corners

I want to mount my GPS receiver on my stern pulpit and run the wire inside the stainless 1" tubing to the lazerette. But I don't know if the corners and tees are hollow and can be used as a chase. Anyone try that before?

Aloha, I want to buy two teak 90 degree outside corners (trim) for my '79 E-35. I think the radius is about 1.5 inches (for the chart table and the sink counter edges). If you have any for sale, or know a supplier please email me at: dcapn@hotmail.com

Looking for the fiberglass corners for the rub rail. anyone know where we can get these. Got some rub rails from Pacific sea craft a few years back but no web sight now. Thanks Chuck
