Schlage B610-204 626 – Frequently Asked Questions

1) Will the Schlage B610-204 cylinder housing work on a 2 inch thick door?
Yes. The B610-204 housing covers door thicknesses from 1-3/8 inches through 2-1/4 inches, so a 2 inch door is within range. That span also covers the standard 1-3/4 inch commercial door and the older 1-3/8 inch interior door, so one housing part number handles most openings in a mixed building.
2) Does the B610-204 take a small format interchangeable core, and does the core come with it?
The B610-204 is built to accept a small format interchangeable core (SFIC), which is what lets you pull and swap a core with a control key instead of rekeying the lock. It's the housing only, a replacement part for B500 Series deadbolts, so the SFIC core and the keys are ordered separately to match your existing key system.
3) Which Schlage deadbolts does the B610-204 housing fit?
It's built for the Schlage B500 Series exterior deadbolts in single and double cylinder SFIC configurations. It is not a universal housing, so if the deadbolt on the door is a different Schlage series or a conventional (non-SFIC) cylinder lock, this is the wrong part.
4) What finishes does the Schlage B610-204 cylinder housing come in, and how do I match my other doors?
Four finishes: 606 satin brass, 613 oil rubbed bronze, 626 satin chrome, and 643E aged bronze. Match the BHMA finish number stamped or specified on the existing hardware rather than eyeballing the color. 626 satin chrome is the usual choice on commercial openings where the rest of the trim is brushed nickel-looking.
5) I'm replacing a damaged SFIC deadbolt cylinder housing on a commercial door. Do I need the whole deadbolt?
Not if the rest of the B500 Series deadbolt is sound. The B610-204 is sold as an OEM replacement housing so you can service just the cylinder side and keep the existing bolt, strike, and key system in place. Reuse your SFIC core and the opening goes back to the same key.
6) What's the difference between the Schlage B610-204 housing and an IC core convertible housing like the Kaba Ilco R2800?
The B610-204 is model-specific: it fits Schlage B500 Series SFIC deadbolts and nothing else. The Kaba Ilco R2800 Series is a small format IC core convertible housing, meaning it's set up to convert a lock to SFIC rather than being tied to a Schlage deadbolt body. Ilco also makes the S26506, a large format IC core convertible mortise housing in Schlage size, which is for large format cores in a mortise application, not small format deadbolts. If you're servicing an existing B500 deadbolt, the Schlage part is the direct fit.
7) Do I order one B610-204 or two for a double cylinder deadbolt?
The housing is used in both single and double cylinder B500 Series SFIC deadbolt configurations. A double cylinder deadbolt is keyed on both sides, so it takes a housing and a core on each face; count the keyed sides on the opening and order to match.
8) The Kaba Ilco S26506 says Schlage size - can I use it in place of the Schlage B610-204?
No, despite the Schlage reference. The S26506 is a mortise housing built for large format interchangeable cores in the Schlage size, which describes the core dimension it accepts, not compatibility with a B500 deadbolt. The B610-204 is a small format interchangeable core housing made for B500 Series exterior single and double deadbolt configurations. Different lock body and different core format, so the two are not interchangeable.
9) For a facility standardizing on small format interchangeable cores, how do the Schlage B610-204 and the Kaba Ilco R2800 Series differ?
Both accept small format interchangeable cores, so both support tool-free core swaps for key control. The difference is scope: the B610-204 is a genuine Schlage OEM part built for the B500 Series exterior single and double SFIC deadbolt and covers door thicknesses from 1-3/8 inch to 2-1/4 inch, offered in 606 satin brass, 613 oil rubbed bronze, 626 satin chrome, and 643E aged bronze. The Kaba Ilco R2800 Series is a convertible SFIC housing not tied to the B500 deadbolt. If your deadbolts are B500, the B610-204 keeps the assembly matched to its original hardware.
10) Is the B610-204 rated for commercial traffic or is it a residential part?
It's a commercial part, specified for B500 Series hardware in offices, schools, healthcare, government buildings, multi-tenant residential, retail, and warehouse facilities. Facilities standardizing on SFIC key control across a campus use this housing so every exterior deadbolt takes the same core format.
