Spreader Attachment

[rappareems]

When preparing my mast for winter storage the "mast fixture" that the spreaders are attached to slid right out of the mast when I took the spreaders off. This is a solid piece with holes drilled in it (unevenly I may add)  which the spreaders slide over to be pinned.

My old Irwin 30 spar had"ears" welded right to the mast over which you put the spreaders.  My local C 30 buddies never saw anything like this. I bought the boat yard rigged this Spring.

This seems a bit unsettling to me. Should I be alarmed?
