Von Duprin 99 Series Exit Devices

Choosing Von Duprin 99 Series and Compatible 98/99 Hardware

Von Duprin groups the 98 and 99 Series together as a family of heavy-duty, wide-stile push-pad exit devices. Their visible case designs differ: the 98 uses a smooth mechanism case, while the 99 uses a grooved case. This collection focuses on 99 Series devices and includes selected trim and components identified for use with the 98/99 family. When comparing products described as “Von Duprin 98/99,” check the complete model number to distinguish a finished device from compatible trim or a service part.

Start with the latching arrangement required for the door. The assortment includes 99 rim devices, 9927 surface vertical rod devices and 9947 concealed vertical rod configurations, along with selected other 99 Series models. These configurations require different door preparation and supporting hardware. For a replacement, record the existing model and compare its installation details with the proposed device. For a new opening, use the specified hardware schedule to identify the device type before selecting its length or finish.

Door dimensions and construction are essential ordering details. Compare the listed device length with the supported door-width range, and check door thickness, stile space and handing where applicable. A nominal device length is not a substitute for reviewing the installation template. Selected concealed-rod models are identified for wood door installations, so confirm the intended door material as well as the model designation. On paired doors, review how both leaves latch and which supporting components the complete opening requires.

Exterior trim determines how the door can be operated from outside. The collection includes selected thumbpiece, night-latch, dummy and lever trim configurations, but a trim listing does not necessarily include the exit device. Check the package contents and match the trim to the correct rim or mortise application and device function. Before ordering, list the device, trim and any required strike or mounting hardware separately so each component can be checked against the project requirements.

Select panic or fire exit hardware according to the requirements of the opening, and verify the listing on the exact model. For repairs, identify the existing device before choosing a cover, dogging component or conversion kit; a shared family reference does not guarantee that every part fits every configuration. Review the model-specific specifications for each selected item, including its finish and included components. Keep the existing model information available when comparing replacement hardware so the final order matches the installation being serviced.
