Save the grief of using blocks and be able to extend your tongue jack automatically that also has a great footpad with the use of a
Fastway® Flip™ Automatic Jack Foot
Most trailer owners spend a lot of time hassling with their tongue jack chasing around several wood blocks, kneeling down and messing with a pin and putting up with a flimsy aggravating removable jack foot.
I use the Fastway Automatic Jack Foot which adds up to 6" to the tongue jack and it's unique folding action makes lowering and raising of the jack quick, easy and secure. Hassle free and all self contained. I'm totally impressed with it! Check them out!
