About this model

This is a very niche item. I was having a hard time finding a way to mount a strap on my Mamiya 645j, all the strap options are super expensive or fit the square lug not the slightly different round lug on the 645j. It is very similar to Hasselblad lugs. I bought these lug clips from Amazon ( and they fit the lugs but I wanted to mount some Peak Design adapters on it without them sliding back and forth. So this is my solutions, a slip fit cover with a smaller hole. See attached photos. A string is needed to thread the Peak Design attachment in, I kept the fitment tight on purpose.
