Ultra-Fab Products Wheel Chocks - UF21-001091

Designed for tandem-axle trailers with up to 10-1/2" wheel spacing, these wheel chocks will rid your rig of rocking by stabilizing your trailer or RV. Simply place the chocks between tandem tires and expand them until the give is gone.


Features:

  • Wheel chocks eliminate give between tandem-axle tires to prevent rocking when parked
  • Pivoting louvers on arms grip tire tread to prevent slipping
  • Included E-Z ratchet makes it simple to expand units
  • Lockable to deter theft - padlocks included
  • Heavy-gauge steel construction
  • Corrosion-resistant zinc plating


Specs:

  • Application: RVs with up to 15" wheels
  • Collapsed width:
    • Center of chock: 1"
    • Ends of chock: 5"
  • Fully extended width at ends of chock: 10-1/2"
  • Quantity: 2 wheel chocks
  • Lifetime limited warranty


Note: The purpose of the Super Grip Chock is to limit front-to-back motion on parked tandem-axle trailers. Do not use as a brake or a wheel wedge.


Eliminate the annoying rocking of your trailer or RV no matter where you park it. The Super Grip Chock braces your tandem wheels against one another, stabilizing your trailer even on uneven terrain. No more front-to-back motion.


Pivoting Louver Technology

Pivoting Louvers

The pivoting louvers allow the Super Grip Chock to get a stronger grip on your tires as they hug the surface of each tire. The raised ridges grip onto the tire tread to keep the chock from slipping. The louvers can also swivel to conform to the exact curve of your tires, creating a better grip on the tires. As a result, the Super Grip Chock is able to apply the force necessary between the tires to provide excellent stability for your trailer or RV.


Mounting the Super Grip Chock

The included E-Z ratchet makes it fast and easy to set up the Super Grip Chock. Simply place the chock, in the open position, between the tandem tires of your trailer and use the ratchet to turn the nut on the rod until the width of the unit fits the spacing of your tires. Once the chock is firmly in place, lock it with the included padlock.

Video Transcript for Ultra-Fab Products Camper Jack UF21-001091 Review

Today we're going to be taking a look at Part Number UF21-001091. These are the Ultra-Fab Super Grip Chock Wheel Stabilizers for Tandem-Axle Trailers and RVs. The wheel chocks are going to eliminate give between the tandem-axle tires to prevent rocking when parked. We're going to have the pivoting louvers on the arms. These are going to grip the tire tread to prevent slipping. They got a nice grip design and they rotate to conform to that particular area of the tire when you're tightening them in place.

That's going to include the E-Z ratchet. This is going to make it simple to expand the units. It's going to come with two padlocks. That way you can lock each one to help prevent theft of the trailer or the chocks, so it is lockable. Each one's going to have a nice, convenient carrying handle. That way it makes for easy transportation.

It makes for easy placement and easy removal. These are going to be made from a heavy-gauge steel construction with a corrosion resistant zinc plating so they're going to last a long time. They're going to stand up really well against rust and corrosion. Ultra-Fab's going to put a lifetime warranty on these products. With this part number, you're going to get two chocks. These are designed for dual-axle trailers and RVs with the wheel spacing ranging anywhere from 1" to 10-1/2".

With it fully compressed, you can see that we have a really narrow design right here in the center, so you can just take it, place it in between your tires, and then rotate it up. Then you can expand it to conform to your particular width in between your tires. Once you have it set, all you have to do is hand-tighten the tightening bolt. Once you get it snug in between your tires, to finish the tightening process, that's when you'd use the included ratchet. That's why that's provided.

These are going to conform to that particular area of the tire making sure that we get a nice grip. It's going to offer really great security, as well as stabilization. Now keep in mind the purpose of the Super Grip Chocks is to eliminate front-to-back motion on parked tandem-axle trailers. You do not want to use or rely on these as brakes or wheel wedges. Once you have it all the way tightened down, simply close the cover over the tightening bolt and then you can lock it. It's got a small hole right here. You place the padlock through, lock it in place, and that's going to help discourage theft of the trailer or wheel chock. That's going to do it for today's look at Part Number UF21-001091.

Great website makes it easy to find what your looking for, lots of info that helped me make sure I got what I wanted. Got the parts when they said I would, the wheel chocks work awesome on our 26 ft traval trailer and way sway control mounted easy with instructions, also there were some helpful videos available if needed. I will definitely check Etrailer first for anything I need from now on. 229162


Comments

Still working excellent no problems what so ever when people in the camp ground ask where to find items for their camper or truck I tell them to check out Etrailer.com

Initial impressions are that these are very solid, sturdy pieces of equipment. I installed them on my dual axle travel trailer and was happy with the stability they provided. I cannot comment on the long term durability at the moment but their construction indicates that they should last me a while. I docked them a star for two reasons, 1, the wrench that they provide with these things is a hunk of junk, and 2, the padlocks they provide are also a waste of material. The ratcheting mechanism in the wrench is prone to slippage even at low torques and I will be replacing it. The padlocks supplied don't work with the product. Simply put, the shackle is too short to reach through the padlock area and lock. Unless the equipment I received is an outlier be prepared to address these two areas. 396922

The Super Grip Wheel Chocks are the best items I have ever purchased. They are easy to install between the tandem tires and keeps the trailer from moving when hooking up or unhooking the trailer from my truck. I wish I had pictures to show how glad I am now. We purchase a new 42' foot 5th wheel trailer and put it on the spot where the other trailer sat, almost at the edge of a 45 foot drop. I now feel VERY secure that it won't go anywhere. I was a tractor trailer driver for over 44 years, so I know the importance of stationary security to keep the unit from moving. 496803

These RV stabilizers arrived lightning fast. They were the best price on the internet by far and it took me maybe 15 minutes to install them. This is the second product I've purchased from eTrailer. Since we live in our RV right now, without a doubt I'm impressed with this company and will always consider their products before others. Thanks, Steven & Christina 465071



- UF21-001091

by:


I found the Super Grip Chock Wheel Stabilizers to be exactly as advertised. These fit perfectly and stabilized my travel trailer. The locks are a nice feature. I couldnt be more pleased with my purchase and the quality of the product is more sturdy than I expected. Some of my friends have the plastic ones and I fully expect they will be upgrading to these very soon after they see the difference. I will be recommending etrailer.com for the fast shipping and great customer service! 315302



- UF21-001091

by:


The chocks work great only reason for the 4 stars is the locks that came with the chocks don't fit very well, and the wrench that was included with them slips. I Replaced the wrench with a good ratcheting open end from the local hardware store and all is good. 423242



- UF21-001091

by:


Quick and easy to use, however don't trust them solely to keep your rig from moving. Had an incident about a week ago when I was using just them to chock my toy hauler but while unloading my second MC the trailer moved backwards some and the tounge support slid off their blocks. Fortunately no one was injured and only slight damage to the tongue support. These are good but I will always use in addition to my original wheel chocks. 419691


Comments

These Ultra-fab wheel stabilizers are designed to prevent rocking of the trailer when it is parked and to deter theft. They are not intended to replace wheel chocks/wedges or brakes. We do recommend to use additional brakes or wheel wedges.

The brackets work perfectly for my dual axle trailer. Helps to keep the rocking to a minimum. The down side, the ratchet that comes with them is junk. It lasted for two trips the would not work anymore (tried to lube etc still will not work). Thank goodness that I had my tool kit with me so could get these off. The two star rating is because of the ratchet. Using my tools these work perfect. 311881


Comments

Mike, thank you for your review and your business. We are sorry to hear of any inconvenience with your ratchet and have forwarded your review to our customer service team to see if we can resolve this for you.

So far they have been okay. However, the rachet tool kinda stinks for tightening it down. It doesn't stay in postion so I have to hold it over while tightening it down, otherwise it slips and barks your knuckles. Also, I have one that has gotten cross threaded and isn't working anymore. So, okay for the price is about all I can say. 521446

Looking for something to secure my 24' travel trailer. I had inexpensive plastic block type wheel chocks that just didn't work the way I wanted them to. These secure the trailer, steady movement previously present with ground chocks, just elevates the sense of security when parked on any slope. Handy rachet included is a bonus. 430527

Use these on every trip out with the travel trailer. Even got a bigger trailer last spring!

I took them out of the box and installed them on my trailer. They seem to do what they are supposed to do, and the price was reasonable. I chose Ultra-Fab over other brands because of my positive experience with Ultra-Fab products. The chocks arrived in three days with E-Trailer's free shipping. Great service. 310501

One year later, they still do what they are supposed to do. Thanks Ultra-Fab and ETrailer!

These made a big difference, even with a stabalizer system. People ask me how my RV is so stable, and this is definately one of the reasons. Great sales experience from etrailer. Love the web page, and all the information and videos. Gives me a lot of confidence that I'm getting the right product the first time. 398893



- UF21-001091

by:


Only reason for 4 star instead of 5 is because like everyone else I feel that the wrench included is almost worthless. It is nice they include it but either include a better one and raise the price or remove it and lower the price so I can have more money to buy the ratchet wrench I am going to end up using. 433910

I have been purchasing items for some time now, from my new 5th wheel hitch to small items such wheel chocks and plug adapters. I have NEVER been disappointed, all orders arrived on time, packeged securly, and work as avertised. I most certainly will be a coustimer as long as I own ay type on trailer. 505824



- UF21-001091

by:


These chocks work great and definitely do the job. Once installed keep in mind that you should check them in an hour or so if tires are hot when installed. Tire's will shrink when cooled causing a loose fit. I have used them for a year now and wouldn't go without them. Awesome service from etrailer too! 320484

Very good Gripping Wheel Chocks, work as described in the purchasing documentation. A little stiff to open and close but I use a battery powered drill with a socket mounted to open, close and adjust which makes the operation very fast and easy. The trailer does not move once these Chocks are mounted. 519160

by:


The Super Grip Chocks work very well on my 25' Shadow Cruiser as a final step to stabilize the unit against sway & motion while step up on the campground. Instructions are clear and installation/removal easy, just remember to install them before the slides go out! I'd buy again from ETrailer!! 493963



- UF21-001091

by:


Just got these. I ordered them for my son to use on his trailer. So we won't know how good they actually work until spring when we can take it out. (That's why I only gave it a four star now). They are well built and will work great as I have a pair that I use on my trailer. 325539

These things do what they say there going to do, definitely help stabilize my travel trailer. I also like that it gives a thief something else to have to deal with... the locks are cheapies, yet keyed differently??? Really like the stabilizers/chocks, would recommend. 341978

Had problems getting my first order but etrailer got me a new order on the way and everything is good. Product description is a little off these are very tight to squeeze into 2 inches let alone 1 as decribed but I got them to work and all is good, Thank You George 406773

They work just fine, although they are very tough to install but they do work

These tighten fine, but when loosening them, the nut does not open the chalks, it requires some pushing and pulling to get them to budge. It would be an easy design to fix this issue, a washer or c-clip below the retainer would make the chalks open correctly. 475052

The wheel chocks work great. Easy to install and use. We noticed a change in RV stability immediately. Installed on a 2013 Montana 37' fiver. This is a good product, good design and shipped quickly for the best price on the internet. Thanks. Happy travels. 330092

Jacks are easy to install and remove although a little difficult to get centered correctly between tandem wheels. I am a little disappointed in experiencing some movement in trailer yet when jacks are installed despite experimenting with tension on tires. 423919


Comments

Ron,Thank you for your review. The wheel stabilizers are only designed to keep the trailer from rocking while parked and to deter theft. They are not intended to take the place of wheel chocks/wedges or brakes for the wheels. Although these wheel stabilizers work well for what they are designed for, we always recommend to still use additional wheel chocks to keep the trailer from rolling.

The scissor Jacks have worked without a glitch and I have no issues with rachet wrench. I bought the twin pack which brought two locks. However, the locks did not have matching keys. So I bought a set of matching key locks at the hardware store. 454901

The stabilizers are just as described. They fit between the tires exactly they should. The shipping was incredibly fast! I was very pleased with how quickly it was received. Will use etrailer.com again for our camper needs. 323061

Comments

Again, another fantastic product. My trailer has 16 wheels and G rated tires. Not a whole lot of room in between the tires to slide a chock in between and this is the only one Ive found that folds flat enough to get between the tires and stabilize the camper. And folding as flat as they do, they stow easily as well.*
