Von Duprin 98EO-F Fire Rated Rim Exit Device Smooth Case Exit Only

The Von Duprin 98EO-F is a 98 series rim exit device, the latch that mounts on the face of the door and catches a strike on the frame, for single doors and pairs with a mullion. The 98 has a smooth mechanism case (the 99 is the grooved case version), and only the 98 comes in 630 satin stainless steel. This build is exit only (EO): it has no outside trim, so the door opens from the push side only. This is the fire exit hardware version (-F) for fire-rated doors. See all our rim exit devices.

What else the opening needs

Outside trim if the door must open from the outside. This exit only build has none, and Von Duprin's trim is ordered as its own part. A mullion on a pair of doors, such as a Von Duprin 9954 or KR9954 fire-labeled mullion with 499F strikes. On a wood door without SLM blocking, Von Duprin requires 425 and 825 sex nuts and bolts for the fire device.
