I recently ordered a replacement inside handle for my storm door item #40-150 and the associated square spindle item #40-187. The spindle is too small to work in the outside part of the handle that is installed on the door. This spindle I purchased in 1/8" wide and the spindle I need is about 1/4" wide. Do you guys have a spindle that would solve my dilemma? The handle I purchased is the correct handle, but it receives this small spindle, so simple a larger spindle won't work. Any suggestions?

Thanks for posting. Can you confirm the size of the spindle you need? The 40-150 cannot accept a 1/4" spindle. The sizes it can accept are 1/8" with the spindle insert installed, and 5/16" and 3/8" without the insert installed.
