Hi,
Our home was built in 1994, we have a few of these window cranks that seem to be stripped. They will crank the window open but they won't crank it closed, it's as if the crank is stripped when you try to close the window. We had a local window company take a look at this hardware and they think it might be "Truth" brand...? The size of the hole opening for the handle is 1/2". Do you carry these?
We also have broken levers for the locks on some of these windows. The lock unit measures 3" in length. Do you also carry these?
I forgot to mention the length of the window crank unit in the photos is 5".
