The 91542 8" Red Poly Self-Centring Roller is designed to support the hull while helping guide the boat toward the trailer centreline during launching and retrieval. With a nominal 203mm / 8" width and 21mm centre bore, its shaped self-centring profile improves hull alignment. The softer red polyurethane construction is particularly suitable for fibreglass boats, providing a gentler contact surface than hard nylon rollers.

Self-Centring Design

  • The shaped profile is designed to encourage the keel toward the centre of the roller, helping align the boat with the trailer during retrieval. This can make loading easier than using a conventional straight-profile keel roller, particularly when the boat approaches the trailer slightly off-centre.

Suitable Applications

  • The 91542 is suitable for boat trailer keel and centreline roller positions where additional assistance with hull alignment is desirable. The softer red polyurethane version is particularly appropriate for fibreglass hulls; retailers specifically describe the red polyurethane construction as the preferred option for fibreglass boats.

Signs the Roller Needs Replacing

  • Replace the roller if the polyurethane becomes cracked, split, deeply grooved, flattened or distorted, or if centre-bore wear causes excessive sideways movement or poor rotation. Check the spindle for corrosion, bending and wear grooves at the same time.
