Quick Tip

The crossbar comes long enough for a 48" wide door and may be cut down in the field for narrower doors.

When ordering devices you simply specify the series and the finish.

• 55EO x AN313 (dark bronze)
• 88EO x AN313

Fire rated versions are also available by including "F" in the model number.  (55EO-F)

Both the 55 and 88 series devices are more expensive than most of the other Von Duprin devices.  The 55 cost more than the 88 since all the working parts are confined to a very narrow space.

Variations

You may order both series with vertical rods for double doors.  The 88 series is available with both surface vertical rods (8827) and concealed vertical rods (8847).  But the 55 series is only available with concealed rods (5547).

A mortise lock version is also available using the "75" designation.  5575 for the 55 series (shown above) or 8875 for the 88 series.  The mortise lock mounts through the edge of the door using a standard mortise lock prep.  Using a mortise lock device adds another level of security to the opening as they are nearly impossible to defeat.
