33A 35A - Von Duprin

Von Duprin HardwareVon Duprin redesigned the old 33 and 35 series a few years back.  The new series are called 33A and 35A.

The two series are identical except for the case.  The 33A series contains grooves or "ribs" in the case while the 35A series is smooth.

Product Tips Quick Tip

Check your glass door to make sure it has a metal frame at least 2" wide.

Glass Doors

Working with glass doors is difficult and expensive.  There is precious little space available to mount any hardware.

Glass DoorSome exit devices are specially made for these "narrow stile" doors.  This is the case with the 33A and 35S series.

These devices are more expensive than standard devices as all the working parts are crammed into a very small area.

The same is true with any outside trims used with the devices.  They too must mount in 2" space or less.

Remember that a metal frame holds the glass in place, so some of the metal has glass behind it.  When drilling into the frame special care must be taken to keep from drilling into the glass.

 

Comparing Series

The 33A and 35A are very similar to the 98 and 99 Von Duprin devices.
