Video Transcript for Review of Weigh Safe Camper Jacks - Flap Jack Folding RV Stabilizing Block Qty 1 - WS63ER

Hi everybody. Andy here with etrailer.com. Let's take a real quick look together at this Weigh Safe Flap Jack RV Stabilizing Block. Now this durable jack block is going to give you a stable base for your trailer, RV, or camper, making setup very quick, and easy and hassle-free. Now we do offer different quantities of sets of these blocks depending on what you're looking for. So on your screen, I'm putting the model number up there based on the quantity that you're looking for.

So we do provide this in a set of four, a set of two, and then just this individual one. So whichever one's gonna work best for you, you can just take that model number, pop it into the search field of our website, and that will take you to that quantity that you are looking for. But everything that we talk about with this one's gonna be the same for the set of two, and the set of four. So this flap jack block is going to collapse down like a pancake. And it's going to take up minimal space when this is not in use, which is great.

So as you can see, this is going to fold down slim and flat, and you're not going to have to worry about struggling to store this like you may with more traditional, bulky jack supports. So it's no complicated assembly required. So lemme go ahead and put it back together again. You're just gonna separate these three pieces. And so as you can see, on the top and on the base, which obviously these parts are interchangeable.

We do have very strong magnets here at the center that's going to snap everything into place. So I'm gonna use that as my base. I'm gonna take the center section here, and unfold it. And then I'm just going to lock this into place in the base here. Find that connection point here.

There we go. And then, just like that. So that's how simple this is going to be to put this together. Just a matter of seconds. This is a tool free solution that's gonna get you stabilized in no time. So this has a weight capacity of 6,000 pounds. So it's gonna be 6,000 pounds per block. And each jack block is built to handle heavy loads without flexing. And the solid design is gonna give you a steady, reliable lift, reducing stress on your jack and equipment. As you can see, those magnets are holding pretty good. So, really gonna hold well together. Lemme get my ruler here and give you some overall measurements. Looking at the over overall height, we're sitting pretty close to eight inches tall. And then the overall length, lining that up there at the longest point, about nine and a half inches long. The overall width, pretty close to eight and three eights inches wide. And so when you have this folded, so again, the overall height when this is put together is gonna be right at eight inches. So then when you have this folded back into the flap jack mode, line up my notches here. We're sitting right at two inches. So that's how, how much it collapses. So again, very thin, very portable. So this is designed with campers and travelers in mind. And this is lightweight, compact. And then it comes with this really great case here. And so I wanted to show you, this is designed just for one flap jack, and then depending on the quantity that you get, the case obviously will be bigger. So I'm just going to slide this in just like that. And then zip the top panel shut. And that's how simple this is going to be. This is kind of like a, a nylon covering or surface. Exterior is the word I'm looking for. So that's gonna keep the flap jack safe and secure, and in good condition. It's not gonna get dirty or anything like that, and then it's gonna be ready to go. So if you are hitting the road and you're looking for an easy, quick way to set up some blocks at the campsite, this is really gonna be a great item for you to consider. If you do decide to pick this one up, or maybe the set of two, or the set of four, we would love to hear back from you regarding your experience using these blocks. And you can do that by dropping a comment, or a review on this product page. And if you leave a review, you can also send us photos as well. So we would love to see these in action with your setup. But either way, we'd love to hear back from ya. Well, that's gonna wrap up our look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me.

Product is great, but the delivery driver left the package on the bottom step and it was raining only about three more steps and it would have been on the porch not out in the rain.



by:

Thanks Etrailer for fast shipping and delivery, little bit of a puzzle to setup at first but got the hang of it pretty quick. Heading out this weekend so will try them out, looks to be high quality product.

This is something that I was needing for a long time. I don’t have the space for the Anderson jack blocks and I had to carry wood blocks in the back of my truck for my trailer. Now I can store them in the trailer. They are very easy to set up and use.



by:

We are amazed how compact and light this item is - especially when compared with our previous tongue block. It appears to be very well-constructed and sturdy, although we have not yet had the opportunity to test it with our travel trailer.

They work great. No space used hardly when storing easy setup. Best jack block I’ve seen yet

See what our Experts say about this Weigh Safe Camper Jacks

  • Does Weigh Safe Flap Jack Have Enough Capacity For 2019 Grand Design Momentum 397TH?
    Hey there Nate, yes, the Weigh Safe Flap Jack Folding RV Stabilizing Block - 8" Tall - 6K # WS63ER will work great for your 2019 Grand Design Momentum 397TH that you say weighs 20,000lbs. The tongue weight / pin weight according to my sources should be around 3,500-45,00lbs at most. Each block is rated to 6k, and you'll actually have 2 up front sharing that weight, so you'll be fine there. Then the landing gear jacks only help to level and stabilize the RV, and you won't be anywhere close...

  • Can Flap Jack Stabilizing Jack Be Used On Trailer Tongue Jacks, RV Leveling Jacks, And Scissor Jack?
    Hello Layne, great question. The Weigh Safe Flap Jack Folding RV Stabilizing Block - 8" Tall - 6K # WS63ER will work for all of what you asked about - trailer tongue jacks, leveling jacks, scissor jacks. As long as your jack foot fits in the Flap Jack's surface area of 9-1/2" by 8-3/8", you'll be fine! Also make sure you aren't putting more than 6,000lbs on it. I doubt you'd go over since this is such a high capacity. These are available in quantity of 1 # WS63ER , 2 # WS78ER, and 4 # WS88ER.

  • Is Weigh Safe Flap Jack Folding RV Stabilizing Blocks Safe For Long Term Use, Or Only Short Term?
    Hey there Leighanne, that's a great question. Luckily, the Weigh Safe Flap Jack Folding RV Stabilizing Block # WS63ER does not have any stipulations as far as long term storage goes. They hold up well in the weather and elements, and have a weight rating of 6,000lbs which is enough for most heavy 5th wheels, campers, and trailers etc. These are also available in 2 packs # WS78ER and 4 packs # WS88ER .

  • What Is The Difference Between Weigh Safe Flap Jack Blocks WS48ER And WS63ER?
    Good morning Jess. The Weigh Safe Flap Jack Folding RV Stabilizing Block - 8" Tall - 6k # WS63ER is just the jack block itself, whereas the Weigh Safe Flap Jack Collapsible Trailer Jack Support and Shoe Scraper w/ Storage Bag # WS48ER is the jack along with a shoe scraper # WS98ER to keep the entry way of your camper/RV clean. Both kits come with carrying bags and are rated for 6,000lbs.
