Sargent 650 BLACK – Frequently Asked Questions

1) Which Sargent exit devices does the 650 top strike fit?
The Sargent 650 Standard Top Strike is built for the (12/NB)MD8400, (12/NB)MD8600 and (12)WD8600 exit device series. Those are the configurations it is made to engage. If your device is outside those three series, the 650 is not the strike for it.
2) My Sargent vertical rod device won't latch at the top of the door. Is replacing the top strike the fix?
If the top latch is missing or dragging on a Sargent MD8400, MD8600 or WD8600, a worn or bent top strike is a common cause, and the 650 Standard Top Strike is the part that restores that engagement. It provides the strike geometry and engagement profile those series expect, so the top latch seats the way it did originally. Bear in mind a top latch that won't catch can also come from rod adjustment, so check rod length and door alignment at the same time.
3) Do I have to modify the door or frame to install the Sargent 650 top strike?
No modification is called for. The 650 is a drop-in replacement for the supported Sargent series, meaning it goes back into the existing prep and restores function without reworking the frame or the rest of the device.
4) Is the Sargent 650 an OEM part or an aftermarket copy?
It comes from the Sargent product line itself, so fit, form and function line up with the original exit device assembly rather than approximating it. For a facility standardized on Sargent exit devices, that matters when you are stocking spares.
5) Ordering spares for a building full of Sargent exit devices, how many part numbers do I need for the top strikes?
If your openings run a mix of (12/NB)MD8400, (12/NB)MD8600 and (12)WD8600 devices, one part covers all of them. The 650 Standard Top Strike is shared across those three series, so a property manager or MRO buyer can stock a single strike rather than one per device family.
6) Is the Sargent 650 top strike rated for commercial traffic, or is it a light-duty part?
Commercial. The 650 is classified as a commercial door hardware component, built for the repeat cycling you see in offices, schools, hospitals, retail, warehouses, multi-tenant residential and municipal buildings. It is not a residential-duty item.
7) What finish does the Sargent 650 top strike come in?
There is one option on the 650 Standard Top Strike: Standard finish. No other finish choice is offered, so there is nothing to specify beyond the part itself when you order.
