Review: Muy util - Buena calidad
Review: Good quality - Nice piece!!! I didn't realize this when I ordered it, but the 3/8" thickness is the thickness of the plate that it is designed to go thru. I had to add a backer to increase the overall thickness of my plate. Still a niece piece of machining!!
