Thanks for contacting us. These older hex style operators had a major problem in that the "collar" that held the handle in the operator mechanism would come loose, exactly like you describe. They don't make them like this anymore for that reason. The modern replacements, the 39-329 and 39-330, use a spline type handle like our 39-114L or 39-205. You can probably still use your existing hardware, but you'd have to either glue the handle in place or use scotch tape to sort of "pad" it out so it's not quite as loose. Personally speaking, I'd just go with the newer models so you don't have to worry about it anymore. |
