PDQ 639716 – Frequently Asked Questions
1) What does PDQ part 639716 actually do on an exit device?
639716 is the bottom strike for PDQ vertical rod exit devices. It mounts at the floor or threshold and receives the bottom latchbolt coming down the vertical rod, so the door locks at the bottom of the opening as well as at the head. It fits both surface vertical rod and concealed vertical rod configurations.
2) Will the PDQ 639716 bottom strike work with a 6400 narrow stile device, or only the 6300 wide stile?
Both. The 639716 is part of PDQ's factory replacement range for 6300 Series wide stile and 6400 Series narrow stile exit devices, and it covers the vertical rod configurations in either family.
3) My PDQ bottom latch is not engaging anymore. Do I need a whole new exit device?
Usually not. A bottom latch that misses or drags is often the strike, the rod adjustment, or the latchbolt, and PDQ sells those individually: bottom strikes like 639716, plus shims, rods and connectors, latchbolts and head chassis assemblies. These are factory service parts, so an installed 6300 or 6400 device can be repaired rather than replaced.
4) Can I use the PDQ 639716 bottom strike on a rim or mortise exit device?
No. 639716 is specifically the bottom strike for vertical rod devices, which latch at the bottom of the door. Rim and mortise exit devices latch at the edge or the jamb and take a different strike, so you would need the strike listed for that configuration in the PDQ 6300 or 6400 parts range.
5) Is the 639716 the same strike for surface vertical rod and concealed vertical rod setups?
Yes, 639716 is specified as the bottom strike for both surface and concealed vertical rod PDQ devices, so you order the same part either way. The difference between those two device types is where the rod runs (exposed on the door face versus inside the stile), not what the bottom latch strikes into.
6) Is 639716 a genuine PDQ part or an aftermarket strike?
It is a genuine PDQ factory part, manufacturer part number 639716, from the replacement and conversion parts range for the 6300 and 6400 Series exit devices. If your opening is spec'd with PDQ panic hardware, this keeps the device as-specified.
7) Does the bottom strike come with mounting screws?
Screwpacks are sold as separate items in the PDQ 6300 and 6400 parts range, along with shims and drill guides for installation and adjustment. If you are installing into a new floor or threshold rather than reusing existing holes, order the screwpack and drill guide alongside the strike.
