PDQ 649001C – Frequently Asked Questions

1) What exactly is the PDQ 649001-C part?
It's the head chassis for a PDQ concealed vertical rod exit device in the narrow stile configuration, part number 649001-C. The chassis is the core mechanism the push bar and vertical rods tie into. It's sold as a factory replacement part only, not as a complete exit device, so it goes into an existing PDQ device that already has its rods, covers, latches and trim in place.
2) Which PDQ exit devices does the 649001-C head chassis fit?
It is a genuine PDQ service part for the PDQ 6300 Series wide stile and 6400 Series narrow stile exit devices. Since 649001-C is the narrow stile concealed vertical rod chassis, it belongs in a narrow stile CVR device within that family. PDQ doesn't publish cross-brand fit for it, so don't plan on dropping it into a Von Duprin, Precision or Detex device.
3) Can I use the 649001-C chassis on a fire rated door opening?
PDQ offers both panic rated and fire rated head chassis as replacement items in this range, so the rating is determined by the specific chassis you order rather than by the device alone. If the opening is a fire door, confirm with the chassis you receive that it's the fire rated version, because a panic-only chassis on a fire rated assembly voids the labeled opening.
4) My PDQ exit device is a surface vertical rod, not concealed. Is this the right chassis?
No. 649001-C is the concealed vertical rod chassis, where the rods run inside the door. A surface vertical rod device has its rods on the face of the door and uses a different chassis. PDQ's replacement range covers rim, surface vertical rod, concealed vertical rod and mortise configurations, so order the chassis that matches the device type already on the door.
5) Do I have to replace the whole exit device, or can I just swap the chassis?
The chassis can be swapped on its own. PDQ makes these as factory replacement and conversion parts specifically so an installed device can be serviced or upgraded without replacing the whole unit. For a property manager with a row of matching PDQ openings, that means you keep the existing push bars, covers and rods and only renew the failed mechanism.
6) What other PDQ parts might I need when rebuilding a 6400 Series concealed vertical rod device?
Alongside the head chassis, PDQ's replacement range for the 6300 and 6400 Series includes latchbolts, rods and connectors, push bars, covers and end caps, strikes and shims, dogging and alarm conversion kits, screwpacks, drill guides and signal switches. On a CVR rebuild the rods, connectors and top latch are the usual companions, and the screwpack is worth adding if the original fasteners are stripped.
7) Can I add cylinder dogging or an alarm to an existing PDQ exit device instead of buying a new one?
Yes. PDQ sells conversion kits in this parts range that add cylinder dogging or an alarm to an already installed 6300 or 6400 Series device. Note that the 649001-C head chassis itself is a straight replacement part, not a conversion kit, so dogging or alarm functions come from the separate kit.
8) Is the PDQ 649001-C chassis for commercial or residential use?
Commercial. It's commercial door hardware, a chassis-type service part for panic and fire exit devices, which is the kind of hardware you find on egress doors in schools, healthcare, retail and multi-family common areas rather than in a house.
