Best for: one-piece protection on a single corner with a larger radius inside curve. This corner cap is designed for heavy-duty protection and is compatible with many pontoon configurations that use 90-degree rounded corners. A caution is to verify compatibility with your specific pontoon model, as some Starcraft or Monark lines may differ in corner sizing.

Best for: complete corner protection on both ends of a pontoon, ideal for boats with active docking or higher risk of impact. The four-piece kit provides flexibility in coverage and a cohesive appearance.

Best for: docking safety on aluminum decks, offering cushioned protection with flexible PVC that blends with the deck’s appearance. It includes stainless fasteners for secure attachment. Choose this if you want a high-visibility, flexible bumper that protects both radius and 90-degree corners, though it may be bulkier than cap-only solutions.

- PVC fenders provide flexible cushioning, useful for frequently docking or close-quarters maneuvers.
Which size is right for my corner?
