NovelBee 4 Pack of 316 Stainless Steel Rub Strake,Polished Line Rub Strakes for Marine Boat Yacht RV (Length:8 Inch)

I used this style years ago, so I know how they work on a rounded surface.. out of all of the other offerings, these were the only ones I found to be concave.. all others were solid material and flat on the back side.. this made them want to teeter on a rounded surface.. it is difficult to see that they are concave, but they are.. the similar ones I used years ago lasted for 20 years or so.. do be careful of the edges.. as you mock up their location they can lightly scratch gel coat..

2 of the 4 i ordered are bowed in the middle and it doesn't say 316 stainless steel on any of them. Made very cheap.
