This is the same part included with our halyard to cockpit assemblies. The mounting area of the base of the plate is 6.75" X 3.75" with the "wings" extending beyond these dimensions. Mounting holes may need to be drilled to match the holes in your mast step.

This part has been replaced by Pt E9051 shown below in "May we also suggest".
