Our window cranks have been stripped over years of use. I had a window guy look at these and he figured they were from around 1991. I'm looking to make them work again. Can you help? Thanks in advance. Darren.

Hello, Darren. We have a few different operators that may match this. Start by looking at our 39-139 and 39-142. Note the difference in arm length, as well as the flat metal disc at the end of their arms. I can't see the end of your arm so I'm not certain if you have the same metal disc. That would be worth checking |
