Review on Enhanced PowerGrip Threaded Locking by Camco 55537 by Derick Johns

Expensive but works like the original. I don't usually write reviews but thought I might help others with this 30 amp install tip. I used a heat gun (a hair dryer might work) on low heat to heat the outer raised portion of the fork that attaches to the camper. Be careful not to overheat or melt the rubber stoppers. This softens the raised outer rubber tab so that the ring can be slid on without having to heat the PowerGrip ring. When the rubber on the stopper cools, it becomes as stiff as before.
