PDQ 639153 – Frequently Asked Questions
1) What does PDQ part 639153 actually replace on an exit device?
639153 is the top latchbolt for a PDQ concealed vertical rod exit device, the bolt that throws up into the head strike at the top of the door. It is a genuine PDQ factory part for 6300 Series wide stile and 6400 Series narrow stile devices, so a worn or damaged top bolt can be swapped without pulling the whole device off the door.
2) Will the PDQ 639153 latchbolt work on a surface vertical rod device instead of a concealed one?
No. 639153 is the top latchbolt for the concealed vertical rod configuration, where the rods run inside the door. Surface vertical rod devices use their own bolt and rod parts. PDQ's replacement range covers rim, surface vertical rod, concealed vertical rod and mortise configurations separately, so order the part matched to the device type on the door.
3) My top bolt is not catching the head strike anymore. Do I need a new device or just the bolt?
Usually just the bolt. On a PDQ concealed vertical rod device the top latchbolt (part 639153) is a serviceable component, and PDQ also supplies rods and connectors, strikes and shims separately so engagement can be adjusted rather than replacing the device. If the bolt itself is worn or bent, the 639153 bolt is the repair; if it throws fully but misses, the strike and shim parts are what correct the alignment.
4) Is the PDQ 639153 latchbolt a genuine OEM part or aftermarket?
Genuine PDQ, factory part number 639153. For a fire rated or panic rated opening that matters, since using the maker's own bolt keeps the device as the manufacturer built it. PDQ supplies panic rated and fire rated head chassis as replacements in the same parts program.
5) What else might I need to order along with a PDQ top latchbolt to finish the repair?
Depending on what is worn, PDQ offers the rods and connectors that drive the bolt, head chassis assemblies, strikes and shims for engagement, screwpacks, and drill guides for installation. If you are also changing how the device behaves, PDQ makes cylinder dogging and alarm conversion kits that fit an already installed device. Check the rods and connector while the door is open, since those wear with the bolt.
6) I manage several buildings with PDQ exit devices. Can I stock one top bolt part across them?
If the devices are PDQ 6300 or 6400 Series with concealed vertical rods, 639153 is the top latchbolt for all of them, so it stocks as a single spare. Devices in rim, surface vertical rod or mortise configuration use different bolt parts, so walk the openings and note the configuration before standardizing a spares shelf.
7) Is PDQ 639153 suitable for commercial door hardware use?
It is a commercial door hardware part, supplied for PDQ exit devices used on commercial openings. It is not a residential item and has no application outside a PDQ 6300 or 6400 Series concealed vertical rod device.
