PDQ 639712 – Frequently Asked Questions
1) Will the PDQ 639712 strike work with a surface vertical rod or mortise exit device?
No. The 639712 is a rim mullion strike, so it only serves a rim device whose latch throws into a strike on the mullion. Surface vertical rod and concealed vertical rod devices latch at the head and threshold, and a mortise device latches into the frame or the opposite leaf, so none of those need this part. PDQ's 6300 and 6400 replacement range covers strikes and shims for those other configurations separately.
2) Do I need a fire-rated mullion strike for a fire-rated pair of doors with rim exit devices?
On a fire-rated pair, every component in the latching path has to be the rated part, and the 639712 is PDQ's fire / windstorm rim mullion strike for exactly that application. Pair it with a fire-rated head chassis on the device; PDQ offers panic-rated and fire-rated head chassis as replacement items in the same 6300/6400 parts range, and mixing a panic-only chassis into a fire opening defeats the rating.
3) I manage a building with PDQ exit devices on glass front and storefront doors. Is this strike the same part for narrow stile doors?
Yes. The 639712 mullion strike is listed for both the 6300 Series wide stile and the 6400 Series narrow stile PDQ exit devices, so the same part covers aluminum narrow stile storefront pairs and wider hollow metal or wood pairs, as long as the devices are rim type latching into a mullion.
4) Is the PDQ 639712 the right strike for a windstorm or hurricane-rated opening?
Yes, 639712 is PDQ's combined fire / windstorm rim mullion strike, so it is the version specified where the mullion assembly has to hold up under windstorm loading as well as fire conditions. It is a commercial door hardware part, not a residential one.
5) Can I replace just the mullion strike instead of buying a whole new exit device?
That is the point of the 639712. PDQ sells these as factory replacement and conversion parts, so a worn or damaged mullion strike, latchbolt, rod, push bar, cover or end cap can be swapped and the installed device kept in service. Screwpacks, shims and drill guides are also part of the same range for adjustment during the swap.
6) Is PDQ 639712 a genuine factory part or an aftermarket copy?
639712 is a genuine PDQ part, supplied as a factory replacement for the 6300 and 6400 Series exit devices. On a fire or windstorm opening that matters, since substituting a non-factory strike can put the listed assembly in question.
