Retention Collar for 30mm Shaft
The PYI Shaft Retention Collar is designed to help retain the propeller or rudder shaft in your vessel in the event of catastrophic coupling failure or if the shaft comes free from the coupling.
Simple Design & Optimal Strength
The double-split design provides the maximum axial holding power with the benefit of quick and efficient assembly with the shaft installed.
Easy Installation
The design fully engages the shaft without marring. Easily installed where major disassembly would otherwise be required. Greater axial holding power than set screws or one-piece clamping collars. Effective on hard and soft shafts. It is effortless to retrofit existing prop shafts and rudder shafts. A cost-effective and quick solution that could save thousands.
