Name/Find this part - Corner guards under back to back lounge

[tech_dog]

I'm redoing my Tournament 192's back to back lounge seats and I'm looking to replace the nylon corner guards that go around and under each corner. The originals are stamped "Wise" but I can't find them for sale and Wise hasn't gotten back to me.

Does anyone know what these are called and where I can find them, or anything reasonably similar and marine grade? They're about 2-1/2 x 3-3/4.



Thanks,

T
