Button Style Safety Replacement Plug - Blue
[B-SRP-B]

The plug isn't as clean looking as depicted in the photo. This also takes some fitting which is not mentioned anywhere but should be in the description. The note with the plug gives 2 options to fit it. 1) use the supplied drill bit which in my case would have been too large for my pin to work. 2) put the plug in the hole and "scratch a mark then use a round file" to get proper fit. Though I have a miniature file set it definitely wasn't small enough for the task. Thankfully have a good set of punches and was able to get enough of a mark to use a cutoff wheel on my Dremel to cut a very small and shallow groove.
