Frequently Asked Questions
What does the Blade Stop Spacer do?
The Blade Stop Spacer shims PDQ parallel arm brackets to clear a 1/2" blade stop. When a Blade Stop Spacer is used in a narrow frame application, the NFB Narrow Frame Bracket must also be used.
Which arms are for parallel arm mounting only?
PDQ lists the Extra Duty Arm, Door Saver Arm, Door Saver Hold Open Arm and Extra Duty Arm Hold Open as parallel arm (PA) applications only. The Regular Arm and Hold Open Arm can be mounted regular, top jamb or parallel arm, with a parallel arm bracket required for PA mounting.

PDQ 539008689 – Frequently Asked Questions
1) Is a back plate the same thing as a drop plate for a PDQ closer?
No. The 539008 is a back plate (BP) for the 5300 Series. PDQ lists top jamb and parallel arm drop plates as separate parts, along with parallel arm brackets, a blade stop spacer and a narrow frame bracket for special mounting conditions. If your problem is clearance at a top jamb or parallel arm application rather than a mounting surface behind the closer body, you want the drop plate or bracket, not the back plate.
2) What finishes does the PDQ 539008 5300 back plate come in, and how do I order the right part number?
Four finishes: 689 Aluminum, 693 Black, 695 Duro Bronze and 696 Gold. The finish code gets appended to the base number, so a 689 aluminum plate orders as 539008689, black as 539008693, duro bronze as 539008695 and gold as 539008696. Match the code to the closer already on the door so the plate doesn't read as a different color on the frame.
3) Do I need screws separately for the PDQ back plate?
PDQ offers matching screw packs for its mounting plates, so the fasteners are a separate line item rather than something you can assume is in the bag. PDQ also lists self drilling self tapping screws, tamper resistant screws, and sex nuts and bolts for through bolting 1-3/4 inch doors if the mounting condition calls for them.
4) I'm standardizing closer parts across a building. Can one back plate cover all my PDQ closers?
No, PDQ organizes these parts by closer series, and the 539008 back plate serves the 5300. Arms, covers and mounting plates are each listed under the series they serve across the 7100, 5100, 5300, 5500 and 3100 lines, so a multi-building stock list needs the back plate for each series present rather than one universal plate.
5) Is the PDQ 539008 back plate rated for commercial door traffic?
It is a commercial door hardware part, listed by PDQ as a replacement mounting component for its commercial 5300 Series closers. It's the same part PDQ ships on new 5300 installations, so it suits office, multi-family, school and retail openings where a 5300 closer is already in service.
