Sargent 644 BLACK – Frequently Asked Questions

1) Which Sargent exit devices does the 644 surface strike work with?
The Sargent 644 surface double door strike is made for Sargent 2828, 3828, 8800 and 9800 Series exit devices. If the device on your opening is one of those four families, the 644 is the matching strike. For any other brand of exit device, or a Sargent series outside those four, this is not the right strike.
2) Do I need a mullion for this strike, or does it mount on the inactive door?
It is a surface-mounted strike for double door openings, so it fastens to the surface of the frame or mullion rather than being mortised in. That gives the latch a strike point where two leaves meet, on both the active and inactive side of the pair. Nothing in the door face has to be routed out to use it.
3) My Sargent exit device latch won't hold on the pair of doors. Do I replace the whole device?
Not necessarily. On a pair, worn or bent strikes are a common cause of the latch not catching, and the 644 is sold as a standalone replacement strike for the 2828, 3828, 8800 and 9800 Series. Swapping the surface strike restores the latching point without pulling the exit device off the door.
4) Is the Sargent 644 an original Sargent part or an aftermarket copy?
It is a genuine Sargent replacement component, model 644, not a generic equivalent. For a facility standardizing on Sargent exit hardware, that matters: the strike geometry is the one the 2828, 3828, 8800 and 9800 devices were built to latch into.
5) Is this strike rated for a high-traffic commercial opening or is it light duty?
Commercial duty. The 644 is catalogued as a commercial exit device part, built for the kind of double door egress points you find in offices, schools, hospitals and warehouses where the doors cycle all day.
6) What finish options does the Sargent 644 strike come in?
The 644 is offered in a single standard finish, so there is no finish code to specify when ordering. If you are matching visible hardware on a storefront or lobby pair, plan on the standard finish being what arrives.
