Sargent 904 LHR 26D – Frequently Asked Questions

1) What does LHR mean on the Sargent 904 mortise lock body, and how do I know if that's the hand I need?
LHR stands for left hand reverse. Stand outside the door on the side that swings toward you: if the hinges are on your left and the door pulls toward you, that opening is left hand reverse. The Sargent 904 mortise lock body is built specifically for LHR openings, so a right hand or right hand reverse door needs the opposite hand. Handing is not field-reversible on this part, so confirm the swing before ordering.
2) Which Sargent exit devices does the 904 mortise lock body fit?
It is ordered against a specific Sargent exit device series: 83/89/9904, 83/89/9910, 83/89/9916, 83/89/9928, 83/89/9940, 83/89/9944, 83/89/9963, 83/89/9975, 83/89/9976, 83/8973, 83/8974, and 8966. Pick the series that matches the device already on the door, since that selection is what determines the correct lock body for your assembly.
3) Is the Sargent 904 a complete exit device, or just a part?
Just the mortise lock body. It is a replacement component that drops into an existing Sargent mortise exit device assembly to restore latching and locking function. Rails, trim, cylinders, and strikes are separate items, so if you are hanging new hardware you need the full device, not this.
4) What finishes does the Sargent 904 mortise lock body come in, and does the finish need to match my existing device?
Nine finishes are offered: 03 bright brass clear coated, 04 satin brass clear coated, 10 satin bronze clear coated, 10B dark oxidized satin bronze oil rubbed, 10BL dark oxidized satin bronze clear coated, 20D dark statuary bronze lacquered, 26 bright chromium plated over nickel, 26D satin chromium plated over nickel, and BSP black suede powder coat. Most of the lock body sits inside the door pocket, but matching the finish to the rest of the device keeps any visible faceplate consistent across a run of doors, which matters when you are standardizing a building.
5) I manage a building with several Sargent 80 Series mortise exit devices. Can I stock one 904 lock body for all of them?
Not one part number for all of them. The 904 is ordered by both hand and device series, so an LHR opening on an 83/89/9975 device and an LHR opening on an 8966 device take different selections, and any right-hand opening takes the opposite hand entirely. Survey your doors by device series and swing first, then stock accordingly.
6) Is the Sargent 904 mortise lock body suitable for a high-traffic commercial opening like a school or hospital?
Yes, that is what it is built for. The 904 is a commercial-grade component used in offices, schools, healthcare facilities, retail and hospitality, industrial buildings, multi-tenant residential, and government buildings. It is not a residential part.
