  • durable, stable and great value
Size: 1-Pack Color: Yellow
I bought 3 of them for my small camp trailer. 1 for tongue jack and 1 for each rear stabilizer. overall I am very happy with them. I was pleased to find out that they stack together nicely and even nest together a bit to save space. I like that they are bright yellow so that they are easy to see when packing up and wont get left behind anywhere. they are light weight yet extremely durable and very stable. very pleased with this purchase. ... show more

  • Helps level camper
Size: 1-Pack Color: Yellow
This block is sturdy. I can put it under the jacks of the RV to level the camper. I like having different sizes because the terrain is often not level. Yellow makes it easy to see. Happy with order.

  • Seems Heavy Duty. A Little Short For Our Needs
Size: 1-Pack Color: Yellow
This block is sturdy. Heavier than I expected, which is good. We will need two of these to be tall enough. It is a little short for our needs.

  • Stay Trailer....STAY!
Size: 1-Pack Color: Black
After a particularly stormy night I woke up and surveyed how many branches were blown out of my trees. The surprising thing was I also saw my utility trailer in the back yard instead of on the concrete pad alongside my garage. I block the tires so it wouldn't roll into the street and never thought about it rolling into the back yard. I ordered this Lanfee Trailer Jack Block instead of another tire chock. I am glad I did. It lifts the tongue of the trailer so the water more easily drains out the back and it keeps the trailer where it is supposed to be. This trailer jack block is fairly heavy so it should stay put. I also really appreciate the thoughtful drainage holes. I We have had some wind lately and the trailer has not escaped! I like it! ... show more

  • Great leveling block
Size: 1-Pack Color: Yellow
I ordered one of these for my trailer tongue jack. It’s a great little block. I had a chunk of wood that I was using and it started to crack, this block is a great replacement! It’s smaller than the wood, but still had adequate height. It’s super light weight so it doesn’t add a bunch of cargo weight. And it is a bright yellow, so it’s easy to see in all the junk in my truck! Overall, a great block for your trailer! ... show more
