PDQ 649001R – Frequently Asked Questions

1) What exactly is the PDQ 649001-R part?
The 649001-R is a panic rated head chassis for a rim-type, narrow stile PDQ exit device. The head chassis is the mechanism housing at the end of the device where the push bar connects and the rim latch is driven, so this is the working core of the device rather than a cover or trim piece. It is a genuine PDQ factory part sold for replacement only, not as a complete exit device.
2) Can I buy the 649001-R on its own to fix a PDQ exit device, or do I need a whole new device?
It is sold on its own as a service part. PDQ offers factory replacement and conversion parts for the 6300 and 6400 Series so an installed device can be serviced or upgraded without pulling the whole unit off the door. The 649001-R covers the case where the head chassis itself is worn or damaged and the rails, covers and strike are still good.
3) Will the 649001-R head chassis fit a PDQ 6300 wide stile device?
No. The 649001-R is the narrow stile rim chassis. The PDQ parts program covers both the 6300 Series wide stile and 6400 Series narrow stile devices, and wide stile and narrow stile chassis are not interchangeable, so a wide stile 6300 needs the wide stile chassis instead.
4) Is the 649001-R the right chassis for a fire rated exit device?
No, this one is the panic rated version. PDQ lists both panic rated and fire rated head chassis as separate replacement parts, so a labeled fire door assembly needs the fire rated chassis. Putting a panic rated chassis on a fire rated device is not a like-for-like repair.
5) My PDQ device latches at the top and bottom of the door, not at the frame edge. Is this the chassis I need?
No. The 649001-R is a rim chassis, which drives a latchbolt into a surface strike on the frame stop. If your device throws rods to the head and threshold it is a surface or concealed vertical rod device, and PDQ supplies separate chassis parts for rim, surface vertical rod, concealed vertical rod and mortise configurations. Match the chassis to the device type you have.
6) Does the 649001-R come with a push bar, end cap or strike?
It is the head chassis only. PDQ catalogs latchbolts, rods and connectors, push bars, covers and end caps, strikes and shims, and screwpacks as separate replacement items, so if the push rail, cover or strike on your device is also damaged those are ordered individually alongside the chassis.
7) Can I add cylinder dogging or an alarm while I am replacing the chassis?
Yes, PDQ sells conversion kits that add cylinder dogging or an alarm to an installed 6300 or 6400 Series device, along with signal switches. If you are already pulling the device apart to swap the head chassis, that is the practical time to order the conversion kit and do both at once.
8) Is this PDQ chassis a commercial-duty part or for residential doors?
Commercial. The 649001-R is a door hardware service part for PDQ commercial exit devices, the kind of panic hardware used on egress doors in schools, offices and multi-family common areas. It is not a residential item and there is no residential equivalent of this chassis.
9) Is the PDQ 649001-R a genuine factory part or an aftermarket copy?
Genuine PDQ. Part number 649001-R is a factory replacement component for PDQ exit devices, which matters on panic hardware because a non-factory chassis in a listed device puts the device outside the configuration PDQ built and rated.
