Excellent service and fast shipping. Will definitely use again!!



Working great. Exceeded my expectations.


I bought these wheel chocks so when I take my lawnmower to be serviced I don't have to worry about it rolling in the back of my SUV and braking out the back window. I received them in time to take and retrieve my lawnmower. It worked great just like I was hoping it would. 1 thing I would do different is buy another set, for the front.



Unfortunately my lawnmower died and I had to get a new one and the wheels are wider and dont fit in the slot. The other one was perfect, no movement front or back.


Excellent. Used it to block the tires of my car trailer.


They work great on my 30" riding lawn mower when I use a trailer to take the mower in for servicing!


Strong but light. Pack well as they nest within each other. Fit my 13" wheels perfectly. Good value.

Dean E.


Chocks are still serving well, even better after I added non-slip tread to the upper chock surface.


Products received as promised. All quality parts and made in USA on most items. Saved on shipping and great tracking of products as they arrived here in Tampa Fl. Talked with staff about other items I plan to order very helpful. Could not be more pleased with products or service. Mirrors fit perfectly on 2016 Ford F 150 snap in place securely and come with nice storage bag. The curt trailer hitch is a solid build with a perfect weld and beautiful power coat finish. Wheel chocks are stackable, appear durable and light weight. The friction control sway bar looks well made but not installed yet but comes with a 10 year warranty. All in all great products, at a reasonable price! Best I could find on the net and saved compared to buying on other sites or locally.


I bought these to bolt to my flat bed trailer deck that I use to carry my race car. They have the nice feature of each having 2 bolt holes and molded lands for this purpose. The only less-than-perfect feature is the radius of curvature is much smaller than the car's tires.


This was not a good buy. They are plastic and I have a large trailer. They seem to slide all the time. I only used them once. I need to go to the rubber ones. They have more gripping power


I received these tire chocks yesterday, and just checked to see how well they fit under our TT (it has 205/75-R14 tires, but these will definitely work on larger tires equally well) since it's stored behind our house on a gravel pad. They're sufficiently strong and effectively shaped for proper placement, and will definitely work satisfactorily to secure our trailer when it's parked at campsites. I've been using small 2x4 wood blocks since last year when the TT unexpectedly rolled backward almost 2 feet while I was getting it ready to hitch up for the return trip home. I was astounded to seen it moving slowly to the left just inches in front of my eyes after just having raised one of the front jacks - albeit not nearly as much as my wife who was inside getting things secured! :-O Also, these are light weight and "nest" inside each other, so they're really convenient to stow even when space is limited.


This is my 2nd time ordering from etrailer. Both experiences have been fantastic. My orders have arrived sooner than expected and the quality of the products have met or exceeded my expectations and the prices have been always been lower than the competition. The FloTool Wheel Chocks look to be well made and sturdier than my current chicks. Thanks etrailer - GREAT JOB!!


The plastic in these wheel chocks is not pliable or flemsy, but more like rigid. They are designed with bends and ribs that reinforce the sides and bottom. I added a 4' poly rope & tied a bowline knot on each of the pair of chocks. There is a strong reinforced hole made into the plastic that is recessed at the bottom & side where the tire rests against the plastic incline. My cord and the knots will be close to the tire on both sides where the tire is on the ground. I probably won't see my bowline knots, my cord will come out on both sides where the tire hits the ground. TY. Sincerely ...


Great service,
One of the major items
was going to delay my order, etrailer caught it and emailed an alternate selection that matched exactly. I also noticed one of the adaptors was universal not vehicle specific, they easily canceled the order with no charge. I reordered and it was shipped the same day! Everything was well packed and undamaged on arrival, standard shipping in less than a week!


The wheel chocks are what I need for a small light trailer. They nest to save space and they are light weight. The pin and clip fit the hitch I purchased last month. The price was right.


My first order a month ago was shipped promptly and the products, a brake controller and towing mirrors, were high quality. This prompted my second order, which arrived again promptly with excellent products. I seldom answer review requests, but this company deserved every bit of a five star rating.


Be aware these are lightweight. That is good if you want less weight to move around but it is a comprise for durability. They don’t cost much that’s a bonus on less you have to replace them. Light duty go for it. Anything moderately heavy spend the $ for better wheel chocks.


Great prices on the products I was looking for...easy ordering and fast shipping!

Amy M.


The products are just as good as when I got them! Appreciate the follow up.


Everything was delivered on time and the prices are great. I highly recommend your store for anybody looking for trailer hitches and accessories. Thanks


We always order from because they have proven to supply excellent products that are accurately described so we get the right thing every time. Prices are fair, shipping is super-prompt, and they are very helpful when needed. Thank you for always performing!


Works as expected/intended. Stack together nicely. Only complaint is that they can get wedged under the tire and can't pull it out without moving the trailer, but they do their job of keeping the trailer from moving.


Wheel chocks do what they are intended to do, holding my pop up camper in place while lowering the scissor Jacks. Thanks Etrailer.


Ordered the wheel chocks and Master hitch lock. The items were quality items and fast shipping. Second order from etrailer and will do again.


I have not yet tried the products. But compare to other products they seem to be a better built product. The grooved bottom is something I was looking for since I camp in sites with plenty of gravel. Leslie C was great, very professional, gave us a good feeling about doing business with etrailer. Shipping was great and received the product in ample time. Thank you.


The best feature these chocks have to offer is that they NEST when not in use. They take up a tiny fraction of the room in your kit, compared to non-nesting wheel chocks. Still, they appear sturdy and should prove effective at keeping my trailer stable.


Great little light weight stacking chocks. Used them for our pop up. Weighs about 2k lbs. Used these under one wheel only as the leveler was always under the other wheel.


came fast and packaged very well. my last purchace was model specific clip on mirror extensions. they fit like a glove.i am sure i will be just as happy with the recently purchased products!

  • Can Trailer Breakaway Switch be Used as Parking Brake
    I do not recommend using a breakaway switch like the Hopkins Engager # 20099 that you referenced as a parking brake to hold the trailer in place. When pulling the pin out of the switch full 12V power will be sent to the trailer brakes and it won't release them until the pin is re-inserted or the battery dies. Locking the brakes up like this for longer periods of time may actually cause damage to the assemblies themselves. A better option to keep your trailer in place when it's parked...

  • Can FloTool Wheel Chocks Fit 235/80-16 Size Trailer Tires
    I reached out to my contact at FloTool and the # FT11930MI wheel chocks are only rated for wheels that are 20 inches in overall diameter. They're designed for lawnmowers and golf carts and not trailers. Instead I recommend the etrailer wheel chocks, part # 288-02011-2, which can be used with your 235/80R16 tires. I linked a video you can check out as well.

  • Can FloTool RhinoRamps be Used With Jacks?
    The FloTool RhinoRamps # FT11909MI can be used to raise your vehicle and work under it but should not be used along with jacks. If you use the ramps to lift the front, for example, you would need to keep the rear wheels on the ground and use wheel chocks such as # FT11930MI to secure those wheels. I've added links to video reviews of both products for you to take a look at.

  • Will Ultra-Fab Stackable Stabilizers # UF48-979003 Work to Steady a Trailer During Unloading
    The Ultra-Fab Stackable Stabilizers for Small Trailers and Campers # UF48-979003 are a perfect item to stabilize the rear of your toy hauler or other trailer while you're unloading your motorcycles. This pair of stabilizers has a total weight capacity of 12,000-lbs and features no-rust die-cast aluminum construction. If your trailer has a tongue jack with a caster wheel you'll want to immobilize it to prevent unexpected movement of the trailer nose while you're moving its contents around....

  • Recommended Wheel Chocks For Enclosed 7-ft x 14-ft Tandem Trailer
    To hold your trailer in place when parked and prevent it from moving I recommend the FloTool Wheel Chocks, part # FT11930MI. These wheel chocks will work with wheels up to 20 inch diameter and they measure 8-1/8-inches long x 6-inches wide x 4-5/8-inches tall. There are 2 chocks in the package so you may want to adjust the quantity when ordering for your tandem trailer.

  • Can FloTool Wheel Chocks # FT11930MI be Used to Secure a Riding Mower or Push Mower in a Truck Bed
    The only chocks that would do a decent job of keeping a mower in place in a truck bed would be ones that are permanently mounted to the truck; preferably to the frame and not just through the bed. FloTool Wheel Chocks # FT11930MI could be permanently mounted by running some screws down through the holes that are in the chocks but then you have to rely on the strength of the screws to hold the weight of the mower. For your application straps should be the primary means of restraint while...

  • Does 2021 Kia Seltos Needed to be Lift on Jacks to Install Trailer Hitch Receiver
    It is not necessary to have your 2021 Kia Seltos up on a lift or jack to install the Curt Trailer Hitch Receiver # C65FR. It may be slightly easier given you'll have more room if you were to use something like the FloTool RhinoRamps Max Vehicle Ramp Set # FT11912MI and Wheel Chocks # FT11930MI but it is not necessary for the installation. I have added a link to the installation instructions for you to check out as well of the Curt Trailer Hitch Receiver # C65FR.

  • How Many Wheel Chocks Should be Used
    We recommend using 2 of the Ultra-Fab Chock and Lock Wheel Stabilizer # UF21-001060 when your trailer is parked as that will keep it more stable on both sides. You can find a kit of 2 with part # UF21-001070. Please note that you also need to add the chocks like the FloTool Wheel Chocks # FT11930MI on the outsides of your trailer tires to limit the movement of your trailer.

  • Wheel Chock to Keep Trailer From Rolling
    The Club Tire Claw XL Wheel Lock # WI491KA-491LNP is for security and while it technically can stop your wheels from rotating it is not meant to stabilize a trailer to keep it from moving. What you would want instead is a wheel chock such as FloTool Wheel Chocks for Trailers and Vehicles Up to 20" Wheels # FT11930MI or the Valterra Heavy Duty Wheel Chock # A10-0914. I've added a link to our page with our selection of wheel chocks for you to take a look at.

  • Using Wheel Chocks on 2011 Airstream Sport 22 Foot Trailer
    When using traditional wheel chocks like the FloTool # FT11930MI, I recommend using them on both sides of the trailer. This will be the safest option, especially if you park on a slight grade. Using wheel chocks on both sides of the trailer will also help to further stabilize it when at a camp. The method you mentioned in your question will do a nice job of wedging the chocks into place on your trailer tires. As long as they are set to prevent unexpected movement on the Airstream, they...

  • Where to Place Jacks When Installing a Trailer Hitch on a 2019 Dodge Grand Caravan
    I took a look at the online version of the owner's manual for your 2019 Dodge Grand Caravan and on page 305 it states that the rear jack location is located between a pair of down-facing tabs that are on the sill flange of the vehicle side of the body. I recommend checking your copy of the owner's manual to verify this. Since the Draw-Tite Max-Frame Trailer Hitch Receiver # 75579 installs behind your rear tires this jack location will not interfere with the installation process. You may...
