There are a few models here that are close to this. But this model fits all 4 of my large tape measures (the kind that are about 3.5" wide and 25ft or so long). One #6 countersunk screw. Don't over tighten the screw or it will crack.
Just watch check the belt clip before using it. One had a screw almost out and this pulled it out, stripping a few threads.
The author marked this model as their own original creation.
