The Von Duprin 47250398 is the OEM top cable assembly for the 33/35/98/9949 Series Concealed Vertical Cable (CVC) exit device. It covers door opening heights from 6'0" to 6'10" (up to 82"). This is the upper half of the two-cable system that runs vertically inside the door to connect the device centercase to the top latch. When the cable fails, stretches, or breaks, the top latch no longer retracts when the pushpad is operated. The door may still release at the bottom but will remain secured at the top, which is both a life safety failure and an immediate code compliance issue on any fire exit or ADA egress door.

This is a door-height-specific part. The 47250398 covers up to 82" (6'10") only. Taller doors require different cable part numbersconfirm your exact door height before ordering.

What the Von Duprin Top Cable Assembly Does in a CVC Exit Device

CVC (Concealed Vertical Cable) exit devices use a pair of flexible steel cables running inside channels within the door itself rather than rigid vertical rods mounted on the surface. This distinction matters for both aesthetics and application: CVC hardware is specified when architects or facility managers want the clean look of a surface-mounted panic device without exposed vertical hardware running along the door face, and it's the required configuration for hollow metal doors and certain aluminum stile doors where internal cable routing is feasible.

When the pushpad is depressed on a CVC device, the centercase mechanism simultaneously tensions both the top cable and the bottom cable. The top cable pulls upward on the top latch bolt mechanism, retracting it from the top frame strike. The bottom cable pulls downward on the bottom latch or floor bolt. Both latches release in the same pushpad motion, and the door swings free. The 47250398 is the top cable in this systemthe component that runs from the centercase upward to the top latch housing (part 24090110, sold separately).

Von Duprin 33 Parts and CVC Series Compatibility

The 47250398 is listed across four related Von Duprin device families:

The 33/35A Series is Von Duprin's standard Grade 1 rim panic device family available with CVC modification for multi-point latching applications. The 33A/35A designation identifies the version specifically configured for CVC use.

The 98/99 Series is Von Duprin's heavy-duty rim exit device line. The 9849/9949 designations within the 98/99 catalog are the CVC configurations, where 9849 and 9949 identify specific CVC variants with different functional and finish specifications.

All four series share the same internal cable routing geometry and centercase-to-cable interface, which is why a single top cable assembly part number covers them all within the same door height range.

Von Duprin Top Latch Assembly and Cable System: Companion Parts

The 47250398 top cable assembly is one component in the complete CVC system. The top latch assembly it connects to is the Von Duprin 24090110 (49 Series Top Latch Assembly), sold separately. The companion bottom cable for the same door height range is 47250403. For the bottom latch, the correct OEM part is 24090128 (49 Series Bottom Latch Assembly). The 49 Bottom Mounting Package (23946437) covers the hardware needed to secure the bottom latch housing to the door.

For taller door openings, the correct top cable assemblies are 47250175 (6'10" to 8'), 47250176 (8'0" to 9'2"), and 47250177 (9'2" to 10'). Von Duprin also offers a cable removal tool for the 33/35/98/99 Series that simplifies cable extraction during replacement without damaging the door channel.
