This kit is designed to replicate the original Nikon metal latch repair kit to repair the N6006, N5005 and N4004 (F-601, F-401, F-401X) broken latch. The kit includes a metal latch that is precision machined from 304 Stainless Steel and bead blasted to a satin finish. This kit also includes a stainless steel screw to affix the metal latch to the existing film door. 

The original Nikon technical memo is attached that shows the installation of the replacement latch.

I currently produce and support repair kits for a variety of Nikon film cameras. Please check my listings for other Nikon latch repair kits.
