Removing PELLA SLIM SHADE KNOB FOR CASEMENT OPERATOR

Hi there!

Was so happy to come across your website while searching for help figuring out how to get the little crank knobs off my 80's Pella windows so I can open the metal clips and remove the interior panes of glass to clean them (i.e remove small dead spiders....lol) and in some cases repair the blinds between the 2 pieces of glass. I see that I can buy replacement knobs but I can't get the original ones off. Have tried twisting in both directions and then gently prying but I am afraid to break the glass by prying too hard. I'm sure there is a trick but I can't figure it out and of course b/c these windows are possibly 30 years old there are no Pella manuals available online. Called the Pella retail shop but they had no clue what I was talking about.

Hoping you guys might know how to get these knobs off! If not thank you anyway in advance for reading my inquiry!

Best regards,
Adrienne

Hi!  I found this thread as we have the exact Pella problem - how to remove the crank knob that turns the slim blinds so that we can remove the glass panel and clean the glass on the inside.  Does it just pop off if pried or is there another trick?  Trying not to break anything as these were installed in '94!  Many thanks for any thoughts,
Marian
