Our gears are stamped steel rather than pot metal, so they won't strip out like the old ones.
Our operators have a 1/4" diameter hole in the tip of the arm to accommodate the optional Hehr nylon friction pads which were used on many windows in the 1950s and 1960s. This minor detail will make your restoration much easier.
And to top it all off, we include a quality two-piece spinning handle rather than a cheaper one-piece fixed handle.
TIP: If your window requires this style operator but with a shorter arm, you can cut the arm to length and re-drill the hole.
