The 91522 12" Red Poly Concave Roller is a heavy-duty boat trailer keel roller designed to support, centre and guide the hull during launching and retrieval. Manufactured from soft red polyurethane, it provides a durable, UV-stable and non-marking surface particularly suited to fibreglass boats. Measuring approximately 305mm wide with a 25mm centre bore, its deep concave profile helps keep the keel correctly aligned on the trailer.

Roller & Spindle Compatibility

- Check the existing spindle diameter, bracket width and retaining arrangement before replacing the roller.
Suitable Applications
- The 91522 is particularly suited to fibreglass boats, where its softer polyurethane construction provides a non-marking contact surface. The concave profile cradles the keel and helps guide the boat towards the trailer centreline during launching and retrieval.
Signs the Roller Needs Replacing
- Replace the roller when it becomes deeply grooved, cracked, distorted, excessively flattened, seized or excessively loose on the spindle. Also inspect the spindle for bending, corrosion and wear grooves whenever replacing a centre roller.
