PDQ 584689 – Frequently Asked Questions
1) What does the PDQ 584 latch protector do, and where does it mount?
The PDQ 584 is a 12 inch interlock latch protector, a steel plate that covers the gap at the latch edge of an outswing commercial door so a pry bar or shim cannot reach the latchbolt. The interlock style wraps the door edge and engages the frame when the door is closed, which is what blocks jamb spreading and loiding attacks on the latch area. It is a commercial door hardware accessory, not a lock, so it installs over an existing latch or exit device latch without changing the lock function.
2) Should I use an interlock latch protector or a flat latch guard on an outswing door?
Pick by the threat and the gap. A flat plate, like PDQ's 3-3/8 inch notched round latch protector, simply shields the latch from a pry tool. The 584 interlock version adds a lip that engages the frame, so it also resists the door being pulled or the frame spread to disengage the latch. On an outswing exterior door where the latch edge is exposed from outside, the 12 inch interlock gives more coverage along the latch area. For an inswing door the latch edge is already protected and a guard is usually unnecessary.
3) What finishes does the PDQ 584 latch protector come in, and how do I order the right one?
Two finishes: 689 aluminum and 695 duro bronze. The finish code becomes part of the part number, so you order 584689 for aluminum or 584695 for duro bronze. Aluminum suits openings with aluminum storefront or painted hollow metal frames; duro bronze is the darker option that blends with bronze or dark anodized doors.
4) Will the PDQ 584 work on a door with a rim exit device?
Yes, that is the common application. The 584 is a 12 inch protector covering the latch area at the door edge, so it shields the rim latch and strike region of an exit device on an outswing door. It does not interfere with the device itself since it mounts on the door edge area rather than over the push rail. Confirm the mounting holes clear the device case and strike before drilling.
5) Is the PDQ 584 latch protector rated for commercial traffic or is it a residential part?
It is a commercial product, part of PDQ's general hardware line of accessories that complete a commercial door opening. That makes it appropriate for multi-family entries, schools, retail back doors and other openings where the latch edge of an outswing door is exposed.
6) What is the manufacturer part number for the PDQ 12 inch interlock latch protector?
The base PDQ part number is 584. Finish is appended, giving 584689 in aluminum and 584695 in duro bronze. Use the full six digit number when ordering so the right finish ships.
7) I need to standardize latch guards and door stops across a building. Does PDQ cover both?
Yes. The same PDQ general hardware line that includes the 584 interlock latch protector also covers wall stops in convex, concave and adhesive bumper styles, floor stops in low dome, high dome, riser and offset versions, kick down stops in 4 inch and 5 inch lengths, a 5 inch hinge stop, roller stops, roller latches with T, ASA, full lip or angle stop strikes, ball catches, door silencers, coat and wardrobe hooks, a 160 degree door viewer and a dust proof strike. Finishes offered vary by model, so match codes model by model when you spec a whole building.
