Extra components are required to do so.
Locking bar assemblies are held together with 1/8” spring pins. Extracting these pins and
Replacing an entire locking bar assembly is simple; punch the .5” dowel pin from the pivot
point through the head casting (via a small hole in the bottom casting for this purpose),
pull out the old locking bar assembly and replace it with the new one.
If changing from fail lock to fail open or vice versa, install the dowel pin in the alternate hole.
