Original request for review was upon delivery. I waited. I used the product . . . in all manner of conditions. Now that I've used and abused, it's ok to say: I am pleased. These are the real deal, delivered earlier than promised back when I got them, and doing a better (flawless) job than even I (an admitted grouch about quality) expected. They are solid, versatile, and one of those items you say to yourself "I did right getting those". Good, quality product. 116096


Tim, Ive been reading about the colored levelers, and I read that Orange are no good, yellow is the best, but are you showing Blue and saying they are far superior, and will not break... we have 28 dual axel. 7000lbs.ksocks

The leveling blocks seem very rugged and interconnect in several configurations that I think will be helpful. I rated this as 4 out of 5 only because I have not put the blocks to practical use yet. I anticipate they will work very well. 85627

  • Can Scissor Jacks be Used in Place of Blocks on a Destination Trailer
  • You can use the Ultra-Fab Ultra Scissor Jacks, # UF48-979002, in place of blocks. In fact, many newer destination trailers use multiple scissor jacks. Keep in mind, these are stabilization jacks. They are not meant to raise the trailer, just to stabilize the movement. Blocks are commonly used because they are not only inexpensive and readily available, but they also provide more ground contact and zero movement over time.
