1. The current operators are Roto, labeled OP05-2005U on main arm. They are Pro-Drive (inset socket). Roto says the replacements are OP06-7500/01. But so far as I can tell, your 39-341/39-342 are the same. Can we be certain of this?
2. I assume the X-Drive will work better that the Pro-Drive, which strips out because the handle just doesn't stay tight (actually, it has in some windows after 8 years, but not in others). The X-Drive seems like a much stronger design. Thoughts?
3. These look fairly easy to replace -- but I'll be doing so leaning out 2nd story windows! Is it really as "easy" as removing the old one and installing the new one? Will the connectors fit exactly?
4. Roto sells metals covers for these although I haven't seen that elsewhere. I think ours have covers, although they presumably won't fit the X-Drives. Thoughts?
5. For the X-Drives, we'll obviously need handles, which you sell, although they are made by Truth. Any problems with that? Any reason you don't sell Roto handles?
Thanks very much.
