Sargent 82-0399 Spindle for 94 Function Mortise Lock — 1-3/4" to 2" Door

The Sargent 82-0399 is a genuine OEM replacement spindle engineered for Sargent 8200 Series and 7800 Series mortise locks with the 94 function, designed for doors ranging from 1-3/4" to 2" in thickness. As a direct factory replacement component, the 82-0399 restores proper lever or knob actuation to the mortise lock body, ensuring reliable, smooth operation consistent with Sargent's original performance standards. Sourcing a genuine Sargent OEM spindle — rather than an aftermarket substitute — guarantees precise dimensional fit and material compatibility within the 8200 and 7800 Series hardware assemblies.

Institutional Grade Features & Benefits
