Accentra K660 626 – Frequently Asked Questions

1) Does the Accentra K660 cylinder housing come with a core, or do I need to order one separately?
The K660 ships less core. It is the mortise housing only, so you order the small format interchangeable core separately and drop it in. That is the point of an SFIC setup: the core carries the keying, and it can be swapped later with a control key without pulling the lock apart. If you are stocking these for a building, plan on one housing plus one SFIC core per opening, plus the control key for the system.
2) What does the 1-3/8 inch on the Accentra K660 refer to?
That is the length of the mortise cylinder housing, measured from the face of the lock body out. It is the standard mortise cylinder length for most commercial mortise locksets on a typical door and trim setup. If your existing cylinder sits proud of the trim or recesses too deep, cylinder length is what you are correcting, and the K660 is the 1-3/8 inch option.
3) Can I use the Accentra K660 on a cylindrical or bored lock?
No. The K660 is a mortise cylinder housing, threaded to screw into a mortise lock body and driven by a cam. A cylindrical lockset takes a key-in-knob or key-in-lever core, or a rim cylinder for an exit device, and none of those accept a mortise cylinder. If the lock in your door is a mortise case set into the edge of the door, this is the right housing; if it is a bored lock through the face of the door, it is not.
4) I need a large format interchangeable core mortise housing, not small format. What should I get instead?
The K660 is small format only, so it will not take an LFIC core. For large format, the Kaba Ilco S26506 is a mortise large format IC core convertible housing in the Schlage size. Check which core your system actually uses before ordering either one: LFIC cores are noticeably larger than the figure-eight small format core, and the two are not interchangeable in the same housing.
5) What other housing takes a small format interchangeable core if the Accentra K660 does not suit the opening?
The Kaba Ilco R2800 Series is a small format IC core convertible housing, the same core family the Accentra K660 is built around - the K660 is a 1-3/8 inch SFIC mortise housing that ships less core and accepts standard small format interchangeable cores. Both let a locksmith drop in an already-keyed SFIC core rather than pinning a fixed cylinder, so a facility running one SFIC keyway can stay on that keyway either way. Confirm the cylinder length and the mortise prep in the lock case before you commit, since the K660 is specified at 1-3/8 inch.
6) Will a Kaba Ilco S26506 housing accept the same core as an Accentra K660?
No. The Kaba Ilco S26506 is a large format IC core convertible housing in the Schlage size, while the Accentra K660 is built for standard small format interchangeable cores. Large format and small format cores are different sizes and are not cross-compatible, so a shop stocked with SFIC cores cannot key an S26506 from that stock and vice versa. Both are mortise housings - the S26506 is listed with a mortise product function and the K660 is a mortise cylinder housing - so the confusion is easy to make at the counter. Decide by which core format the building is already keyed to.
7) What finishes does the Accentra K660 SFIC mortise housing come in?
Two: 626 satin chrome and 613E dark oxidized satin bronze equivalent. 626 is the default on most commercial door hardware, so it is the one that blends in on a building already running satin chrome levers and exit trim. 613E is the darker bronze option for openings finished in oil-rubbed or dark bronze. Match the cylinder to the trim on the door, not to the lock body, since the cylinder face is what shows.
8) What is the difference between the Accentra K660 and the Kaba Ilco R2800 SFIC housing?
Both take small format interchangeable cores. The K660 is the Accentra mortise housing in 1-3/8 inch, in satin chrome or dark oxidized satin bronze. The Kaba Ilco R2800 Series is a small format IC core convertible housing. If you are standardizing a building on one manufacturer's cylinder line so your keying records and control keys stay in one system, that brand consistency is usually the deciding factor rather than the housing itself.
9) Can I keep my existing keys if I replace a mortise cylinder with the Accentra K660?
The housing carries no keying at all, so the keys are decided entirely by the SFIC core you put in it. Order the core cut to your existing system, or have it pinned to your keyway and master key schedule, and the K660 works with the keys already in your tenants' hands. If you are coming off conventional mortise cylinders rather than SFIC, you are changing key systems at that opening and will need cores keyed to match whatever standard you are moving to.
10) We are standardizing a facility on large format Schlage-size cores - what mortise housing do we use instead of the Accentra K660?
Use the Kaba Ilco S26506, a large format IC core convertible housing in the Schlage size with a mortise product function. The Accentra K660 is the small format equivalent for mortise locksets, accepting standard SFIC cores, so it is the wrong housing for a large format keying program. Institutional buyers converting a whole building generally pick the housing that matches the core format already in the master key system, then order the mortise locksets to suit.
11) Is the Accentra K660 housing suitable for a high traffic commercial building?
It is a commercial-rated part, built for mortise locksets in commercial door hardware systems. Typical applications are office buildings, schools, hospitals, government facilities, multi-tenant residential, warehouses, and retail. For a property manager or MRO buyer, the practical draw is key management: with SFIC you rekey an opening by swapping the core in seconds instead of pulling the lock and pinning a cylinder on a bench, which matters when you are turning units or handling a lost master key.
12) Does the finish of the Accentra K660 need to match the Kaba Ilco housing already on the other doors?
The Accentra K660 mortise cylinder housing comes in 613E dark oxidized satin bronze equivalent and 626 satin chrome, so the face that shows at the door can be matched to the rest of the trim. The Kaba Ilco R2800 Series small format IC housing and the S26506 large format mortise housing are the cross-brand alternatives, and finish on a cylinder housing is a visible detail on the exterior of the door - a property manager replacing one door in a run will usually pull the finish that matches the neighbors rather than the brand.
