The Von Duprin 996L-NL-RV is the nightlatch-function lever trim for 98/99 Series Rim and Vertical Rod exit devices. The lever is always rigid (does not retract the latch). Instead, the key in the rim cylinder momentarily retracts the latch for entry, then the latch re-engages when the key is released.

Frequently Asked Questions
How is nightlatch different from classroom function?
Classroom (996L) uses the key to lock/unlock the lever. Nightlatch (996L-NL) keeps the lever rigid at all times; the key only momentarily retracts the latch bolt for entry.
Is the lever just decorative on a nightlatch trim?
The lever is functional in the sense that it can act as a pull, but it does not retract the latch. Entry is via the key only.
Where is nightlatch function typically used?
Offices, supply rooms, and any application where you want temporary key access without leaving the lever in a permanently unlocked state.
