Each mount has a degree of additional work involved in machining and is comprised from a different piece of material. The actual size of the mount may vary upon machining after material is removed to true the product. The 1/2" is not a 1/2" at the face but the base rails are approx. maintained at 1/2' as well the right angle braced corners are thicker/taller as is the same with the 4" Cradle, "our pride and Elite mount". There is nothing like it in the world. It is a premium high grade quality X-Maxx motor mount for Elite owners.
