We have come across the operator a few times in the past. It's not made anymore, but our 39-020 and 39-021 are the only options we have that could potentially work. Now, I've never personally used them, so I can't guarantee it, but I think it's a better option than anything else we have. Just keep in mind that you'll likely have to drill new installation holes. As for knuckle clearance, that's definitely a concern. The bad news is that the handle that comes with this operator (39-274) has a 5/16" spline, which is unique. There aren't any extensions or alternate styles that we can provide. I apologize for the inconvenience. |
