Adjustable Height for Leveling: The Kohree RV leveling block set features 10 blue pieces (consisting of 6 stackable upper blocks and 4 flat lower blocks). Arrange them in a pyramid configuration to achieve the height you need for leveling.
Special Design: The slope design of the top block helps your camper wheels move easily from the ground to the leveling blocks. The flat-bottom design means you don't have to pound or dig dirt out of them after use.
[Heavy Duty Construction] Built with a high-performance polymer. To meet the load-bearing needs of the trailer, we have upgraded the internal structure. It is extreme and sturdy—up to 15,000 lbs. The professional block designed for motorhomes and trailers is much better than wood blocks or other blocks.
[Upgraded Design] The top of the block is designed with grooves to enhance stability during stacking use. Side hole design for easy carrying.
[Perfect Size] About 6.3" Tall. Bottom Size: 11.2"x 8.85". Stack according to the required height. Top accommodates 9" round 5th wheels jack foot.
