Von Duprin 98NL / 99NL: Night Latch Function with 990NL Pull Trim

The NL suffix identifies the night latch function. ANSI Function 03: key retracts latchbolt. The 990NL-R/V escutcheon pull trim provides a rim cylinder opening on the exterior face. Turning the key retracts the latchbolt for entry. The key is removable only when the device is in the locked/latch-engaged position. The interior panic touchbar always provides free egress at all times.

The 98 Series uses a smooth mechanism case. The 99 Series uses a grooved mechanism case. Both are mechanically and dimensionally identical. The selection between 98 and 99 is aesthetic, based on architectural preference for smooth or grooved touchbar case styling.
