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.

  • 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 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.

  • Availability of Lockable Wheel Chock for Trailer
    We have a similar wheel chock to the # SC47MR that is lockable with the Ultra Fab Wheel Chock and Lock part # UF21-001060 that allows you to run a padlock through to lock it in place as a theft deterrent but the # SC47MR is not lockable.

  • 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.

  • Recommended Ultra-Fab Chock and Lock Wheel Stabilizer for New Tires with a 5" Spacing
    While the smaller Ultra-Fab Chock and Lock Wheel Stabilizer for Tandem-Axle Trailers and RVs # UF21-001060 will initially fit, I do recommend going with the larger Ultra-Fab Chock and Lock Wheel Stabilizer for Tandem-Axle Trailers and RVs # UF21-001080. The Ultra-Fab Chock and Lock Wheel Stabilizer for Tandem-Axle Trailers and RVs # UF21-001060 fits wheel spacing between 1-1/2" - 5-1/4", while the Ultra-Fab Chock and Lock Wheel Stabilizer for Tandem-Axle Trailers and RVs # UF21-001080...

  • 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.

  • 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.

  • 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,...

  • 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...

  • Wheel Stop Style Chocks for Tandem Trailer with 1-1/2 inches Between Tires
    For a distance of 1-1/2 inches between the tires we have the Ultra-Fab Chock and Lock Wheel Stabilizer # UF21-001060 which would work great, the part # UF21-001091 you referenced has a minimum of 5-1/2 inches so it would not work.

  • 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.

  • 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.
