PDQ 639704RN630 – Frequently Asked Questions

1) What exactly is PDQ part 639704RN and what does it cover on the exit device?
639704RN is the standard head/chassis cover for a PDQ rim exit device in the narrow stile configuration. It is the cover that fits over the head chassis end of the device, not the chassis itself. If the chassis mechanism is what failed, you need a head chassis assembly instead; this is the cosmetic/protective cover only.
2) Will the PDQ 639704RN cover fit a wide stile 6300 Series rim device?
No. 639704RN is the narrow stile rim cover, so it is sized for the 6400 Series narrow stile rim device. A wide stile 6300 Series rim device takes the wide stile version of the head/chassis cover. Ordering the narrow cover for a wide device leaves you with a part that will not seat on the chassis.
3) Does this cover work on surface vertical rod or mortise PDQ devices?
It is specified for rim devices. The PDQ replacement parts range does cover surface vertical rod, concealed vertical rod and mortise configurations, but those device types use their own head/chassis covers. For an SVR, CVR or mortise device, order the cover called out for that configuration rather than 639704RN.
4) What finishes does the PDQ 639704RN head cover come in, and how do I match the rest of my doors?
Seven finishes: 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. Match the finish code stamped or specified on the existing device rather than matching by eye, since 625 bright chrome and 626 satin chrome read very differently side by side on a glass front entry. 630 satin stainless is the common choice on commercial aluminum storefront.
5) How do I order the right PDQ 639704RN part number for my finish?
The finish code is appended to the base number. Satin chrome is 639704RN626, satin stainless is 639704RN630, bright brass is 639704RN605, and so on through 606, 613E, 622 and 625. Give the full suffixed number when ordering so the cover arrives in the finish that matches the device already on the door.
6) Can I replace a cracked exit device cover without pulling the whole panic device off the door?
That is what these PDQ parts are for. 639704RN is a factory replacement cover for an installed 6300/6400 Series device, so a damaged or vandalized cover can be swapped without buying a new exit device or re-prepping the door. Useful for property managers keeping a fleet of storefront entries looking consistent.
7) Is the PDQ 639704RN cover rated for commercial use?
Yes, it is a commercial door hardware part, supplied as a genuine PDQ component for the 6300 and 6400 Series exit devices used on commercial and multi-family openings. It is a cover, so it is not the rated element of the device; panic and fire rated head chassis assemblies are separate parts in the same PDQ parts range.
8) My PDQ exit device needs more than just the cover. What other parts are available in the same family?
The same PDQ replacement range includes head chassis assemblies, latchbolts, rods and connectors, push bars, end caps, strikes and shims, drill guides, screwpacks, signal switches, and conversion kits that add cylinder dogging or an alarm to a device already hung on the door. So a full service of a 6300 or 6400 Series device can be done part by part.
