Sleek, Quiet, and ready to ship, the new 6300 exit devices features a patent pending cush spring to quiet the device in both directions, flush end cap, nearly flush push bar when dogged, high strength chassis, and more. A major difference in the new 6300/6400 exit devices vis-a-vis the 6200/6202 exit devices is the distances between mounting holes.
The distances between the mounting holes allows the new PDQ 6300 and PDQ 6400 to be compatible with Von Duprin Exit Trims and Alarm Lock Exit Trims. So if you have a Alarm Lock ETDL27 Exit Trim or an Alarm Lock Networx ETDLN device, now you can easily put the PDQ 6300/6400 exit device instead of the Von Duprin 99 or the Marks 99. Also if you are looking to retrofit your Von Duprin V99 or Marks M99 exit device, then the PDQ 6300 exit device is a durable, high quality and affordable alternative.
