Sargent 642 BLACK – Frequently Asked Questions

1) Which Sargent exit devices does the 642 full mortise strike work with?
The Sargent 642 full mortise strike is made for Sargent 2828, 3828, 8800 and 9800 Series exit devices. It is an OEM-matched replacement keeper for those families, so if the device on the door is one of those four series, the 642 is the strike that goes with it.
2) Is the 642 a complete exit device or just the strike?
Just the strike. The 642 is the keeper half only, the part that mounts in the frame and receives the bolt. The exit device itself, trim, and any rods or cylinders are separate. Order it when you are repairing or servicing an installed Sargent device, not when you need a whole new device.
3) What does a full mortise strike do differently than a surface-applied strike?
A full mortise strike gets cut into the frame so it sits flush, giving the latch or lock bolt a recessed keeper rather than a plate screwed onto the face of the jamb. That means the frame has to be mortised for it. If your frame is only prepped for a surface strike, you need a surface-type keeper instead, not the 642.
4) Am I buying a genuine Sargent part or an aftermarket copy?
It's a genuine Sargent component, classified as an OEM-matched replacement part, so fit, finish and function line up with the 2828, 3828, 8800 and 9800 Series assemblies it drops into. For a property manager standardizing on Sargent across a building, that avoids the mismatch you get from generic keepers.
5) Is the Sargent 642 strike suitable for a high-traffic commercial opening?
Yes. The 642 is a commercial-grade part, catalogued for commercial rather than residential use, and Sargent builds it for the traffic seen in offices, schools, hospitals, retail, warehouses, multi-tenant residential and government buildings.
6) What finish does the Sargent 642 mortise strike come in?
One finish only: Black. There is a single orderable configuration, so there is no finish choice to specify on the order. If you are matching bright brass or satin chrome trim on the opening, be aware the strike itself will be black.
