Thanks for posting! I think I can help.
1. I agree, our 39-341 and 39-342 look like good matches. The best way to be certain is to compare our dimensions and pictures to yours. Stamps can be outdated or inaccurate sometimes and aren't always reliable. 2. I'm not sure how much stronger the X-Drive is over the Pro-Drive, but 8 years is a pretty standard life span for this kind of operator, to be honest, depending on use. 3. Yep, it's as easy as it seems. Just disconnect the arms from the sash and unscrew its base from the sill. It should slide right through that hole. 4. These covers are built into the operator and are not able to be replaced. You just have to use what comes with them. 5. The 39-341 and 39-142 operators can use our 39-114L or 39-205 handles. The 39-114L is a standard handle while the 39-205 is a folding handle, which seems to be what you have now. |
