The jack lug is very robust in size, strength, and weight. My container is sitting on a gravel pad. When it was first placed, I had to dig holes under the corners to place a jack for leveling. Over the years it has settled some. I saw this jack lug and decided to try it for releveling the container. Man oh man did it save me a lot of work. There are several thousand pounds of stuff in the container and the lug had no problem at all in holding up. Just slip the lug into the container corner slot, twist it upright, and place the jack beneath it. The hydraulic jack fits perfectly in the retainer cup and away we go. Saved me hours of time and work.

This is a heavy, extremely well-made jack lug for a container van. The loop handle makes it useful when set in place. The bottle jack fits perfectly in the jack lug and makes lifting and leveling easy and quick, or rather as quickly as be managed as a 45' container can be. The jack lug makes it so much simpler to level the containers than just using a bottle jack. The jack lug can either be left in place or it can be used to only lift the container and something else can be used permanently. This jack lug is well-made & is perfect for leveling containers. I'm sure since it easily worked to level a 45 ' container then they will have no problems leveling smaller ones. I highly recommend these jack lugs, it is certainly easier than how I've done it previously.

Built to Handle the Heavy Stuff: First off, the durability is top-notch. We were confident lifting a heavy shipping container corner with this jack lug. It's reassuring to know it's built for heavy-duty tasks.
Surprisingly Easy to Use: Despite its heavy-duty construction, I was surprised at how easy it was to use. The design makes raising a container corner a smooth and efficient process.
Overall, a Must-Have Tool for Container Owners:

This is a must-have for anyone who owns a shipping container or Conex box...coupled with a bottle jack, it makes leveling them a breeze

Make sure the base of the bottle jack you are using is WIDE!!! Nothing wrong with this product, in fact, it worked very well.
