Delaney LM Series 6-Pin Small Format Interchangeable Core (SFIC) & Key

It's the core only, a 6-pin small format interchangeable core with key, not a deadbolt assembly. You install it into a lock body already prepped for SFIC (a less-core deadbolt or lever). If you need the deadbolt itself as well, order a less-core body to receive it.

That is exactly what small format interchangeable cores are for. Six pin chambers give you the space for master and grand master levels, and because the core pulls with a control key, a locksmith or in-house maintenance tech can rekey an opening in seconds without pulling the lock off the door. For a property manager or MRO buyer standardizing a facility, that is the main reason to spec SFIC prepped hardware over fixed-cylinder locks.

The Arrow E61 26D IC is a single cylinder deadlock with SFIC prep supplied less core, and it lists a door thickness range of 1-3/8 inch to 1-3/4 inch. The Delaney LM Series 300600C is a Grade 1 deadbolt with a 6-pin SFIC core function in US26D dull chrome. Another less-core option is the Deltana CL200LAIC, a Grade 2 interchangeable core deadbolt with a 2-3/4 inch backset. The Arrow and Deltana are Grade 2 where the Delaney is Grade 1, so match the grade your spec calls for.

The Delaney LM Series 300600C is built around a 6-pin small format interchangeable core. If you want a conventional cylinder with a thumbturn on the inside at the same Grade 1 level, the Accentra D111 is a Grade 1 single cylinder deadbolt with a 2-3/8 inch backset and a cylinder x thumbturn function covering 1-3/8 inch to 1-3/4 inch doors, and the Dexter DB1000 single cylinder is Grade 1 cylinder x thumbturn for 1-3/8 inch to 1-7/8 inch doors. The Deltana CL200LM is also a Grade 1 cylinder x thumbturn deadbolt.

US26D dull chrome, which is the standard satin chrome commercial finish. It reads as a match alongside other 26D lever trim and deadbolt roses, so it blends on openings already standardized on satin chrome.

Yes. The LM Series core is classified commercial and Grade 1, so it suits multi-family, institutional and other high-traffic openings rather than light residential duty.

Go with a deadbolt that ships with its cylinder already installed. Grade 1 options we carry include the Dexter DB1000 single cylinder deadbolt, which covers 1-3/8 inch to 1-7/8 inch doors, the Accentra D111 with a 2-3/8 inch backset for 1-3/8 inch to 1-3/4 inch doors, and the Deltana CL200LM single cylinder deadbolt. Those are keyed conventionally, so rekeying means pinning the cylinder rather than swapping a core.

Yes. The Delaney LM Series 300600C is a Grade 1 commercial deadbolt. For lighter duty, the Cal-Royal CB160 is a Grade 2 single cylinder deadbolt with a tamper-resistant cylinder guard, the Dexter DB2000 single cylinder is Grade 2 cylinder x thumbturn for 1-3/8 inch to 1-3/4 inch doors, and the Cal-Royal ED500 is a Grade 3 single cylinder deadbolt with an adjustable backset over the same thickness range. None of those three use an SFIC core, so they will not key into an existing small format core system.

They are not a like-for-like swap. The Corbin Russwin DL3011 and DL3211 are Grade 1 cylindrical deadlocks in a cylinder x blank configuration, meaning no thumbturn on the inside; the DL3011 lists 1-3/4 inch to 2-1/4 inch door thickness and the DL3211 lists 1-3/4 inch. The Delaney LM Series 300600C is a Grade 1 single cylinder deadbolt prepped for a 6-pin small format interchangeable core. Confirm whether your opening needs inside thumbturn operation before substituting.

If a published fire rating is the deciding factor, the Hager 3118 is a Grade 1 classroom deadbolt with a Schlage C keyway and 6-pin cylinder, listed as fire rated for 1-3/8 inch to 1-3/4 inch doors, and the Hager 3215 single cylinder Grade 1 deadbolt with a 1 inch throw carries a fire rating over the same range. The Cal-Royal CRB800 is a Grade 1 heavy duty single cylinder deadbolt with a UL 3-hour fire rated latch. The Delaney LM Series 300600C is a Grade 1 commercial deadbolt taking a 6-pin small format interchangeable core, which is the route to take if keying into an existing SFIC system matters more than a stated rating.

The Arrow E60 is a Grade 2 exit deadlock, non-keyed, with a blank plate on the outside and a thumbturn on the inside, listed for 1-3/8 inch to 1-3/4 inch doors. The Callan 205S is a Grade 3 one-sided half-bore deadbolt for openings that only need operation from one face. The Delaney LM Series 300600C is a keyed Grade 1 deadbolt prepped for a 6-pin small format interchangeable core, so it is the choice when the door must be operated by key from outside.

It ships as a core with a key, so it arrives pinned and operable out of the box. Keying it into an existing master system, or keying a group alike, is a keying request handled at order time rather than something the standard core covers, since the pinning has to match your system's bitting.

Not without changing the door prep. The Dormakaba D900 is a small case mortise dead bolt with a cylinder x thumbturn function, keyed different with SC keyways, and mortise cases require a pocket cut into the door edge. The Delaney LM Series 300600C is a bored deadbolt that installs in a standard cross-bore and edge-bore. If the door already carries a mortise pocket, the D900 or the Arrow 460 mortise strike may be what you actually need.

The Dormakaba Nova-D is an RFID multihousing smart electronic deadbolt, and the Saffire LX-D is an RFID electronic deadbolt with Bluetooth and electronic lock override. The Codelocks CL2200 is an electronic surface deadbolt in a brushed steel finish, rated medium duty, and the CL200 is a surface deadbolt with key override rated light duty. The Delaney LM Series 300600C is a mechanical Grade 1 deadbolt accepting a 6-pin small format interchangeable core, which keeps the opening on your existing key system instead of on credentials.

The Delaney LM Series 300600C is a commercial Grade 1 deadbolt in US26D dull chrome taking a 6-pin small format interchangeable core. For decorative residential entries, the Emtek #11 Tuscany is a lost wax cast bronze deadbolt with a cylinder x thumbturn function, the Baldwin Estates 8011 is a contemporary 1-5/8 inch double cylinder deadbolt, and the Bravura 310SC Elite is a Grade 2 contemporary square deadbolt with cylinder x thumbturn. Those are trim-driven products rather than SFIC-keyed commercial hardware.
