Tough, Durable Inland Fender - Perfect for any trailer boat.

Keep the boat sides protected from damage caused by obstacles with Polyform Guardian Fenders. These fenders have reinforced ropeholds for durability. They have uniform wall thickness and feature molded-in ribs for extra strength and abrasion resistance.

Guardian Fenders are designed to be used in trailered boats and permanently protected moorings. Their unique valve system makes inflation quick and simple. These fenders can be hung in horizontal or vertical direction. They are available in a variety of colors and sizes.

Fendering Tip:

Hanging Fenders: Always hang fenders so they just touch the surface of the water. Tie them off on something solid and as low as possible on the boat. This prevents them from swinging in a wide arc and ending up on top of the dock.
