PDQ 639154626 – Frequently Asked Questions
1) What part is PDQ 639154 and where does it go on an exit device?
PDQ 639154 is the top latchbolt for a surface vertical rod exit device. It's the bolt that engages the strike at the head of the frame on a 6300 or 6400 Series surface vertical rod device, so it's the piece you replace when the door stops latching at the top or the bolt is worn or damaged. Genuine PDQ factory part, sold as a single latchbolt rather than a complete vertical rod assembly.
2) Will the 639154 top latchbolt work on a PDQ 6400 narrow stile device, or only the 6300?
Both. The 639154 latchbolt is a factory replacement part for PDQ 6300 Series wide stile and 6400 Series narrow stile exit devices. What matters is that the device is a surface vertical rod configuration, not rim, concealed vertical rod or mortise. If your device latches into a strike at the head with an exposed rod running up the door face, this is the right top bolt.
3) My PDQ exit device has a concealed rod. Can I use the 639154 latchbolt?
No. The 639154 is the top latchbolt for a surface vertical rod (SVR) device, where the rod runs on the face of the door. Concealed vertical rod devices use their own latch parts, and the PDQ 6300 and 6400 replacement part range covers concealed vertical rod separately. Identify your device configuration first, then order the latchbolt that matches it.
4) What finishes does the PDQ 639154 top latchbolt come in?
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. Order by appending the finish code to the part number, so 639154605 is the bright brass bolt. If you're servicing one leaf of a pair, match the code already stamped on the device so the new bolt doesn't read differently from the rest of the hardware.
5) Can I fix a PDQ exit device that won't latch at the top without replacing the whole device?
Yes, that's the point of the PDQ parts program. The 6300 and 6400 Series replacement range includes head chassis assemblies, latchbolts, rods and connectors, push bars, covers and end caps, strikes and shims, dogging and alarm conversion kits, screwpacks and signal switches, so an installed device can be serviced or upgraded piece by piece. For a top bolt that no longer engages, the 639154 top latchbolt is the replacement; a worn or misaligned strike or a rod out of adjustment is the other thing to check before you condemn the bolt.
6) Is 639154 a genuine PDQ part or an aftermarket copy?
Genuine PDQ, factory part number 639154. On a fire rated or panic rated opening that matters, since substituting non-factory latch components on a listed exit device can void the device's listing.
7) Do I need anything else besides the 639154 top latchbolt to finish the repair?
The 639154 covers the top latchbolt itself. Depending on what you find in the door, the PDQ 6300/6400 parts range also carries the vertical rods and connectors, top strikes and shims, and screwpacks, which are the items commonly replaced alongside a worn top bolt when the rod length or strike engagement is off. Pull the cover and check rod condition and strike wear before you order so you only make one trip.
8) Is the PDQ 639154 latchbolt a commercial-duty part?
It is a commercial door hardware part, intended for PDQ 6300 and 6400 Series panic exit devices on commercial openings. These are the devices used on egress doors in schools, healthcare, multi-family and institutional buildings, and the 6300/6400 parts range includes both panic rated and fire rated head chassis for replacement.
