I am using this for our 16′ Flat Bed Trailer. Won’t have to do as much cranking with this in place. It feels to be very sturdy and shouldn’t be an issue with weight.

You can see what I was using. I bought this camper last year and of course it nickels and dimes you to death buying all the little accessories and necessities. I was putting this off since I had blocks of wood laying around, but they are a pain to drag around everywhere. Saw this one and decided to give it a shot. It is extremely well build and rated at 40K lbs. I know I’ll never even come close to that, so I feel very confident it will work for my little 6K camper. It also comes in a 4 pack if that’s what you need. Just remember, stacking these will only increase the height by 3 inches for each additional block. They have to sit inside each other for stability. Overall, very nice. Costly, but they all are and this one is 1/2 the price of the name brands. Recommend this block.

With four trailers I’m constantly hooking up and unhooking. Up until a couple years ago I kept an assortment of 4X4 and 6X6 wood blocks in the back of my truck and in the trailers. But these plastic trailer blocks are much better. Of the four I currently own this is my favorite. It’s a little smaller but that makes it lighter. I like the included rope handle. I had to add one to the other three. Being heavy-duty plastic it’s like the US Mail; “neither rain, nor snow, nor sleet, nor hail,” shall affect this block. It’s sturdy as heck and works exactly as you would expect. I recommend it.My rating system:5 stars….. Very good, recommended.4 stars….. Better than average.3 stars….. Average, nothing especially good or bad.2 stars….. Less than average, not recommended.1 star ….. Junk, do not buy.

Works great takes up much less space on the ground and is easy to move when we need to move our trailer. Light weight. Beats using a cinder block!
