It's about 3" long with a screw at both top and bottom and about a 2" long opening for part of the casement window
Many of these pieces are cracked in our office building. Only the ones that are broken have slightly obstructed the closing and thus caused people to turn the cranks (Milgard 39-253) and strip the gear.
We have two problems
1. Finding replacements for the broken parts described above
and more importantly
2. Figuring how to remove the old operators and disassemble the outermost piece of the 3 piece assembly. It is held in place by a tiny retaining clip. If that can be accomplished, a remaining problem is that the replacement part obtained from Swisco does not have a place to hold a retainer clip.
