  • Quantity: 4 backing plates
  • Dimensions (each): 6" long x 6" wide x 1/8" thick
  • 4-Bolt mounting pattern: 4-1/2" x 4"
  • Limited lifetime warranty

Note: The included hardware lets you mount your E-track on surfaces up to 2" thick.

Product Dimensions

These backing plates provide more support for your E-track (sold separately) than only using wood or metal screws. Simply put, they allow the pulling force to be distributed over a greater area. This prevents your mower, ATV, or other heavy object from pulling your E-track away from its mounting surface and tearing up your trailer's wall or floor. They're perfect for trailers with thin walls or floors.

Pre-Drilled Holes

Product Dimensions

Pre-drilled holes accommodate the standard 4-bolt mounting pattern found on most horizontal or vertical E-tracks. There are also holes to accommodate D-rings, Snap-Locs, and odd-shaped tie-down anchors.

Simple, Bolt-On Installation


To install, drill pilot holes in your mounting surface as close as you can to each end of your E-track and directly in the middle so that the plates will be evenly spaced. Place your E-track where you're mounting it and insert the included bolts. On the opposite side of your wall or floor, place the plates over the bolts and secure them using the included washers and nylon lock nuts.

They work very well. I have had them installed for a year and am still very pleased with their fit, function, and ability to provide me with a sense of security about the e-tracks in my utility trailer while hauling my motorcycle. I used 3 per 5-foot section and feel much more confident than just screws.


Good product, but once again (as is the case with most of my orders) your shipping department blew it and didn't pack the order very well. There was ZERO packing material inside the box, so the items blew out the side of the box.
I'm seriously getting tired of complaining about your bad packing jobs, but I keep doing so because no one has fixed the problem yet.

To be honest we are always working on packaging solutions and sometimes the results are less than ideal. I will have our Customer Service department reach out to you and share the review with the shipping department.


Makes the E-track in our trailer to tie down our side-by-side sturdy without drilling or screwing into the frame rails.


These backing plates are an excellent addition for securing etracks to a wood floor. In my case my trailer. They are thicker than expected, the mounting hole arrangement gives flexibility in mounting, and the hardware is a perfect match for etracks. All of this makes installing etracks easier with the confidence your load will be secure. I’ll buy again.


Shipping was very fast even recieved before date due to arrive.Plates worked well with my DC Cargo vertical etracks. Good quality and was easy to install . Definitely would recommend when using on trailer deck or flooring that is 1/2 -5/8 thick .


Excellent quality! Compared to the other guys. The plates have a lot more options. The hardware is better quality, the washers fit better, it comes with lock nuts. Just better quality all around.


These E-tracks installed relatively easily on my new trailer using the available backing plates. Total install of 18' of track took less than 4 hours - a one man job except for the final tightening of the bolts included in the backing plate kit.


Works great. Easy install. Highly recom mended


All the parts work as advertised, great ..



Good nice backing plates for e tract,used them for other things to.


Easy to order, arrived earlier then expected. Up to date shipping info.


As usual my Etrailer order was spot on. Delivery was quick and the backing plates and E-tracks were high quality. You can buy from Etrailer with confidence. Their products are always as advertised and the customer service is excellent.



The product is still performing flawlessly, great purchase.


Exactly what we needed for our etrack system. Great price and fast delivery!


Works great! A big time saver and more peace of mind knowing it’s strapped down securely!


Highly recommend for mounting on wood bed. Just extra security.


Worked perfectly. Easy to install.


Excellent service. Order was seemless and showed up at my house a few days later. Will order from etrailer again!



Product is still like brand new. Works great! I hit a deer while hauling my trailer with my side x side in it and my side x side never moved. The tires on the side x side were strapped to the etrack on the floor of the trailer. This back plate holds the etrack down to the floor and performed flawlessly.


Used these plates and the included hardware as a backer to the (Erickson ATV E-Track Tie-Down Kit w/ Ratchet Straps and Wheel Chocks - 1,500 lbs - 4 Wheel Set) Item #EM98CV. They are too small to accommodate all 6 screw holes, but still worked out perfectly for me. I was able to get 4 of the 6 bolts through the plate by drilling 2 new holes before installation.


Everything is well made. As you know , I have ordered e track and a whole lot of backing plates to make my installation well built. Prices are good. The steel of the etrack seems to be very strong. Thanks.


A good versatile product,but my application the bolts were too short. A quick trip to hardware store ,everything good


Great price


Shipping, topself!


Excellent product, reliable service and quick shipping.


They worked great for what I needed. No issues out of them and they are holding up great.
Iv been happy with everything I purchase from etrailer


Works great

  • Is There a Rubber Backing/Spacer to Use Behind the etrailer E-Track Backing Plates
    No, we do not have any rubber backing/spacers to use with the etrailer E-Track Backing Plates # e66RR to help reduce galvanic corrosion. I would just source some sort of rubber material from your local home improvement store and cut it to the size you need. That will be the easiest way to get hands on with the material and make sure it works well for what you are needing.

  • Hardware Recommendations for Installing E-Track
    I didn't receive your photos, but the manner in which you attach the e-track to your trailer deck will completely depend on what the deck is constructed of and where exactly on the deck you'll be placing the e-track. Without knowing any details about that, I can't provide any specifics but I can certainly provide some general advice. If the decking of the trailer is thicker than 1 inch, I'd use 1/4 x 1 inch lag screws in every 4th hole or so, but I'd highly recommend situating the e-track...

  • Do I Need To Install Backing Plates For My 8' Section Of E-Track
    We do recommend backing plates for all e-track installations. They will provide additional support. You will need a set of four backing plates, part # e66RR, for an 8' section of E-Track. I have included a product description link, a weblink on how to install e-tracks, and a video of backing plates being installed below.

  • Can etrailer Horizontal E-Tracks e42VR Be Installed By An Amateur?
    You can absolutely install E-Tracks like the etrailer Horizontal E-Track - Black Powder Coated Steel - 2,000 lbs - 94" Long - Qty 4 # e42VR you were looking at in your Forest River Enclosed Cargo Trailer yourself. Now there are a few things to keep in mind, as no trailer is the same. The ideal way to install E-Tracks is in a location where you can screw into the frame of the trailer and not just the wood. Using 1/4" x 1" self tapping screws will be perfect for grabbing into the frame,...

  • Number of Backing Plates Needed For 5 Foot Long E-Track
    That is a good question, and you will need to use three backing plates for each 5 foot section of e-track, so the exact part you will need is the following: - etrailer E-Track Backing Plates w/ Hardware - Qty 3 # e46RR These will fit perfectly with the 5 foot sections of e-track that we have, which are available in either galvanized or black powder coated steel: - Black Powder Coated Steel: etrailer Horizontal E-Track - 2,000 lbs - 5' Long # e25VR - Galvanized Steel: etrailer Horizontal...

  • Recommended Hardware for Erickson ATV E-Track Tie-Down Kit
    The correct screw/bolt size for the Erickson ATV E-Track Tie-Down Kit # EM98CV is 1/4". The best hardware will depend on your exact application and the material and thickness you're attaching these too. If your mounting surface is no more than 2" thick I would consider using the etrailer E-Track Backing Plates w/ Hardware # e66RR to keep your wheel chocks secure.

  • Will Erickson ATV E-Track Tie-Downs EM98CV Be Able To Secure 2006 Kawasaki Mule 3010?
    Yes, the Erickson ATV E-Track Tie-Downs # EM98CV includes wheels chocks and straps for four wheels and will accommodate vehicles weighing in at 3000lb maximum with tires between 10" and 30" in diameter. Since your 2006 Kawasaki Mule 3010 weighs in right around 1500lbs this would be a perfect option for you. I do recommend adding two sets of the Backing Plates # e66RR to better distribute the clamping force of the bolts holding the e-tracks to the trailer. I included videos of the products...

  • Mounting Erickson ATV E-Track Tie-Down Kit to Plywood Floor in Enclosed Trailer
    One nice thing about the # EM98CV is you can use a variety of mounting hardware to suit your needs depending on where and what you're mounting them to. You can certainly use lag bolts to mount the wheel chocks to your plywood floor, this won't cause a problem. However, if you decide you want to get under your trailer to mount them, the best way to mount these is with the etrailer E-Track Backing Plates # e66RR.

  • Safe Working Load Limit of Erickson ATV E-Track Tie-Down Kit 4 Wheel Set
    The 1,500 lb safe working load limit of the # EM98CV is per pair of straps. This is the same as two of the # EM09160. Since this has two pair, the WLL would become 3,000 lbs. As long as you are not exceeding 3,000 lbs these are a great choice for your application. I also highly recommend the etrailer E-Track Backing Plates w/ Hardware # e66RR to keep them secure.

  • How to Set Up E-Track on Trailer Floor For Transporting 2 Motorcycles on Trailer
    There are so many variables involved here, including the size of the bikes, how you want them to sit in the trailer, the weight of the bikes and the geometry of the bike's frames that I couldn't begin to provide you with specifics, but I'd be happy to provide some general information that should prove helpful. If it were me setting things up, I'd use 2 lengths of e-track like the # E19148 mounted to the trailer floor, but run them in a side to side orientation, instead of lengthwise. Place...

  • Recommended Trailer Tie Down System For Hauling Vehicles In an Enclosed Trailer
    For your Dodge Challenger I recommend using the Erickson E-Track Tie-Down Kit # EM58523-09162-4. With this kit you get 4 e-track wheel straps that will provide you a great way of securing your Challenger. The straps will be easier to route around the outside section of the tires as you mentioned the Challenger sat very close to the ground. The straps will hold all 4 tires is place securely. This will allow the suspension in the Challenger to move freely which will be better over those...

  • Anchoring E-Track On Floor Of Van For Transporting a Motorcycle
    To secure the Erickson Horizontal E-Track # EM59150 you need to use the E-Track Backing Plates # e66RR to secure them to the floor. The screws can easily pull out of the plywood especially considering your van will be absorbing a lot of road shock. You will want to ensure that the plywood is also secured to the floor either with the backing plates or in another similar manner. This will ensure that your Harley stays secured to the floor and will not move. I recommend using the Erickson...
