Chock and Lock

Mounting the Chock and Lock

Adjust the chock using the threaded rod and nut at the top of the unit. Simply place the chock, in the open position, between the tandem tires and turn the nut on the rod until the width of the unit fits the spacing of your tires. Then press the handle down into the locked position to hold the chock firmly in place. The handle can be locked with a padlock (sold separately) for additional peace of mind.

Love these two chocks. Keeps my trailer very stable. I've had them for two years purchased from eTrailer.com. One had a piece of rivet break off and the company replaced it per their Lifetime Limited Warranty.


Comments
Still an excellent purchase despite that piece of rivet that broke off.

we have been pleased with all the products we have ordered through etrailer. Unfortunately, in our case, many of these products including our trailer were lost in the Paradise Camp Fire. We still have the stabilizer, and if you look at our order history, we have started replacing some of the other items. My brother is new to owning a travel trailer and we have turned him onto e-trailer as well.

Liked the design of this chock-n-lock. Had one prior but lost it while camping in OK. I bit difficult to get a padlock on it with the tandem wheels so close together. But, then that means it'll be more difficult for a thief to take a set of bolt-cutters to cut off the padlock. Fair trade-off.

No instructions and watch out for your fingers while trying to adjust it. Once I figured the limiting nut, the wheel chock worked great. Easy to lock in, no wrench required.

Very easy to use and we felt more secure with our camper axles being locked in place. Make sure to measure tire gap as a larger clamp may be needed.

Holds trailer firmly and is easy to adjust. No more "will it hold" pieces of firewood for me. Unit has not rusted even after a year outside.

Seems to be well made and sturdy. I'm using this on a 21' trailer and notice no noticeable rocking with a single chock. This might be a little different with a longer trailer and different stabilizer jacks, so it's hard to say if it will work as well for every application. Overall, I'm happy with them.

Review from a similar Chock and Lock in Wheel Chocks


If your using conventional wheel chocks, and are tired of your rig rocking with every walk across the floor, I highly recommend these chock/stabilizers. They were easy to set up, and totally eliminate the rocking.

Review from a similar Chock and Lock in Wheel Chocks


Love them, It is amazing how little movement the trailer has now with these wheel chocks... Just make sure you get the correct width between the tires....

Adds additional stability, easy to install, no tools required ,great and simple product.

After about the third time I used them one broke . The aluminum rivet in the cam lever sheared off I would not recommend this product. They should not be made with aluminum pop rivets

TBW, I am in the customer service department at Ultra-Fab Products and I am sorry that one of your Chock has failed. I do want to let you know that we use steel rivets in our Chock & Locks and handle is held in place with a small machine screw and sometimes this screw will break. This is a proven product for us and we have very few warranty problems. Also your Chock & Locks do have a lifetime warranty so I would like to hear from you so we can help you with your broken Chock.

Ask the Experts about this Ultra-Fab Products Wheel Chocks

  • How to Determine the Correct Wheel Chock for a Keystone Bullet 281 bhs
    Most of the wheel chocks on the market are universal items and not trailer specific. To determine which Ultra-Fab Chock and Lock Wheel Stabilizer will work best for your Keystone Bullet 281 bhs, we will want to know the spacing between your tires (see photo). The Chock and Lock Wheel Stabilizer, # UF21-001060, will expand up to 5-1/4 inches wide and it is available as a two pack as part # UF21-001070. If your tires are further apart, then you could use the Chock and Lock Wheel Stabilizer,...

  • Wheel Chock and Stabilizer for Tandem Axle Trailer with 2 Inch Gap Between Front and Rear Tires
    The 2 inch spacing you have between the front and rear tires is enough to use Ultra-Fab chock # UF21-001060. It will fit tire spacing of 1-1/2 to 5-1/4 inches. I have included a link to a video review for you. For a set of 2 use # UF21-001070. You can also add a lock to the chock using # RM-301.
    view full answer...
  • 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.

  • Is Ultra-Fab Chock and Lock Wheel Stabilizer Sold in Pairs or Just 1 Chock
    If you were to order Ultra-Fab wheel chock # UF21-001060, you would receive 1 wheel chock. For a pair you can use part # UF21-001070. Having 2 will provide extra protection but using 1 is usually enough depending on your intended application. These chocks work well to prevent a trailer from rocking when parked. Having just one will reduce this rocking some but 2 will be ideal.

  • Compatibility of the Ultra-Fab Chock and Lock Wheel Stabilizers on Tandem Axle Trailer
    Since you are using blocks under the tires of your trailer when leveling, then the Ultra-Fab Chock and Lock Wheel Stabilizers, # UF21-001060, will work well for your application. The Ultra-Fab stabilizers will fit between the wheels of your axles and will eliminate the give between your axles. The chocks E-Z grip handle allows you to expand the stabilizer and can be lock using a pad lock to deter theft.

  • Wheel Stop for 1-1/2" Spacing on Tandem-Axle Trailer or RV
    There is not a wheel stop for tandem axle trailers or RVs that will work with less than 1" but there is something close. The Ultra-Fab Chock and Lock Wheel Stabilizer # UF21-001060 works with wheel spacing from 1-1/2" to 5-1/4". Additionally, if you have a tandem-axle trailer or RV, you really want more than 1" of space between them in order to allow for the wheel to expand as you are traveling.

  • Will JT's Strong Arm Stabilizer LC191025 Fit A 2021 Grand Design Transcend Xplor W/ Angled Jacks?
    It is possible that the JT's Strong Arm Jack Stabilizer Kit for Travel Trailers # LC191025 will work with your angled scissor jacks but only if there is a crossmember rearward of the rear jacks at a minimum of 4” to a maximum of 18”, and locate a cross-member or center compartment with a steel floor from 6”-18” from front of front jacks. If you do not have a crossmember in these locations the best option would be to use the Ultra-Fab Chock and Lock Wheel Stabilizer for Tandem-Axle Trailers...

  • Wheel Chock Recommendation for Launching a Boat
    On a slimy boat ramp there really aren't any traditional style wheel chocks I would feel comfortable recommending for you. If you have a tandem axle boat trailer I would recommend the # UF21-001060 as this installs between your tandem axle tires and will prevent the trailer from moving. See install video. Your best option would be to have at least one other person help you launch your boat. One to sit in the tow vehicle to cover the brake while the other launches the boat.

  • Is Lippert 5th Wheel Ground Control 3.0 Power Leveling Kit a good fit for Heartland Torque 325TQ
    Your 5th wheel trailer is on the large side at about 40 feet long and 8-1/2 feet wide with some slide-outs. The 4 point system # LC358590 would work well and give you stability that you are looking for, especially side to side stability. I think that you will be very happy with the added stability and amount of control the Lippert Ground Control 3.0 Electric 5th Wheel RV Leveling System will provide. As it comes it will fit 8, 10, or 12 inch frames. For even more front to back stability...
