PDQ 649001RF – Frequently Asked Questions

1) What is the PDQ 649001-RF part, and which exit devices does it fit?
The 649001-RF is a genuine PDQ fire rated head chassis for rim, narrow stile exit devices. It is a factory replacement component for PDQ 6300 Series wide stile and 6400 Series narrow stile exit devices, sold for servicing an installed device rather than as a complete exit device. Because it is the narrow stile rim chassis, it goes into a narrow stile rim configuration, not a surface vertical rod, concealed vertical rod or mortise device.
2) Can I use the 649001-RF to replace the chassis on a panic rated PDQ device?
No. The 649001-RF is the fire rated version of the head chassis. PDQ offers both panic rated and fire rated head chassis as separate replacement parts, so a panic only device needs the panic rated chassis, not this one. Match the chassis rating to the device you are servicing; fire rated openings require the fire rated chassis.
3) Will the 649001-RF head chassis work on a wide stile PDQ 6300 exit device?
No. The 649001-RF is built as a narrow stile rim chassis, so it belongs in a narrow stile rim device. A wide stile 6300 Series device takes the wide stile head chassis instead. The PDQ replacement parts range covers both stile widths as well as rim, surface vertical rod, concealed vertical rod and mortise configurations, so order the chassis that matches the device already hung on the door.
4) Do I have to replace the whole exit device, or can I just swap the head chassis?
A single chassis swap is the point of this part. PDQ supplies the 649001-RF and the rest of its service range (latchbolts, rods and connectors, push bars, covers and end caps, strikes and shims, screwpacks and signal switches) so an installed device can be serviced or upgraded without pulling the entire unit off the door. For a maintenance crew standardized on PDQ 6300 and 6400 Series devices, that keeps the existing trim, cylinder and door prep in place.
5) Is the 649001-RF a commercial part, and is it suitable for an aluminum storefront door?
It is a commercial door hardware part. The narrow stile rim configuration is the one used on aluminum storefront and glass front doors, where the stile is too narrow for a wide stile device. The chassis is the fire rated version, so it suits narrow stile openings that carry a fire rating.
6) Can I add cylinder dogging or an alarm when I replace a PDQ exit device chassis?
Those are separate conversion kits, not features of the 649001-RF chassis. PDQ offers conversion kits that add cylinder dogging or an alarm to an already installed 6300 or 6400 Series device, so if you want either function you order the matching kit alongside the chassis. Note that fire rated exit devices are not dogged, so cylinder dogging belongs on panic rated openings only.
7) What else might I need to order with a PDQ replacement head chassis?
Depending on what is worn, the PDQ service range also covers latchbolts, rods and connectors, push bars, covers and end caps, strikes and shims, drill guides and screwpacks. If the chassis is being replaced because the device was damaged, inspect the latchbolt and strike at the same time, and have a screwpack on hand so you are not reusing stripped fasteners.
8) Is the PDQ 649001-RF a genuine factory part or an aftermarket substitute?
It is a genuine PDQ factory replacement part, part number 649001-RF. For an institutional or MRO buyer keeping fire rated openings in compliance, using the manufacturer's own chassis is what keeps the device as originally listed rather than a field modified assembly.
