Sargent 640 BLACK – Frequently Asked Questions

1) What exit devices does the Sargent 640 top and bottom strike work with?
The Sargent 640 top and bottom strike is made for Sargent AD8400 and AD8600 series exit devices. It is a genuine Sargent replacement part built to the original device specification, so it drops onto those two series without modification. If your device is a different Sargent series, this is not the strike for it.
2) My AD8600 exit device latches at the top but not the bottom. Do I need a new device?
Not necessarily. On AD8400 and AD8600 vertical rod devices the strikes are a serviceable component, and the 640 is the factory top and bottom strike offered as a replacement part. Worn, bent, or missing strikes are a common cause of one end failing to latch, and swapping them is far less work than replacing the device.
3) Is the Sargent 640 one strike or a top and bottom pair?
It is the top and bottom strike set for a vertical rod exit device, meaning it handles latching at both the head and the sill of the opening rather than at a single point. That is what keeps a vertical rod device aligned and holding at both ends of the door.
4) Is the Sargent 640 an aftermarket strike or a factory part?
Factory. The 640 is an authentic Sargent component built to original manufacturer specification for the AD8400 and AD8600 series, which matters on spec'd commercial openings where the hardware schedule calls for manufacturer parts.
5) Can I use the Sargent 640 strike on a residential door?
The 640 strike is a commercial part. It is catalogued as commercial-only hardware and is intended for high traffic openings in offices, schools, healthcare, retail, warehouses, multi-tenant residential buildings and government facilities. On a house door there is no AD8400 or AD8600 exit device to mount it against, so it has no application there.
6) What finish does the Sargent 640 strike come in?
The 640 strike is offered in a single standard finish, so there is no finish selection to make when ordering. If you are matching visible hardware across a run of openings, note that strikes for the top and bottom of a vertical rod device sit at the head and threshold where they are largely out of sight.
