PDQ 631617 – Frequently Asked Questions
1) What is the PDQ 631617 and what does it go on?
The 631617 is the mullion fire strike for the PDQ 9300 Series removable mullion, the mullion that stands between a pair of doors fitted with 6300R or 6400R rim exit devices. It is the strike the rim device latch engages on the mullion, and it ships with its fasteners.
2) Can I just order the PDQ 631617 mullion fire strike outright?
No. The 631617 is sold as a replacement part only, and PDQ requires the order number from the original mullion purchase before it will be supplied. If you are specifying a new opening, the strike comes as part of the 9300 Series mullion rather than as a separate line item, so dig out the original order paperwork before you try to buy the strike on its own.
3) Do I need extra screws or anchors to install the PDQ 631617 strike?
No separate hardware purchase is needed. Fasteners are included with the 631617 strike, so you are replacing like for like on the mullion with what comes in the package.
4) Will the PDQ 631617 strike work on a mullion from another brand?
Treat it as PDQ 9300 Series only. The 631617 is built for the PDQ 9300 removable mullion and nothing else is stated as compatible, so a Von Duprin, Precision or Detex mullion needs that manufacturer's own strike.
5) My 9300 mullion keeps getting stored loose in the shop. Is there a PDQ part for that?
Yes, that is the 639081 storage kit, a separate PDQ accessory for the same 9300 Series mullion. It includes what you need to mount and store the mullion on a wall when it has been taken out of the opening. The 631617 fire strike is a different part and does not include any storage hardware.
6) Is the PDQ 631617 mullion strike rated for commercial openings?
It is a commercial door hardware part, used on fire rated pairs where a 9300 Series removable mullion carries rim exit devices. For the published ratings and mounting details of the mullion assembly itself, the 9300 Series architectural submittal sheet is the document to put in front of an AHJ or on a submittal package.
