Availability: InStock

The 91525 7" Red Poly Jumbo Keel Roller is a heavy-duty, soft polyurethane boat trailer roller designed to provide excellent keel support while helping protect the hull during launching, retrieval and transport. Its substantial jumbo profile provides a large contact area, while the 17mm centre bore suits compatible roller spindle assemblies. The non-marking red poly construction is particularly well suited to fibreglass boats where reduced marking and hull-friendly support are important.

Roller & Spindle Compatibility

The 17mm centre bore is intended for compatible boat trailer spindle assemblies. When replacing an existing roller, check the actual spindle diameter, bracket width, retaining hardware and available roller clearance.
A spindle must provide suitable running clearance within the 17mm bore so the roller can rotate freely rather than binding.

Suitable Applications

The 91525 is designed for boat trailer keel and centreline support positions, particularly where a larger-diameter roller is desirable to provide increased hull support. Red poly soft rollers are ideal for fibreglass boats.

Signs the Roller Needs Replacing

Replace the roller if it becomes deeply grooved, cracked, distorted, excessively flattened, seized or loose around the centre bore. Also inspect the spindle for bending, corrosion and wear grooves whenever replacing a keel roller.
