The bunkends vinyl trim is securred to the fold down panel with snaps one would find on a boat top bimini or other boat applications like side curtains and so forth. They are stainless steel ( remember stainless steel is two words stain and less, they are not rust proof). The outside edge of the bunk end has the male side of the snap which is about 3/8 inch in diameter and the female side of the snap is on the vinyl bunk cover material.
The bottom of the bunk material is securred using these snaps and when traveling the bunks are held in place with straps with these snaps on the inside of bed. The exterior ones are exposed to the weather while traveling and over time the snap will get harder to put on. A little chap stick on the male side of the snap will do the trick to keep them from sticking and cut down on corrosion of the snap too.
