4.5″ Red Polyurethane Flat Keel Roller – Compact, Soft, and Boat-Safe
The PRRP115X72X17 is a 4.5-inch red polyurethane keel roller with a flat/parallel design, made for fibreglass boat trailers where space is limited but support still matters. Despite its short length, it boasts a 72mm outer diameter and a soft, non-marking PU body that protects delicate hull surfaces from scuffs and pressure dents.
With a 17mm bore, this roller suits standard 16–17mm spindles and offers durable performance in tight hull-contact zones or transition areas between longer rollers.
