Spindle too wide
I ordered this item a couple, of months ago. It turned out to be too large for the hole in the assembly. I wrote a review of that fact and recycled the spindle. I decided to try it again since I could not find a 3’’ spindle anywhere else. I planned to grind the surface enough to fit. it turned out that the threads wouldn’t fit either (by less than a millimeter. I don’t want a refund; I just want a spindle that will fit. When ordering, I did not see an option for a particular “size.” I see in this review request was actually a “wide size.” Do you have a 3’’ spindle that is not ““wide size?”
3" Long SpindleJK12/27/2024Jeff K.United States
doorknob spindle doesn’t fit
The 3” length is fine. The width of the spindle is about .5mm too large to fit through the opening in the assembly. Cannot use the spindle.
