About this item
The Accentra (Yale) 1220 is a 7-pin Large Format Interchangeable Core (LFIC) in 626 satin chrome, also known in the field as the Yale A600 core, A600 core, or 1220/7. The 1220 installs in Yale and Accentra mortise locks, cylindrical locks, and exit device trims prepped for the Yale LFIC format, and can be keyed in conjunction with standard Yale cylinders in the same key system. The 1220 is the 7-pin configuration in the Yale LFIC line; the 1210 is the 6-pin version. SKU: 1220.
What "Yale A600 core" means and how it maps to the Accentra 1220
Yale hardware is now marketed under the Accentra brand name as part of ASSA ABLOY. The product formerly known in the market as the Yale A600 core is the Accentra 1220. The model number, pin count, physical dimensions, and system compatibility have not changed under the Accentra brand name. If a hardware specification, a parts list, a facility's key control records, or a locksmith's ordering system references an A600 core, a Yale A600, or a 1220/7, the Accentra 1220 is the current stocked product that fulfills that specification.
The 1220 is a standard large format interchangeable core. It removes and installs using a control key in seconds without any tools or disassembly of the lock housing, which is the fundamental operational advantage of any interchangeable core system. For the 6-pin version of the Yale LFIC core, the Accentra Yale 1210 6-pin interchangeable core is also stocked. For the full IC core range at American Locksets, browse the IC cores catalog.
Why 7-pin LFIC cores are specified over 6-pin in complex master key systems
The pin count in an interchangeable core affects the depth of the master key hierarchy the system can support. A 6-pin core provides a usable key change count suited to small and medium facilities with a simple master and grand master structure. A 7-pin core extends that capacity significantly, allowing more individual change key positions, more master key levels, and more sub-master key groups within the same system before key cuts begin to conflict.
Seven-pin cores are the correct specification for large institutional facilities, universities, hospital campuses, government buildings, and any property where the key system has multiple levels of access authority across a large number of openings. Specifying 7-pin cores from the outset also provides headroom for future system expansion without requiring a complete rekey. For cylinders, cores, and key blanks across Yale keyway series, the cylinders, cores, and keys section covers the available options.
Where the Accentra 1220 installs and what LFIC housing compatibility looks like
The 1220 installs in Yale and Accentra mortise lock bodies, cylindrical lock housings, and exit device trim cylinders that are prepped for the Yale Large Format Interchangeable Core format. The housing geometry for the Yale LFIC is the same across the full line of Yale and Accentra LFIC-prepped hardware, so the 1220 installs in any Yale LFIC housing regardless of the specific lock function or hardware series.
The 1220 does not install in SFIC (Small Format Interchangeable Core) housings, which use a different and physically smaller core geometry. Confirm that the lock housing is prepped for Yale LFIC before ordering. For the Yale LFIC rim cylinder housing for exit device applications, the Accentra Yale 1193 LFIC rim cylinder is stocked as the exit device housing that accepts this core format. For the complete commercial lock and hardware range at American Locksets, browse the commercial locks section.
Confirm the housing is Yale LFIC format before ordering. Also known as: Yale A600 core, A600 core, 1220/7. Finish: 626 satin chrome.
