Description
The Von Duprin 991K-M is a knob trim for 98/99 series mortise exit devices, designed for facilities requiring key-controlled egress hardware. This trim allows authorized personnel to lock and unlock the knob independently, making it ideal for high-security applications, healthcare settings, and institutional buildings where controlled access is critical.
This trim is compatible exclusively with Von Duprin 98 and 99 series mortise devices. Installation requires professional fitting to your existing mortise lock body; our authorized dealer experts at E.D. Locks can guide you through compatibility verification and setup.
