Sargent 10-2577 26D – Frequently Asked Questions

1) Will the Sargent 10-2577 lock body work with my existing 70-10G44 mortise lock?
That is exactly what the 10-2577 is built for. It is a replacement lock case for the Sargent 70-10G44 mortise lock series, so it drops into the existing mortise pocket and works with the trim and cylinder already on the door. If your mortise lock is a different Sargent series or another brand, this case will not be the right part.
2) Does the Sargent 10-2577 lock case take a small format interchangeable core?
Yes, the 10-2577 comes with SFIC prep, so it accepts a small format interchangeable core cylinder. That lets you drop the case into an existing SFIC master key system without rekeying the building. If your opening uses a conventional mortise cylinder rather than an IC core, this prep is not the one you want.
3) What do I actually get with the Sargent 10-2577, and do I need to order trim or a cylinder too?
The 10-2577 is the lock body (case) only. Levers, roses or escutcheons, and the SFIC core itself are separate. Facilities crews buy it to restore function on a 70 Series mortise lock without replacing the whole lockset, so plan to reuse your existing trim and core unless those are damaged too.
4) Can I use the 10-2577 to convert a conventional-cylinder Sargent mortise lock over to interchangeable core?
Swapping to the SFIC-prepped 10-2577 case is how you get IC core capability in a 70-10G44 opening, since the case is what carries the cylinder prep. You will still need the SFIC core and the correct cylinder retention hardware for your keying system, and the existing trim has to be the 70 Series trim the case was built for.
5) What finishes does the Sargent 10-2577 lock body come in?
Twelve finishes: 03 bright brass, 04 satin brass, 09 bright bronze, 10 satin bronze, 10B dark oxidized satin bronze oil rubbed, 10BL dark oxidized satin bronze clear coated, 15 satin nickel, 20D dark statuary bronze, 26 bright chrome, 26D satin chrome, BSP black suede powder coat and WSP white suede powder coat. Match it to the trim already on your other openings so the building stays consistent.
6) Is the Sargent 10-2577 lock case suitable for a school or hospital door, or is it a residential part?
It is a commercial-grade part, used on office buildings, schools, hospitals, government buildings, hotels and multi-tenant residential, warehouses and retail. Sargent builds it as a maintenance replacement for the 70 Series mortise platform, which is the kind of hardware those facilities standardize on.
