Flip Jack for trailer jack that will give you increased height when leveling a trailer. The Fastway® FLIP™ jack foot extends your trailer jack by six inches, and saves you 48 cranks in one direction. The FLIP has twice the contact surface area than other jack feet, providing more stability for your trailer. The Flip installs in seconds, with no tools needed for most applications, and fits nearly every 2-1/4" tongue jack- round or square. The Flip eliminates the need to search for rocks or wood blocks to put under your trailer jack. It is the only jack foot that is completely automatic; the Flip extends down and locks into place when jack is extended, then tucks up under the trailer frame when towing. It easily removes for low clearance situations, and fits virtually every bumper-pull trailer: horse, travel, cargo, RV, ATV, and flat bed. Works great. I replace my hand crank with a power Jack amd no long need it.
