Will do the job!
Pros: Built tough and will do the job I need. Zerk fittings for the wheel bearings were a pleasant surprise. Total-lock mechanism works as advertised. Thermoplastic rubber is indeed softer than polyurethane. Over-all good design. Arrived well packaged. Cons: Did not come in the color depicted. (Grey thermoplastic rubber instead of black.) The stamped metal parts have slight burrs. Would be nice to haves: Complete repairablility and parts availability. Zerk fitting for swivel head bearing.
