific hourly rating on the lockset, specify against that rating directly rather than against grade.

Both are single locking interconnected entrance locksets that accept a keyed cylinder, and the Deltana CL300ILC is supplied on a Schlage C type keyway, single cylinder. That keyway is what lets a CL300ILC be brought onto an existing Schlage C keying system on a building that already runs one. The Schlage CS210-B500 is a Grade 2 heavy duty entrance lockset in the CS210 series. Have the cylinders keyed to the building system at order rather than assuming factory keying matches across brands.

Two: Brushed Chrome and Polished Brass. If you are matching hinges and stops across a building, those are the finish families you can hold the CL300ILC to.

Non-clutch means the outside lever stays rigidly connected to the lock when it is locked, rather than spinning free. It is the simpler and more common arrangement. A clutched lever is what you specify when you want a locked outside lever to turn harmlessly so someone forcing it cannot torque the spindle. The CL300ILC is the non-clutch build in steel and zinc.

Commercial. It is a Grade 2 tubular cylindrical lockset in steel and zinc, which is the duty level normally specified for multi-family and light commercial entry doors. If you are trimming out a single house front door and want a handleset look instead, the Schlage Residential Plymouth outside handleset is an entrance-function residential option.

The Deltana CL300ILC Clarendon lever comes in brushed chrome and polished brass. The Dormakaba InSync RI5100G-26D interconnected latch and deadbolt unit is supplied in satin chrome with a Gala lever. Where a property is standardizing lever style and finish across a building, brushed chrome on the Clarendon lever is the closer visual match to a satin chrome fleet than polished brass.
