crank handle spline fitting

A quick learner says:
My Pella has 11 teeth (spline) does the 39-227B t-handle have the same number of splines?

It is tough to figure out the proper fit for crank handles. If you need help figuring out the proper crank handle for your window crank operator, contact SWISCO with details and images so that we can research it for you. Take a look at the image attached to this post for greater detail of the inside of this Pella t-crank handle.

A home owner from Spokane Washington says:
Will these Pella window cranks work on other windows such as Alside Excalibur windows? The Crank Hand Knob 39-115 is the one I am interested in.

The 39-115 is not a replacement Pella part. You can use the replacement crank handles sold on your brand operator as long as they fit. Different manufactures use different size spline fittings. I do not know what brand of window operators Alside Excalibur windows use, but if the name 'Truth' is on it, there is a good chance the 39-115 crank handle knob will fit. You need to measure the spline on your window operator to determine which crank handles will fit.
