Thanks for posting, Brian. I think we can help. I'll go over your questions one at a time.
1) I believe your awning window is pre-1970, possibly made some time in the 1960's. 2) It's a part by part basis, to be honest. Many brand windows use a ton of different operators from all over. As for your operator, I can't get a good look at your top hole to see if it is off set like the Keller 39-061. I'm also not sure what the mounting hole spacing is. However the Keller or even the 39-025 (which has a threaded sector as opposed to using a shoulder screw) might work. Look at both operators to see if either of these could work for your window. 3) Your window is what is called an Awning window. 4) If you are planing to clean up the windows, I suggest removing the operator and then opening the window by hand to make sure nothing is hanging up in the linkage. It'd also good to lubricate the window with a silicone spray. If you lubricate the operators, use a grease type lubricant instead. |
