PDQ 639704BN626 – Frequently Asked Questions

1) What exactly is PDQ part 639704BN, and what device does it fit?
639704BN is the standard head/chassis cover for a PDQ concealed vertical rod exit device in the narrow stile configuration. It is the cover that goes over the head/chassis end of the device, not the chassis itself and not the push bar. It is a genuine PDQ factory part for the PDQ 6300 and 6400 Series exit devices.
2) I have a PDQ surface vertical rod device, not concealed rod. Will the 639704BN cover work?
No. 639704BN is specified for the concealed vertical rod narrow stile configuration. PDQ's replacement range covers rim, surface vertical rod, concealed vertical rod and mortise devices separately, and each configuration carries its own part number, so a surface vertical rod device needs the cover listed for that configuration rather than this one.
3) Can I replace just the damaged cover on a PDQ exit device instead of buying a whole new device?
That is the point of the part. 639704BN is a factory service part, so a scratched, dented or missing head cover on an installed PDQ concealed vertical rod device can be swapped without pulling the device off the door. PDQ supplies the surrounding parts the same way, including head chassis assemblies, latchbolts, rods and connectors, push bars, end caps, strikes, shims and screwpacks.
4) How do I order the right finish of PDQ 639704BN to match the exit devices already on my other doors?
Finish is the only thing you choose on 639704BN, and the part number carries it as a suffix. Seven are offered: 605 bright brass, 606 satin brass, 613E dark oxidized satin bronze, 622 flat black, 625 bright chrome, 626 satin chrome and 630 satin stainless steel. So a satin chrome cover orders as 639704BN626, bright brass as 639704BN605. Read the BHMA finish number off the existing device and order the matching suffix.
5) Does swapping the head cover on a fire rated PDQ exit device change anything about the device?
The cover is a trim piece over the head/chassis; the rating lives in the chassis itself. PDQ offers both panic rated and fire rated head chassis as replacement parts, so if the rating on a door is in question it is the chassis assembly that has to be ordered correctly, not the cover. Match the cover to the device configuration, concealed vertical rod narrow stile in the case of 639704BN.
6) I want to add cylinder dogging or an alarm to an existing PDQ exit device. Is that done with this cover?
No, 639704BN is the cover only. PDQ sells separate conversion kits that add cylinder dogging or an alarm to an installed device, and those are what you order for that work. You may still want the cover if the original is damaged during the conversion.
7) Is the PDQ 639704BN cover suitable for a commercial building, or is it a residential part?
Commercial. It is a door hardware service part for PDQ panic hardware, the kind of exit device used on commercial egress doors, so it fits institutional, multi-family and commercial MRO work rather than residential locksets.
