Transom cap

[NOTHING ELSE MATTERS]

You can also use vinyl siding corner piece. When i did mine, i wrapped it with glass and paint it different color so looks like a cap but fully waterproof.

Yeah when i said needs cap that means you need something on top to seal it up. i usually use 4 layers of glass over all mine.

Great idea! It looks fantastic, is waterproof, and won't corrode!

I glassed mine completly on the 18 and LOVE it. I highly reccomend it for a one time fix and clean look.
