PDQ 639022C – Frequently Asked Questions
1) What does the PDQ 639022C part actually do on an exit device?
The 639022C is a cylinder dogging mechanism for PDQ exit devices. Cylinder dogging lets you hold the push bar depressed with a key so the latch stays retracted and the door pushes free during business hours, then re-secure it with the same key. It is sold as a replacement or conversion part, so you can add or restore cylinder dogging on an installed device rather than buying a new one.
2) Which PDQ exit devices does the 639022C cylinder dogging mechanism fit?
It is a factory part for PDQ 6300 Series wide stile and 6400 Series narrow stile exit devices, which cover rim, surface vertical rod, concealed vertical rod and mortise configurations. If the device on your door is not a PDQ 6300 or 6400, this is not the dogging kit for it.
3) Can I add cylinder dogging to a PDQ exit device that was installed without it?
Yes. The 639022C is a conversion part, and PDQ's replacement range includes kits that add cylinder dogging or an alarm to a device already hung on the door. That means the existing chassis, push bar and latch stay in place and only the dogging mechanism goes in.
4) Will cylinder dogging work on a fire rated exit device?
No. Dogging of any kind is not permitted on a fire rated exit device, because the latch must stay engaged to keep the door latched in a fire. Use the 639022C only on a panic rated (non fire rated) PDQ 6300 or 6400 device. PDQ offers both panic rated and fire rated head chassis, so confirm which one is on the opening before ordering a dogging kit.
5) Does the 639022C cylinder dogging kit include the cylinder?
The part supplied is the cylinder dogging mechanism itself, part number 639022C. Cylinder dogging works with a small format interchangeable core or mortise cylinder depending on the device, so plan on sourcing the cylinder separately keyed to your facility's system.
6) My PDQ exit device won't stay dogged anymore. Do I need a whole new device?
Usually not. If the bar no longer holds retracted when keyed, the dogging mechanism is the wear item, and the 639022C replaces just that assembly on a PDQ 6300 or 6400 device. PDQ supports these devices with individual parts, head chassis, latchbolts, rods and connectors, push bars, covers, end caps, strikes, shims and screwpacks, so a device can be serviced instead of replaced.
7) Is 639022C the actual PDQ part number I should order, and is it a genuine PDQ part?
Yes, 639022C is the PDQ manufacturer part number for the cylinder dogging mechanism, supplied as a genuine factory PDQ part rather than an aftermarket copy. Quote that number along with your device series (6300 or 6400) when ordering.
8) Is the PDQ 639022C a commercial grade part or something for residential doors?
Strictly commercial. It is a door hardware part for commercial panic exit devices, the kind used on egress doors in schools, retail, healthcare and multi-family common areas. There is no residential application for it.
