98 and 99 - Von Duprin Devices

Von Duprin's 98 and 99 series devices are nearly identical.  The only difference is cosmetic.

The 99 series is the most popular and has grooves in the case.

The 98 series has a smooth case.

Beyond the case, all other features of the two series are identical, including the price.  One reason the 99 series is more popular is that scratches and nicks are less apparent on a grooved case.

Device Length

Device length is specified when ordering (99EO x 36).  The standard length is "36", even though the device itself is shorter than than.  When a "36" length is specified, it is really saying the device fits a standard 36" door.

The other length available is 48".  It fits doors up to 48" wide, but may also be cut down in the field for narrower doors.  Roughly 5" may be cut from either device length.

Device Finishes

Device finishes include popular architectural finishes that are plated.  They also include special aluminum finishes of US28 for clear aluminum and AN313 for dark bronze anodized aluminum.

Plated finishes are more expensive since they are applied to a steel base metal and the finish process is more expensive.

Aluminum finishes cost less.

Ordering Examples:
  99EO x US28
  99EO x US3

Fire Ratings

Fire rated doors require fire-rated hardware.  Exit devices are available both non-rated and rated.  Fire-rated devices are more expensive, so make sure they are required before ordering.

Von Duprin models that contain an "F" in the model are fire rated.

• 99EO - not rated
• 99EO-F - fire rated

Quick Tip

Doors exiting to the outside are not fire-rated.

Outside Trims

The one area that trips people up more than any other is Outside Trims.

If you think of a Trim as a Bolt-On Accessory you'll be ahead of the game.  Take the example of a door that has just a device mounted to the inside.  As some point, a lever needs to be added to the outside.  It's simply a matter of ordering the trim and bolting on the accessory.

A few years later the lever needs to be replaced, but this time a knob is wanted on the outside.  Here again, you simply un-bolt the lever and bolt on the knob.

Example Outside Tims
Image	Notes
	990TP - Thumbpiece Pull When ordered with device - 99TP x 36" x US28
	996L-DT - Dummy Trim When ordered with device - 99L-DT x 36" x US28
	996L - Lever Trim When ordered with device - 99L x 36" x US28

When ordering an exit device by itself the designation is "EO", exit only.  No entry is allowed from the outside as there is no outside trim.

But if you want the device to come with a lever outside trim, you add "L" to the model number.

• 99EO - No outside trim, exit only
• 99L - Lever outside trim is furnished with the device

Quick Tip

Locking trims use keyed cylinders.  Cylinders are always sold separately.
