2" Extension, 3/8" Spline

Might you have something that would replace this?? Miami Window Corp. Pat No. 2383912 PatsPend Miami Fla

Do you have a replacement handle and extension that will fit this window crank assembly? The current handle sits too close to the granite. Thanks

good day. Having trouble finding the existing crank I have. The reason I'm replacing is because having the window open the wind moves the window back and forth rather then the window keeping still. I'm thinking the pin has worn down. Also is there such thing as a crank extension ? My existing crank ... (cont.)

I am trying to replace the handle on a jealousy window. I already ordered part 39?108. The 3/8 part fits perfectly but the T hits the side box mechanism. So I either need one that is a longer Spline I believe that's what you call it or the T part of the handle is shorter.

will an old style Pella window crank handle fit on this extension? Pella 39- 109b Thanks, Al
